What is Mauna Kea?

Mauna Kea is a massive Hawaiian shield volcano towering over 13,803 ft above sea level. It is the highest mountain in Hawaii’s archipelago and the Pacific Ocean’s most prominent peak.

What type of volcano is Mauna Kea?

First, it is a shield volcano characterized by its broad, gentle slopes. Shield volcanos have a shallow slope , with the top formed by layers of lava flow. These volcanoes let the lava flow easily and are known for their slow and rotational movement. This process creates the shield-shaped mountain, an iconic feature of Hawaii’s big island.

How old is Mauna Kea?

The Mauna Kea Volcano is nearly a million years old and took shape gradually. It started forming under the ocean’s surface around 700,000 years ago. Over the years, numerous explosive eruptions occurred, followed by slow, effusive lava flows.

As a result, Mauna Kea has formed a broad dome-shaped peak and enormous calderas. Geologists estimate that the last eruption of Mauna Kea happened about 4,500 years ago. Today, it’s regarded as a dormant volcano .

Where is Mauna Kea?

If you’re using a phone, click on the map below and use your fingers to zoom in or zoom out.

The perfect location for an observatory

It is relatively high above sea level, which means the mountain is above the lower atmospheric layers. As a result, it offers a clear view of the sky from a hidden location.

This makes it the perfect spot for observing sunrise and sunset, and the shape of the mountains provides a stunning view of the star-filled sky at night.

How many observatories are on Mauna Kea?

There are currently 13 operational telescopes on Mauna Kea. The journey to the summit of Mauna Kea is an adventure, but the real magic begins when you reach the top and find yourself surrounded by more telescopes than you can count.

Some observatories you can visit on Mauna Kea include the James Clerk Maxwell Telescope, Submillimeter Array, Very Long Baseline Array, Gemini Observatory, and many more.

Mauna Kea can be found on the Big Island of Hawaii . It is situated in the Mauna Kea Observatories, a world-renowned astronomy complex with several observatories.

These observatories include the Keck Observatory, Subaru Telescope, and Canada-France-Hawaii Telescope. The Observatory complex is accessible via Saddle Road from Hilo or Kona.

What makes Mauna Kea so unique?

Mauna Kea is the tallest mountain in the world if you start at the base of the actual mountain. Remember that the base of Mauna Kea starts below sea level (i.e. underwater).

Mauna Kea has a rich cultural and spiritual history. The mountain is considered sacred by locals and Native Hawaiians and is an essential site of worship for them. Ancient Hawaiian temples, or “Heiaus,” are near the mountain’s base.

Additionally, the mountain is considered an ideal location for astronomical observation due to its high altitude, perfect climate, and distance from large cities.

The observatories on its summit have led scientists to make multiple groundbreaking discoveries about the universe.

What does Mauna Kea mean?

Mauna Kea is also known as the “White Mountain” due to the snow-capped peak during winter. However, the mountain is breathtaking at any time of the year. Its summit provides a spectacular view of the surrounding ocean and volcanic peaks.

The valleys and ridges surrounding the mountain are home to an abundance of flora and fauna, including rare species of birds and plants. The hill is also host to multiple hiking and nature trails.

What to do at Mauna Kea?

The summit of Mauna Kea is accessible only through guided tours due to the harsh conditions and extreme altitude. These tours, however, are an unforgettable experience, as visitors can view the stars and galaxies through high-tech telescopes.

Enjoy the stunning sunrise and sunset views from one of Hawaii’s most incredible vantage points. The mountain also provides opportunities for skiing and snowboarding during winter, with the slopes ranking amongst the best in the world.

Reaching the Mauna Kea Observatory

We started our Mauna Kea Observatory adventure in the late afternoon. Our tour guide picked us up at a mountain base meeting point. The tour vehicles drove us up to the summit of Mauna Kea at an altitude of over 13,000 feet.

The journey up the mountain allowed us to witness some of the most incredible sceneries. The sight of the vast barren landscape against the clear blue skies was breathtakingly beautiful.

As you can see in the photo above, there’s nothing quite as spectacular as the pinks and blues as seen from such a high elevation .

The highest summit in the world

Upon reaching the summit of Mauna Kea, we were stunned by the spectacular view of the sunset. The golden-orange sun setting over the mammoth mountain landscape and sky was a unique sight that will always remain etched in our memories.

We were in awe of standing on the tallest peak in the world and could not help but appreciate the miracle that is nature.

Stargazing atop one of the tallest mountains in the country is a once-in-a-lifetime experience and a must-do activity if you’re on the Big Island. Without any light or atmospheric pollution to distract you, you’ll be able to see the night sky filled with stars, galaxies, planets, and so much more. 

However, getting to Mauna Kea can be a bit tricky, as it requires a long drive up to a high-altitude climate. 

If you would like to do Mauna Kea stargazing during your trip, then you can either drive yourself or book an organized tour. To help you decide what’s best for your group, we’ll share the pros and cons of each so you can plan a memorable and stress-free trip stargazing experience.

What is Mauna Kea?

Mauna Kea is an inactive volcano on the Big Island. It’s the highest point in the entire state of Hawaii, with a peak that stands over 13,800 feet tall (making it a little over a hundred feet taller than Mauna Loa – one of the largest volcanoes on the planet).

Because of the high elevation, Mauna Kea is an excellent place for stargazing. With a dry, cloudless, and nearly pitch-black sky, Mauna Kea has the perfect conditions for astronomical observation. Not only is it open to visitors, but it’s also used by professionals and scientists, including NASA.  

What are the Mauna Kea Observatories?

Perched on the summit of Mauna Kea sits the Mauna Kea Observatories. This 525-acre plot of land is home to 12 different observational facilities and 13 telescopes. The University of Hawaii operates two of them, while the others are governed by other agencies and countries. 

As a visitor, you won’t be allowed to go inside the observatories or use the telescopes. The only exception to that is NOIRLab does a limited number of tours at noon to their Gemini North Telescope . You must drive yourself to the summit.

