10 Best Mammoth Cave Tours Worth Your Time

This post is all about the best Mammoth Cave tours in Mammoth Cave National Park! You’ll find an overview of the different tours, travel tips, effort level listings, and estimated times based on our personal experiences hiking Mammoth Cave National Park.

In the beginning of autumn, I went on my first Mammoth Cave tour. I sat – legs pressed tight against a bench, feet clacking the ground – under the wide awning of Shelter A, waiting for a ranger to herd me (and a hundred or so other tourists) into the belly of the longest cave in the world. We walked and walked and walked some more. We climbed up and down thin, platformed stairs. We paused and gasped as the cave curved and snarled and dropped and twisted. Mammoth Cave’s pathways are serpentine; its walls are textured. And I was enamored by it all.

I returned to Mammoth Cave National Park often after, each time with the intention of taking one guided trip (sometimes two, much to the misery of my calves) through the cave itself. On those ranger-led tours, I chatted with travelers and staff, die-hard cave lovers and new-to-the-cave-scene visitors. Tour-by-tour, I fell deeper and deeper in love with Kentucky’s karst landscape.

Now, having been on almost all the Mammoth Cave tours (with the exception of their crawling tours), I feel ready to share my favorites.

Here are Passport To Eden’s top picks for the best cave tours at Mammoth Cave National Park!

Editor’s Note: Mammoth Cave tours are seasonal and not necessarily offered year-round. Sometimes tours close for construction (one of my favorite mammoth cave tours was closed in 2023 for this very reason. The goal was to make paths to be more accessible in the future). The best place to check what tours are available right now is the National Park website ( I’ll link it here ). I also tried to include a list of phobia warnings based on my own personal experiences on each of the cave tours. If you experience any cave-triggered phobias, I highly recommend talking with one of the rangers at Mammoth Cave National Park (you can reach them at 270-758-2180) before booking a tour. They can help you decide which tour (if any) might suit you best!

Historic Tour

Mammoth Cave has long been a place for the curious. Even before it became integrated into the National Park system in 1941, tours were being led down and through its hidden alleys and layered passageways. The Historic Tour is the oldest, continually operated tour at Mammoth Cave . It’s also the most popular .

Go for the atmosphere: the gaping, moss-laden Historic Entrance; the vaulted, limestone ceilings; the remnants of 19th century century saltpetre vats . Go for the route too. You’ll stroll through wide and thin areas of Mammoth Cave. You’ll pass a coffin-shaped rock that looks like it’s been plucked from the pages of an old vampire novel. You’ll duck and twist and shimmy through Fat Man’s Misery (though I’d personally call this portion of the cave Anybody’s Misery). And by the end of your tour, you’ll be left with no doubts as to how Mammoth Cave got its name.

General Info

ESTIMATED TIME: 2 Hours (Allot 2.5 hours) STAIRS: 540 EFFORT: Moderately Strenuous COST: $20.00 Per Adult PHOBIA WARNINGS: Claustrophobia, Nyctophobia, Agoraphobia

Frozen Niagara Tour

Quick, short, and low-in-effort , The Frozen Niagara tour is hands-down the easiest tour offered at Mammoth Cave National Park. Don’t be fooled by the sketchy looking entryway: this is one of the most beautiful sections of Mammoth Cave . Within a small, dark, fourth-of-a-mile stretch, you’ll see wrangled beards of limestone, spirals of stalactites, and ice-like distortions of flowstone. Your tour guide will brief you on the geology of Mammoth Cave , the story behind the Frozen Niagara entrance, and some of the keystone species you might see at Mammoth Cave National Park (this part of the cavern is usually crawling with cave crickets).