But if you make the trek up to the summit during the day, you might be able to see the astronomers at work. The domes will be open, and the telescopes will be swung into position! 

Besides being on the summit, you also have the chance to check out the visitor’s center, The Onizuka Center for International Astronomy Visitor Information Station (VIS for short), which is located further down the slopes of the volcano.

Can You Visit Mauna Kea on Your Own? 

Yes! Although many people choose to visit Mauna Kea with an organized tour, it’s possible to go on your own. However, there are some rules and regulations you’ll need to follow if you plan to drive yourself up the volcano. 

The visitor center is open from 9 AM to 9 PM, although the road to the summit opens 30 minutes before sunrise and closes 30 minutes after sunset. You can visit anytime during operational hours, although many people like to come during sunrise or sunset for the view.

2-wheel-drive vehicles are not permitted past the visitor’s center, so be sure you go prepared! We’ll cover more on this below.

Mauna Kea Stargazing: Visiting on Your Own

Organized tours are expensive and often take up an entire day. While it is great to have a knowledgeable guide with you, some people prefer to go stargazing on their own. If you are planning to head up to Mauna Kea without a tour, there are some things to keep in mind to make sure your trip goes as smoothly as possible.

Tips for Stargazing at Mauna Kea

Beware of altitude sickness.

As the tallest peak in Hawaii, the high altitude levels on Mauna Kea are no joke. In fact, the air at the summit contains 40% less oxygen than at sea level! If you aren’t adequately prepared, you may get Altitude Motion Sickness (AMS), which can cause headaches, drowsiness, nausea, and loss of balance among other symptoms.

To prevent getting sick, there are some safety precautions you should take:

• Spend at least 30 minutes adjusting to the altitude change at the Visitor Center (9,200 feet)
• Bring and drink lots of water to stay hydrated
• Don’t drink alcohol before or during your visit
• Don’t do too much strenuous activity at the top. You should save your oxygen!
• Avoid high altitudes if you are pregnant, under the age of 13, or have poor general health

Join the Stargazing Program

Once a month, the Mauna Kea Visitor Center hosts a free stargazing event. As a group, staff members will take you to a private stargazing location where you’ll be able to spend two hours viewing the night sky. They’ll have telescopes set up and can answer any question you may have.

To join, make sure to reserve your place online in advance. You can come a bit early to watch the sunset before returning to the visitor center to start your stargazing experience.

Rent the Right Vehicle

To reach the summit of Mauna Kea, you’ll need to have a 4WD vehicle. The 8-mile drive from the visitor center to the peak is on steep, bumpy terrain, which means it’s not suitable for 2WD cars. If you don’t have an off-roading vehicle, you’ll still be allowed to go to the visitor center, although venturing any further is strictly prohibited.

When renting a car, make sure the rental company allows its vehicles to be driven up Mauna Kea. Some companies have regulations that prohibit this, so double-check before you leave the airport or rental car center.

It’s also important that you have enough gas to make it up to the summit and back. While the drive is doable on ½ a tank, we highly recommend filling up before going to Mauna Kea. You will burn a lot of gas as you make the climb to the summit. There are no gas stations after Waimea, so plan accordingly if you’re driving yourself!

Check out our rental car recommendations before you book!

Be Respectful

Mauna Kea is a sacred place, and according to Hawaiian mythology, the summit is home to benevolent spirits and gods, including Poli‘ahu, the Goddess of Snow. Historically, Hawaiian law stated that only high-ranking nobility were allowed up to the peak.  

While this has changed over time, it’s still vital that all visitors treat the volcano and the natural surroundings with respect. Make sure you stay on the road at all times and don’t pull over unless instructed.

Dress Warmly

As you might imagine, the top of Mauna Kea can be very cold. The average temperature at the peak is 32 degrees Fahrenheit (literally freezing!), although the wind chill can make it feel even colder.

For this reason, you’ll want to dress warmly. Make sure you have long pants, closed-toed shoes, and a warm jacket or sweater. You may also think about bringing thick socks, gloves, and a beanie, so be sure to add these to your Hawaii packing list !

Don’t Go Scuba Diving Before or After

Similar to flying, being at a high altitude can pose major risks for scuba divers. The decreased air pressure and build-up of nitrogen in the bloodstream can be extremely dangerous. If you want to go scuba diving after stargazing, you must wait at least 24 hours to adjust back to sea level.

The same applies to diving before your trip up the volcano. Because of the altitude change, you should also wait more than 24 hours to go up Mauna Kea if you’ve been scuba diving. 

How to Stargaze at Mauna Kea On Your Own

Now that we’ve gotten the safety information out of the way, let’s walk through what you’ll need to do to have an amazing experience stargazing at Mauna Kea!

One important thing to note is that the road from the visitor center up to the summit is closed 30 minutes after sunset. Therefore, you won’t actually be doing any stargazing at the peak. While you can drive up there for the view (and the bragging rights), you will be doing all your stargazing around the visitor center at a lower elevation.

Arrive Ninety Minutes Before Sunset

As mentioned, the road up to the summit closes 30 minutes after sunset. You’ll need enough time to make the drive and acclimate to the altitude change if you’re planning on watching the sunset from the top.

Therefore, we recommend getting to the visitor center 90 minutes before the scheduled sunset. That gives you 30 minutes to acclimate at the visitor center and another 45 minutes to 1 hour to drive to the summit. If there isn’t traffic, you can usually make the drive in about 30 minutes, although it can be longer if you’re stuck behind a slow driver.

Give Yourself At Least 30 Minutes to Acclimate

We can’t stress this enough! Unless you want to spend your entire evening feeling sick and dizzy, It’s important to acclimate to the change in altitude. You don’t want to just drive straight from the beach up to the peak without stopping to adjust, as this can be extremely dangerous.

The visitor center is located 9,200 feet above sea level, so you need to stop here for at least 30 minutes before heading to the summit. However, the longer you have here, the better. Some visitors even spend several hours here just to make sure. 

There’s a lot to see inside, including photos, diagrams, and models. You can also pick up a book or souvenir at the gift shop while you’re waiting!

Drive from the Visitor Center to Mauna Kea Summit

If you have a 4×4 vehicle with an allowance to go up Mauna Kea, then you can head to the summit before sundown. Remember that the road is long (8 miles) and very steep (~5,000 feet), so take your time.

Give yourself at least 45 minutes to an hour to go up the road from the visitor center. While the drive should take just 30 minutes, it will likely take longer due to the number of cars, slow drivers, etc.

If there are high winds, ice, or lots of snow, the road up to the summit might be closed. Before you leave, check the road conditions to see if it’s open to visitors.

Watch the Sunset

Once you’ve reached the peak, bundle up in your warm clothes and go out to watch the sunset. It’s a breathtaking sight to see it descend below the clouds. Make sure to bring your camera (and some sunglasses), as the colors are stunning from this high up.

Drive Back Down to the Visitors Center for Stargazing

Remember, you can only stay up at the peak for about 30 minutes after sunset. The road down to the visitor center can be quite dangerous in the dark, so you won’t be allowed to stay for too long. 

But once you arrive back at the visitor center, it’s time to go stargazing! 

Why Stargazing is Better at the Visitors Center

Despite what many people think, the visitor center is better than the summit for stargazing! That’s because it’s at a lower altitude, which means there’s more oxygen in the air. Getting less oxygen makes it harder to see the stars, even though you’re technically closer to them!

However, the summit is still the ideal place for astronomers. The telescopes they use aren’t affected by the lack of oxygen, which is why they’re situated at Mauna Kea’s peak, but many astronomers control the telescopes and view the images at lower elevations.

So, don’t be upset that you can’t stay on the summit after dark. The visitor center is still at a high enough elevation to make your stargazing trip a memorable one!

The Best Mauna Kea Stargazing Tours

While a DIY drive-up Mauna Kea is doable, it might be easier to go with a tour group. Not to mention, it’s always nice to have a knowledgeable guide with you to answer any questions you may have and help you see even more.

We recommend a tour for stargazing if you’re hesitant about the drive. Driving up or down the mountain at night is difficult – the road is windy, and completely dark, and the change in altitude is significant. Thankfully, there are some great options available if you prefer to go on an organized stargazing tour.

Stargazing Tour with Photos

A lot of stargazing tours last the entire night (10 to 12 hours!), which may not fit your schedule if you’re short on time. However, this stargazing tour is only 2 hours long, so it’s perfect for those who have other activities planned.

The tour is led by James, an analog astronaut and professional astrophotographer. He uses a telescope and laser pointer to show you exactly where to look for the most breathtaking views of the night sky. He’ll also take professional photos of you with the starry backdrop so you can have a unique souvenir to remember your time on the volcano.

Because this tour doesn’t go up to the summit, it’s suitable for kids or those with health issues. And if the weather or stargazing conditions are bad, you’ll get a full refund or opportunity to move your tour to a later date.

If you’re trying to get great photos throughout your vacation, check out our favorite photo spots .

Twilight Volcano and Stargazing Tour

This full-day tour allows you to experience the best of what the Big Island has to offer. You’ll start your morning with a coffee tasting at a local Kona coffee farm before heading to Punalu’u Black Sand Beach (one of the most unique beaches on the island!). From there, you’ll visit Hawaii Volcanos National Park, where you’ll see the Kilauea Iki Lookout, steam vents, and Halema’uma’u Crater.

After dinner at a local restaurant (which is included along with a picnic lunch), you’ll head up to Mauna Kea for an evening of stargazing. 

Mauna Kea Summit Tour

If you’re staying in Hilo, this is one of the best stargazing tours you can join. They’ll pick you up at a central location and whisk you up the slopes of Mauna Kea for an unforgettable evening. After a warm picnic dinner, you’ll visit the summit for a spectacular sunset before heading back down to the stargazing spot. 

Admire the different constellations and space objects through the telescope while sipping hot chocolate to stay warm. Your guides will also take photographs of the night sky that you’ll get after your tour! 

Parkas and gloves are provided, which is a huge perk if you don’t want to pack yours from the mainland. However, stargazing is not guaranteed, as cancellations due to poor or cloudy conditions may occur. Refunds are not offered for unfavorable conditions.

Kohala Coast Stargazing

Getting up to Mauna Kea can be a time-consuming venture. However, there are closer stargazing spots you can visit that don’t require lengthy drives, heavy coats, or acclimatizing to the high altitude.

This stargazing experience takes place at the Westin Hapuna Beach Resort , which is just 45 minutes from Kailua-Kona. Even though it’s at sea level, you can still enjoy dramatic views of the night sky with their high-tech telescopes! We did this tour and saw the moon, Saturn, and tons of stars, so it’s definitely worth it if you don’t want to make the long journey to Mauna Kea.

We highly recommend this tour for kids as it only lasts for one hour. And if your little ones are under 5, they get to go for free! Honestly, we were a little hesitant about this tour but we all had a great time and learned so much. We took our kids and our parents with us, and it was great for all ages.

Tips for Your Visit to Mauna Kea

A visit to Hawaii’s tallest mountain, Mauna Kea, is an absolute must-do if you’re visiting the Big Island of Hawaii.

Mauna Kea is actually the largest mountain on earth (when measured from its base to the summit). For Hawaiians, Mauna Kea is a sacred place, where the heavens connect to the earth. From the top of the mountain, you’ll get a glimpse of the entire Big Island. If the sky is clear, you may also be able to see Maui off in the distance.

As you plan for your trip, use our tips below to make the most out of your visit to Mauna Kea.

Book a Hotel Nearby

If you’re planning on visiting Mauna Kea, it’s best to book a hotel in Kona on the west side of the mountain, or Hilo to the east. To reach the summit, it will take you about 2 hours to reach the summit from either Kona or Hilo.

Kona is known for its extensive collection of upscale hotels and resorts. If you’re looking for luxury, the Four Seasons, Sheraton, and Wyndham are excellent options. If you’re on a budget, there are plenty of excellent hotels around Kona to suit your needs.