ESTIMATED TIME: 1.25 Hours (Allot 1.5 hours) STAIRS: 12 With Optional 98 Stairs To The Drapery Room EFFORT: Easy COST: $18.00 Per Adult PHOBIA WARNINGS: Arachnophobia, Nyctophobia, Agoraphobia

Cleaveland Avenue Tour

The Cleaveland Avenue Tour is one of the most underrated Mammoth Cave tours. If you’re visiting Mammoth Cave for the first time and want to get a feel for the length of Mammoth Cave without the stress of a large group size, this is the tour I’d recommend the most! Be warned: there are lots of steps up front and towards the end. But the path in-between is nice and gentle and compact . It’s a hike that’s strenuous in bursts, more tiring than difficult . And the reward is floral gypsum , white petals of calcium sulfate that choke cracks and crevices. You’ll amble and ramble and snap photos. And as you stroll through Cleaveland Avenue, your tour guide will introduce you to Mammoth Cave’s geology, topology, and history .

ESTIMATED TIME: 2 Hours STAIRS: 400 EFFORT: Moderate COST: $22.00 Per Adult PHOBIA WARNINGS: Nyctophobia, Claustrophobia, Agoraphobia

Grand Avenue Tour

The Grand Avenue Tour is intense. It’s stair after stair, incline after incline. You’ll trek through sparkling passageways and squeeze into slot canyons and amble past rich tapestries of flowstone. You’ll experience Mammoth Cave to the fullest – its highs and lows, its dimness and darkness, its emptiness and too-muchness. Grand Avenue’s variation alone it makes it one of the best mammoth cave tours, but it’s also one of the most difficult . The pace tends to be slow and unhurried ( there are even restroom breaks) to accommodate, but the length will absolutely test your legs. This tour is long. You’ll spend half-a-day in a cool, dark, seemingly endless underground . At times, the landscape will feel (and look) hellish. But if you love caves and enjoy Stairmaster challenges, you’ll feel right at home in this tour.

ESTIMATED TIME: 4 Hours (Allot 4.5) STAIRS: 1313 EFFORT: Strenuous COST: $35.00 Per Adult PHOBIA WARNINGS: Claustrophobia, Acrophobia, Arachnophobia, Nyctophobia, Agoraphobia

Violet City Lantern Tour

Whilst at Mammoth Cave National Park, I tried asking as many park rangers as I could find what their favorite tour was. The overwhelming response? The Violet City Lantern Tour . This is one the most dramatic Mammoth Cave tours. Here’s what I love about it: Violet City swoops you back in time to an era of early exploration , an era where your eyes depended on the soft, intimate glow of lantern-light . So as you hold up your lantern to Mammoth Cave’s water-cut nooks and crannies, you’ll tap into the past. But you’ll also focus on the little details – the here-and-now, the what-was and what-could-be.

ESTIMATED TIME: 3 Hours STAIRS: 160 EFFORT: Moderate COST: $25.00 Per Adult PHOBIA WARNINGS: Claustrophobia, Acrophobia, Nyctophobia, Agoraphobia

Gothic Avenue Tour

One of my favorite Mammoth Cave tours was the Gothic Avenue Tour (which to me felt a lot like The Historic Tour without the severe claustrophobia moments). The Gothic Avenue tour is dark and moody . It’s theatrical in its form and shape. Spheres of light are cast onto historic graffiti burned into Mammoth Cave’s walls. Monuments (old Jenga-ed stacks of rocks) are strewn along the edge of the trails. You’ll see broody stalactites and stalagmites droop down below blackened shadows. You’ll crescent moon around a dramatic ring of formations (known as The Bridal Altar), which devilishly drips down to hard, compact ground. The atmosphere of Gothic Avenue is gloomy and eerie. Go in October if you can (this is the perfect tour to take during spooky season).