Hotels in Hilo aren’t quite so flashy. However, many are filled with charm and character. Several are located right on the bay front, offering great ocean views day and night.

Browse a full list of hotels on the Big Island

At 14,000 feet, the summit of Mauna Kea towers over the rest of the Big Island. In winter, it’s not unusual to see the peak covered in snow from your chair on white sandy beach. Even in the summer, temperatures regularly dip below freezing once the sun sets.

If you’re planning on visiting Mauna Kea, be sure to dress warm. Long pants, sweaters, jackets, mittens, and hats are all regular attire up at the top. The wind can blow hard at the top and you don’t want your visit cut short because you’re too cold to enjoy the view.

Plan for the Mauna Kea Sunset

A visit to Mauna Kea is great any time of day, but it’s especially worth the trip at sunset. From the top, you can watch sun fall into the ocean as the sky turns shades of red, pink, orange, and purple.

The show is just getting started once the sun goes does. As the light fades, the sky above seems to explode with stars. The Big Dipper and Little Dipper are easy to spot. It’s not unusual to see the cloudy Milky Way stretch right above your head.

High above the clouds, Mauna Kea is one of the best spots in the world for stargazing. In fact, many countries around the world have giant telescopes at the summit. Some are even open to the public.

Bring Your Camera

There’s no bad day up on the mountain. Sure, the wind may be blowing and the temperatures may drop, but the view from the top of Mauna Kea is always worthy of a picture. Or two. Or three. Don’t forget to bring your camera.

Rent a 4-Wheel Drive

The road up to the summit of Mauna Kea is mostly gravel and quite steep. If your heart is set on visiting the summit, we recommend renting a 4-wheel drive vehicle.

There are numerous rental companies based out of Hilo and Kona. In the past, 4-wheel drive rentals has lots of restrictions on where you could and couldn’t go. Before you pay for your rental, ask if your vehicle has any restrictions that may void your contract.

While a number of companies offer great deals around the island, if you’re not able to get your hands on a 4-wheel drive a tour a tour to the summit is a great option.

Book a Tour to Mauna Kea

A number of great local companies offer tours to the summit of Mauna Kea. Many will pick you up from you hotel in Kona or Hilo. As the road to the top is steep and narrow, this is an excellent option if you don’t want the added stress of driving. On the way to top, you’ll learn about the island’s geography, culture, and natural history from expert local guides.

Mauna Kea Summit Adventures ( http://www.maunakea.com/ ), is a great option if you want to catch the sunset and stargaze. Their full day tours take care of everything. You’ll ride in comfort up to the summit, stopping along the way for a warm meal. They even provide the super warm parkas and hot chocolate, so you won’t need to worry about freezing at the summit.

Get a Good Look at the Stars from Mauna Kea

On your way down from the summit, plan to stop at the Visitor Information Station. Nearly every night, the station hosts free public viewings of the stars. Volunteers haul out telescopes, pointing out planets, stars, and galaxies millions of light-years away.

On your next visit to the Big Island of Hawaii, be sure to make a trip to Mauna Kea. Whether you choose a self-guided tour in a 4-wheel drive rental or you opt for a local tour to the top, the views will make the whole trip worthwhile.

Mauna Kea Observatories

All telescopes except the VLBA

All telescopes except the VLBA antenna can be seen in this photograph. The three main loci of development can be seen – at the lower right are the submillimeter telescopes in submillimeter valley. In the center left are the Subaru telescope, the Keck telescopes and the IRTF. Behind, on the summit ridge, are the CFHT, Gemini north telescope, UH 2.2-meter telescope, UKIRT, and UH 0.6-meter telescope.

Caltech Submillimeter Observatory

At the left is the Caltech Submillimeter Observatory. The large cylindrical structure at the right is the James Clerk Maxwell Telescope. The building in the foreground on the right is the antenna assembly buidling for the submillimeter array. The array is not visible in this photograph; it extends to the lower right.

From left to right, the telescope structures are JCMT, Submillimeter array assembly building, CSO, Subaru, UH 0.6-meter, Keck 1, Keck 2, UKIRT, IRTF, UKIRT, UH 2.2-meter, Gemini, and CFHT. The true summit of Mauna Kea is located immediately in front of the UH 2.2-meter telescope dome in this photograph. In the distance is Haleakala on the island of Maui.

From left to right, the telescope domes are JCMT, Subaru, CSO, Keck 1, Keck 2, IRTF, UH 0.6-meter, UKIRT, CFHT, UH 2.2-meter, and Gemini. The submillimeter array will extend behind the JCMT.

The Subaru Telescope

The Subaru Telescope is being constructed by the National Astronomical Observatory of Japan. First light is planned for 1998, and it is expected to be fully operational in 2000. The building in the foreground is the support building, where telescope operators and astronomers will be located. This design was chosen to minimize sources of heat inside the telescope structure, in order to maximize telescope image quality (heat degrades image quality).

VLBA antenna

This antenna is one of a large network of radio antennas that comprise the Very Long Baseline Array. The Hawaii antenna is the westernmost antenna; the easternmost antenna is in the U.S. Virgin Islands.

Kecks and Subaru Telescopes

In the center are the open domes of the W.M. Keck Observatory. To the right is the Subaru Telescope. Some of the antenna pads for the submillimeter array can be seen to the right of the Subaru Telescope. These concrete pads have been painted brown to help reduce their impact. In the distance, at the left is the almost perfectly formed cinder cone Pu’u Hau Kea, and to its right is Lake Waiau, at an altitude of 13,020 feet. It has an area of about 40 acres.

Keck Telescopes

The mirrors of the Keck telescopes can be seen inside the open domes. The mirrors are relecting light from the sky, so appear blue. Both telescopes are pointing towards the north – a direction chosen to avoid getting sunlight on the telescope. Close-up photographs of the Keck telescopes may be found later in this series.

All of the optical/IR telescopes can be seen in this photograph. In the distance at the right is the Hawaii antenna of the Very Long Baseline Array, located about 2 miles from the summit. The submillimeter telescopes cannot be seen in this photograph.

The Gemini and UH 2.2-meter telescope

The Gemini telescope, on the right, is presently being built. Adjacent and to the left of the Gemini telescope is the UH 2.2-meter telescope. The extension at the top of the dome of this telescope houses a crane. This crane is used to bring the aluminizing tank to the telescope when the primary mirror is aluminized. (In most other telescopes, the mirror is transported to the aluminizing tank.) In the distance is the dormant volcano Hualalai.

Ridge near the summit

The ridge near the summit, only about 10 feet lower than the summit, was the first area on which telescopes were built on Mauna Kea. The UH 2.2-meter telescope (center) was the first large telescope on Mauna Kea. The Gemini northern 8-meter telescope is the largest and newest telescope in this area (open silver dome).

In the center are the open domes of the W.M. Keck Observatory. These are the largest optical/IR telescopes in the world. Each telescope has a mirror 10 meters in diameter. Each telescope mirror is made up of 36 separate precisely controlled segments, joined together in a honeycomb pattern. At the left of the photograph is the NASA IRTF. To the right of the Keck telescopes is the Subaru telescope (scheduled to become operational in 1999). In the valley below are the submillimeter telescopes – CSO (left), JCMT (center, open), and the submillimeter array. The roads leading to antenna sites for the submillimeter array (also scheduled to become operational in 1999) can be seen on the right. No array antennas had been installed on Mauna Kea when these photographs were taken.

In the foreground on the summit ridge, from left to right, are the UH 0.6-meter telescope (small white dome), the United Kingdom Infrared Telescope, the UH 2.2-meter telescope, the Gemini Northern 8-meter telescope (silver, open) and the Canada-France-Hawaii Telescope. On the right are the NASA Infrared Telescope Facility (silver), the twin domes of the W.M. Keck Observatory; behind and to the left of them is the Subaru Telescope. In the valley below are the Caltech Submillimeter Observatory (silver), the James Clerk Maxwell Telescope (white, open), and the assembly building for the submillimeter array.

Above the summit access road

From high above the summit access road, but about 500 feet lower than the summit (at approximately the altitude of the submillimeter telescopes), not all of the telescopes can be seen. The top of the Gemini dome can be seen directly above the summit. This photo shows how steep the access road is. The Keck telescopes and IRTF are hidden behind the summit ridge.

From an altitude of about 13,800 feet (level with the summit, seen on the left of this photo), the Keck telescopes are hidden by the summit ridge. The Gemini northern 8-meter telescope dome is the largest structure from this perspective. In the distance is Haleakala, on the island of Maui.

Keck and Subaru telescopes

The twin domes of the Keck telescopes are on the left. The Subaru telescope structure is behind them and to their right. Behind the telescopes is Pu`u Poliahu.

Richard Wainscoat in a Hughes 500

These photographs were taken by Richard Wainscoat in a Hughes 500 helicopter. The rear door of the helicopter was removed. The photographs were taken using a Mamiya 645 Pro camera mounted on a gyroscopic stabilizer, and with a Nikon N90S camera with telephoto zoom lens. Special thanks are due to the pilot, Marty Williams, for his excellent flying. This photo was taken by Andy Perala of the W.M. Keck Observatory, who provided a great deal of help in organizing this photo shoot..

Hale Pohaku

Because of the extreme altitude of Mauna Kea, astronomers and technicians must acclimatize and live at an intermediate altitude. The Onizuka Center for International Astronomy (also known as Hale Pohaku – Hawaiian for “Stone House”) has living facilities for up to 72 people working at the summit, as well as a visitor center and other support buildings. This photograph is partially obscured by drifting smoke from a distant fire – the 1998 winter was very dry, with drought conditions and extreme fire danger on the Island of Hawaii.

The NASA Infrared Telescope

The NASA Infrared Telescope Facility consists of a 3-meter infrared optimized telescope. It is operated by the University of Hawaii, Institute for Astronomy, for NASA.

Keck Telescope

The Keck 2 telescope of the W.M. Keck Observatory was the second 10-meter telescope to be built on Mauna Kea. It came into operation in 1996. Its 10-meter primary mirror comprises 36 separate hexagonally shaped segments. The primary mirror can be seen in this photograph, and its outer edge shows the hexagonal segments.

The primary mirrors of the two telescopes of the W.M. Keck Observatory can be seen in this photograph. At the left is the Keck 2 telescope, and at the right is the Keck 1 telescope. Behind the domes, a carport is being constructed to protect workers and visitors from falling ice.

The Canada-France-Hawaii Telescope lies at the northern end of the summit ridge, and was one of three telescopes that came into operation on Mauna Kea in 1980 (the others were UKIRT and IRTF).

Gemini Telescope

At the time these photographs were taken, the Gemini telescope enclosure was complete, and the telescope was being installed (blue structure inside the dome). The primary mirror for this telescope is scheduled to be transported to the summit later in 1998.

The meeting point for the Mauna Kea Summit tours depends on the tour option you select.

Check the booking page to know the exact meeting location before arriving.

The Mauna Kea Summit tours operate from 6 am to 10 pm daily.

The tour duration of the Mauna Kea Summit can vary depending on type of tour, the activities included, and the time of day.

Sunrise tours depart in the early morning hours, often before dawn, to ensure visitors reach the summit in time to witness the sunrise. These tours last around 8 to 10 hours, including travel time, acclimatization stops, and the time spent enjoying the sunrise spectacle.

Sunset and stargazing tours also involve travel time to the summit and time for acclimatization and stargazing activities. 

These tours start in the late afternoon and last around 6 to 8 hours, depending on the specific itinerary and the time of year.

Tours focusing on daytime activities, such as visiting the Mauna Kea Visitor Information Station, learning about astronomy and culture, and enjoying the panoramic views, can last around 4 to 6 hours.

The road to the summit is steep and winding, and driving slowly and carefully is recommended, especially due to the high altitude.

The best time to go to Mauna Kea Summit is in the early mornings and evenings to witness the stunning sunrise or sunset. Both experiences offer spectacular views and unique lighting conditions.

To catch the breathtaking sunrise, depart in the predawn hours and reach the summit before daybreak. 

If you prefer to experience the mesmerizing sunset, arrive at the summit in the late afternoon to witness the stunning evening display and take part in stargazing programs.

The Mauna Kea Visitor Information Station (VIS) usually opens in the morning, and you can learn about astronomy and the mountain’s cultural significance and enjoy the views.

If you prefer a less crowded experience, consider avoiding holidays and summer (May to August) vacation periods, as this is a peak tourist season in Hawaii.

Fall (September to November) and Spring (March to May) is generally a good time to visit Mauna Kea, offering a more peaceful and less crowded experience.

Here are some frequently asked questions about the Mauna Kea Summit.

Mauna Kea Summit stands at an elevation of approximately 13,796 feet (4,205 meters) above sea level, making it the tallest volcano in the Hawaiian Islands and one of the highest points in the Pacific.

Mauna Kea’s high elevation, clear skies, and minimal light pollution make it an excellent location for astronomical observations. It hosts a cluster of world-class observatories operated by various institutions, offering researchers unparalleled views of the universe.

Guided tours are available for visitors who want to experience the Mauna Kea Summit. These tours often include transportation, informative guides, and opportunities for stargazing, sunrise/sunset viewing, and learning about the mountain’s cultural and scientific significance.

The high altitude of the summit can cause altitude sickness for some individuals. Spending time at lower elevations before ascending to the summit can help acclimate. At a lower elevation, the Mauna Kea Visitor Information Station allows visitors to adjust before heading higher.

The road to the summit is steep, unpaved, and challenging to navigate. It is highly advisable to use a four-wheel-drive vehicle, as the road conditions can be demanding. Additionally, it’s worth noting that certain rental car companies may have restrictions on allowing their vehicles to be driven to the summit because of these road conditions.

The weather at the summit can vary significantly. It’s generally colder and windier than at lower elevations, and snowfall can occur during the winter months. Be prepared for rapidly changing conditions and colder temperatures.

You can drive to the summit independently, but it’s crucial to be well-informed about road conditions and altitude-related considerations.  Joining a guided tour is recommended for a safer and more informative experience.

Both sunrise and sunset views from the summit are absolutely breathtaking. Specialized tours are readily available for these experiences, and choosing to visit during these times provides awe-inspiring vistas and exceptional lighting conditions that make the visit truly remarkable.

Essential items include warm clothing, sturdy shoes, water, snacks, sunscreen, and medications. If you intend to engage in stargazing activities, it’s wise to bring layers of clothing and blankets to keep warm during the cooler nighttime temperatures.

How To Visit Mauna Kea Yourself

Updated: May 15, 2023

This dormant volcano located on Big Island is a 1hr and 15 minute drive from the Hilo area. It's known for stargazing and unforgettable sunsets! Not only is Mauna Kea the highest point in Hawaii, it's the highest point in the entire Pacific Basin at 14,000ft elevation. At the summit, more than a dozen telescopes from all over the world reside making Mauna Kea the largest observatory of its kind on the planet!

How to Drive to Mauna Kea Summit Yourself | 7 Things to Know

You do not have to book a tour to experience Mauna Kea! Being a part of a group tour or doing things on your own is a definitely a personal preference. As for me, I love going at my own pace and saving some money by not purchasing tours.

1. It will take you about 2 hrs to drive from sea level to the summit at 14,000ft. If you plan to visit Mauna Kea yourself it is required to have a 4WD vehicle to drive to the summit .

2. It is recommended to stop at the Visitor Center at 9,200ft elevation for 30mins to help reduce the risk of elevation sickness.

3. The summit is open to visit during the daytime and you can stay up to 30mins after sunset.

4. Keep in mind that sunset is a very popular time to visit the volcano. Parking availability is first come, first serve and you will be turned away if the lot is full, so be sure to arrive early.

5. Be aware of road closures . Since the elevation is so high the weather is very different than the rest of the island.

6. Make sure to dress warm, temperatures can drop to 30-40 degrees after sunset.

7. Unfortunately, you will not be able to go inside the telescopes or buildings at sunset. The Subaru Telescope does allow visitors during the day. You must make a reservation.

Warning: Wait at least 24hrs to visit Mauna Kea if you have been scuba diving! Snorkeling is not an issue. Children under the ages of 13 should not visit the summit. It is also not advised to go to the summit if you are pregnant or have a heart condition.

Stargazing at Mauna Kea

The summit is not accessible after sunset unless you book a summit and stargazing tour . They are quite expensive, so if you're looking to experience the stars yourself you can drive up to the visitor center at 9,200ft elevation (not to the summit). From the visitor information center you can actually see more stars even though you are at lower elevation. At the summit the lack of oxygen changes what the naked eye can see.

Looking from a telescope at higher elevation is obviously the best for scientific research, but for just witnessing a starry sky on a clear night, the visitor center is more than amazing! The Visitor Information Center used to offer a free stargazing program on select days. Due to Covid the program has been suspended until further notice and is no longer offered to the public. Hopefully the program returns soon!

For the best views at night pay attention to the moon phases and weather conditions. A full moon lights up the night sky taking away from the stars and will flood your photos with light. Going 4 days before or after a new moon is best for viewing and photography.

Visiting Mauna Kea: Sunrises, Sunsets, & Stargazing

Mauna Kea is one of the must see spots on Hawaii and for people who love mountains and astronomy, it’s one of the top sites in the world. It’s also a sacred place to some natives and rich in ancestral history.

Visiting Mauna Kea isn’t as easy as just showing up to the access road, though.

Instead, you’re going to want to plan ahead to make sure that you’ll be allowed up on the summit so that you can catch a spectacular sunrise or sunset. And don’t forget about stargazing.

In this guide, I’ll tell you everything you need to know about visiting Mauna Kea.

Table of Contents

Overview of Mauna Kea

Let’s start off with some basic info to help you get an overall feel for Mauna Kea.

Mauna Kea is one of the four active volcanoes on the Big Island. It last erupted about about 4,500 years ago and it is believed that the volcano will erupt again .

Two common ways to experience Mauna Kea include: 1) going to the visitor center below the summit and 2) venturing up to the summit.

The Maunakea Visitor Information Station (VIS) sits at about 9,300 feet elevation and is located about 1 hour and 10 minutes from Kailua-Kona and about 45 minutes from Hilo.

The summit of Mauna Kea rises to 13,803 feet and it takes about 30 minutes to get from the visitor center up to the summit.

There are about a dozen observatories up on the summit including the famous Keck Observatory, home to the 3rd and 4th largest telescopes in the world! (In case you’re not aware, Mauna Kea is arguably the best place in the world for astronomy.)

Being the tallest point in Hawaii, Mauna Kea is considered sacred by some native Hawaiians as it holds lots of ancestral significance and ties to their stories of creation.

The construction of telescopes on top of the mountain has been a source of conflict, so it’s good to remember that and to always be respectful.

Things you need to know about visiting Mauna Kea

Here are a few things you want to know before heading up to Mauna Kea.

Give yourself time to acclimate

The Mauna Kea staff recommends that you spend at least 30 minutes at the visitor center acclimating — even better if you can spend one hour.

In an ideal situation, you would be able to spend a day or two acclimating. For example, if you were climbing in the Rocky Mountains you could stay in a mountain town for a night or two so that you’re going from something like 8,000 feet to 14,000+ feet.

But on the Big Island, there is a chance you will be going from sea level all the way up to nearly 14,000 feet which is a heck of a swing in elevation !

So you definitely want to do all that you can to acclimate which would mean spending some time at the visitor center. You’ll also want to stay well hydrated the day of your trip.

If you start to experience symptoms of altitude sickness, you’ll want to come down ASAP.

These symptoms include :

• Feeling and being sick
• Loss of appetite
• Shortness of breath

Weather and what to wear

Mountain roads are always a little bit suspect because they can often get shut down temporarily for various reasons including maintenance, accidents, and of course the weather.

On occasion, there could be a lot of snow or ice on top of the mountain.

If it’s very recent then the rangers may feel that the road is unsafe for the public and close it down.

Also, sometimes the wind can get crazy up there and unsafe so the rangers could also shut it down for that reason. This is why it’s a good idea to check out the latest road conditions and weather conditions .

And remember that at high altitude, weather conditions can change extremely quickly. It’s not uncommon for forecast to be inaccurate at such a high elevation so it’s good to be ready for all sorts of conditions.

As a rule of thumb, temperatures usually drop about 3° F for every 1,000 feet. So with the mountain being almost 14,000 feet, the temperatures up there could be somewhere around 40 ° to 45° F colder than at sea level!

Having a gaiter or some type of face mask to cover your face from the wind along with a solid puffer jacket and beanie, is a great way to be prepared for even the coldest conditions. Even in summer, the lows can be in the 30s!

Tip: Call the visitor center before heading out to ask about the latest conditions and confirm everything is open.

If you want to see snow on top of Mauna Kea you can probably see that all the way into the summer or at least traces of it. We visited during late March and there was plenty of snow. I was actually really surprised at how thick the snow pack was and it was pretty cool to touch “Hawaiian snow.”

Get your vehicle ready and in order

Officials require you to take a four wheel drive vehicle to get up to the top.

A ranger will likely check to make sure that you have four-wheel-drive and that you know how to operate it because they want you to drive in four low (4L) going up and coming down. They also requested us to put it in manual on the way down and to keep it in second or third gear.

The ranger will probably go over the safety techniques for utilizing your brakes so that they don’t get cooked and you don’t find yourself in danger.

But in a nutshell, you basically just don’t use your brakes except for very few instances (e.g., around turns).

Whenever you come down they will do a brake check and check out the temperature of your brakes to see if you have been applying them too much.

If your brakes are too hot, I’m guessing that they will ask you to pull aside and wait but the ranger gave us a thumbs up after checking our temp so we are good to go.

Make sure that your vehicle is not low on gas and that you have at least half a tank of fuel because the last thing you want to do is get stuck up there.

They also want your vehicle to be clean (not bringing up a bunch of mud caked on the tires). This is because you could be bringing invasive plants up to the top which can affect the ecosystem.

And finally, if you are taking a rental vehicle up to the top make sure that you have permission. Not every rental car company will allow you to head up to the top.

Health status

They recommend not bringing children 13 years old and younger because they tend to have issues at high elevation.

I don’t think this is a hard rule and if you have a kid that has had no problem at high elevations (e.g., has hiked a 14er) then you may be able to explain that to the ranger and they could let you through.

But they also recommend not going up there if you have a pacemaker, cardiac or respiratory issues, or are pregnant.

And if you have been scuba diving in the past 24 hours, they advise you to not go up to the top.

In fact, I don’t even think that if you have scuba dived recently that you should even be driving on the saddle road since the elevation hits over 6,000 feet.

On our visit, we did the amazing manta ray night dive which meant that we had to push Mauna Kea out a couple of days to make it work. So plan accordingly!

Mauna Kea is a no-fly zone so drones are not permitted at the visitor center or at the summit.

There was a group of young people (wow, I sound old) out with a drone when we visited for sunrise and they kept flying it almost the whole time.

Not only was this against the no-drone policy but it also was a highly annoying to listen to while trying to appreciate the beauty of a serene sunrise. Drones flying overhead could also affect readings for the telescopes I’d guess. So please don’t be inconsiderate like these people.

There are some portable toilets near the summit so if you need to go you don’t have to come all the way down.

What is the road to the summit like?

The access road up to the Mauna Kea summit is paved in some parts and then a dirt road in other parts.

It’s a pretty wide road and while there are not rails on all places, it never felt like a “scary” mountain road to me. Don’t get too comfortable on the road but it just wasn’t that bad to me.

Also, I usually take some kind of motion sickness supplement before heading up on a mountain road but I did not do that for this one. Aside from some switch backs in the beginning, the road is not your typical endless winding mountain road.

Visiting Mauna Kea for sunrise

We chose to visit Mauna Kea for the sunrise and it was a s pectacular decision .

First, we arrived at the visitor center about two hours prior to sunrise. This was late March which meant we arrived about 4:20 AM. (Remember, the actual sunrise time will be a couple of minutes earlier at such a high elevation.)

There was only one other vehicle in the parking lot and so we decided to set up there but cars were coming in every few minutes.

At this time, the moon had already set and so the skies were super dark and the Milky Way had risen over the eastern horizon in spectacular fashion.

We allowed our eyes to adjust while getting some photographs of the Milky Way.

The challenge with getting astrophotography shots at the Mauna Kea visitor center is that there is a fair amount of vehicle traffic going in and out. This means that you have headlights or brake lights affecting your photos with lots of stray light.

It might be a good idea to venture down one of the trails to get away from the parking lot although it’s really hard to completely remove the possibility of headlights getting in your shots with long exposures unless you are completely isolated.

About 50 minutes before the scheduled sunrise time we made our way up to the summit but first we had to get through the ranger station, which involved checking in and getting a safety brief about all of the different factors mentioned above.

Visiting Mauna Kea for sunset

Visiting Mauna Kea during sunset is going to be the most popular time which means you’ll be facing more crowds.

Even when things are pretty busy, you still should be able to find a parking spot on top of the mountain as it’s usually only during the holidays that things get really crazy up there.

You’ll probably want to arrive on the summit at least 30 minutes prior to the sun setting. Keep in mind that they will close the access road about 30 minutes prior to sunset.

Because you need at least 30 minutes to acclimate, this means arriving at the visitor center at least one hour prior to sunset. Personally, I would try to arrive about 1.5 hours before sunset.

Just like the sunrise is a little bit earlier, the sunset will be a couple of minutes later than the stated time so keep that in mind. (It’s estimated that you add or subtract one minute for every ~5,000 feet of elevation)

To pass time, you can spend time checking out the visitor center or wandering around on one of the trails.

Just remember that the visitor center is also pretty high altitude (9,300 feet) so you may not want to do too much wandering if you are not used to high elevation sites.

Also, while you may be tempted to get up to the summit extra early, if you are prone to altitude sickness then spending less time up there is better so don’t leave the visitor center too early.

Mauna Kea Stargazing

In a perfect world, you could drive up to the top of Mauna Kea at any hour, sit down with a telescope, and admire the heavens for hours.

However, that’s not quite how it works.

First, because the summit is nearly 14,000 feet, your eyes will not be receiving as much oxygen as they would at a lower elevation.

This means that you won’t be able to observe the dim and faint objects as well as you could at a lower elevation such as at the visitor center. So you wouldn’t necessarily want to set up with a telescope on the summit.

Also, a lot of the telescopes on the summit are not your typical refractor or reflector telescopes. They rely on a lot of imaging and computers.

In the past, you could book a tour of the observatories to check them out but that is not currently offered.

However, there are still options for stargazing at Mauna Kea.

Typically, a stargazing tour will take you up to the top of the summit for sunset and after admiring the sunset you come back down to the visitor center and that is where the stargazing will take place.

You can schedule a free stargazing experience with the University of Hawaii but as of March 2023, they only offer these like once a month and you have to make reservations .

You can also book tours that will take care of your transportation, provide you with snacks, and give you some telescope time.

Another option could be to hope for astronomers to be set up at the visitor center. It’s possible that they could welcome you to use their scope to admire the sky.

This is one of the major drawbacks of going for a sunrise visit because the visitor center will not be open and chances are you won’t be able to secure a stargazing tour.

However, if you have your own gear or just want to get astrophotography shots then sunrise can be a good time to visit.

Hiking on Mauna Kea

I hate to break it to you but whenever you drive up to the “summit” of Mauna Kea, you actually are not on the summit.

However, from the summit parking area you can access the 1 mile Hawaii Highpoint Trail that will take you to the top of the summit. The elevation gain is only about 260 feet so this would normally be an easy hike but because of the elevation, it becomes more of a challenge.

Make sure that you are physically prepared to take on this hike and if you are already struggling with the high altitude, it may be better to pass on the hike.

We visited when the summit was covered in snow/ice and so we did not attempt the hike because we didn’t have any crampons which may have been needed.

For avid hikers, you also have the option of hiking up to the summit from the visitor center via the Mauna Kea-Humu’ula Trail. This is a major hike with nearly 5,000 feet of elevation gain and 13.5 miles round-trip.

Based on hike reports, it doesn’t appear that the trail is very steep which makes the hike a lot more doable but still I would not attempt this hike unless you have some real hiking experience and understand how your abilities hold up at high elevations.

I loved visiting Mauna Kea for sunrise and seeing the brilliant Milky Way at the visitor’s center. But I also can’t wait to get back to check out at sunset and perhaps book a stargazing tour as well as make my way to the top of the summit.

I’d say that it’s definitely worth visiting Mauna Kea but that you need to make sure you are well prepared because of all of the requirements and challenges with heading from sea level to around 14,000 feet.

pretty cool! that’s one of my Jeeps in the photo. corp rental agencies don’t let you go up the mauna but we do at Big Island Jeep rental. https://www.bigislandjeeprental.com/maunakea aloha! -Joe

You mention those 13 and younger, as well as those with heart issues, pacemaker, pregnant, etc. shouldn’t visit due to safety. Can they still enjoy the visitor center and not go up the summit? Or is the visitor center even as issue for this group of people? If yes to the visitor center, is it even worth it? (are there still good views?)

Decommissioning of Mauna Kea observatory set to resume after winter pause

HONOLULU (HawaiiNewsNow) - Decommissioning of one of the observatories on Mauna Kea is set to resume.

Crews will once again begin the process of removing the Caltech Submillimeter Observatory in mid-April, officials said.

It comes following a pause for the winter.

The next steps include completing interior deconstruction and removal of the observatory dome. Then, the foundation will be removed and the land restored.

The cost of decommissioning is expected to exceed $4 million, funded primarily by the Gordon and Betty Moore Foundation and Heising-Simons Foundation.

The decommissioning is expected to be finished this year.