ESTIMATED TIME: 2 Hours STAIRS: 160 EFFORT: Easy COST: $19.00 Per adult PHOBIA WARNINGS: Nyctophobia, Agoraphobia

River Styx Tour

I was told by a park ranger that the River Styx Tour is often touted as one of the most underwhelming tours at Mammoth Cave. “It’s because people expect to go down to the water,” he said. And while you do see water on the River Styx tour , you see it from above . You catch a small glimpse of it (just a glimpse). Know that this is less of a river tour, and mostly a mashup of many other Mammoth Cave tours . The River Styx trek (which is slick and muddy and wet in some areas) covers the entire Historic Route (truth be told, I was not looking forward to walking through Fat Man’s Misery again). It also injects some elements of the Violet City Lantern Tour and the Mammoth Passage Tour.

ESTIMATED TIME: 2.5 Hours (Allot 3) STAIRS: 600 EFFORT: Moderately strenuous COST: $22.00 Per adult PHOBIA WARNINGS: Claustrophobia, Nyctophobia, Acrophobia, Agoraphobia

Domes & Dripstones Tour

Like Frozen Niagara, Domes & Dripstones walks you through some of the prettiest sections of Mammoth Cave. It’s a lot more strenuous than Frozen Niagara though (according to the ranger who led our tour, this is the hike he’s seen the most people end up in need of medical evacuation – eeeep ). And after negotiating the steps past the entrance, I could see why. On the Domes & Dripstones tour, you knock out 280 stairs in the initial descent . The steps get smaller and smaller as you go farther and farther down. At the choke points, my feet were barely covered by the stairs. But wow, oh wow, once the stairs taper off, you’ll see one of the most beautiful sides to Mammoth Cave. This portion of Mammoth Cave isn’t dry and clean-cut. It’s moist and layered and filled with formations .

Side Note: I definitely felt like I gained the most knowledge from this tour. There were two ranger-led “Ask Me Anything” moments where our group got an opportunity to sit down on a handful of benches (arranged classroom-style right in the cave) and shoot questions. Y’all, I learned so much from the open-ended style of these portions, so if you’re looking to grasp more of the history and geology of Mammoth Cave, I highly recommend this tour!

ESTIMATED TIME: 2 Hours (Allot 2.5) STAIRS: 500 EFFORT: Strenuous COST: $21.00 Per Adult PHOBIA WARNINGS: Claustrophobia, Nyctophobia, Acrophobia, Agoraphobia

Self-Guided Tour

For a quick in-then-out jaunt into Mammoth Cave, opt for the self-guided tour . You still need a ticket (first come, first served), but once you’ve strode down past the Historic Entrance, you can walk around and read the placards at your own pace . This is a popular option for those planning a last-minute stopover at Mammoth Cave.

The self-guided tour showcases a large , wide open, level snapshot of Mammoth Cave, making it more accessible to people who might experience claustrophobia, acrophobia, and agoraphobia. There is a guided version of this tour too ( The Mammoth Passage Tour ), but if you get a chance, try booking one of the other Mammoth Cave tours on this list instead (for a more in-depth Mammoth Cave experience)!

ESTIMATED TIME: 20-30 Minutes STAIRS: 130 COST: $8.00 Per Adult EFFORT: Easy

Wild Cave Tour

While I do not intend on going on any of the crawling tours at Mammoth Cave (I looked at one of the holes you have to squeeze whilst on another tour and no, just no), I do still want to mention one crawling tour in this guide. Here’s why: everyone I spoke to who has done the Wild Cave Tour in the past has absolutely loved it. Apparently, you crawl on your hands and knees and push your body through small gaps in the ground. You don’t just get to see Mammoth Cave, you get to feel it. The Wild Cave tour offers a tactile way to experience Mammoth Cave. It’s supposed to be fun and challenging and adventurous .

ESTIMATED TIME: 4 Hours EFFORT: Very Strenuous PHOBIA WARNINGS: Claustrophobia, Nyctophobia, ACROPHOBIA, Agoraphobia COST: $46.00 Per adult

Did you find this guide to the best Mammoth Cave tours helpful? Do you have any questions? Let me know in the comments below! As always, I love hearing from you.

Pack With Me (WHAT I BROUGHT TO MAMMOTH CAVE)

• 🥾 Merrell Moab 2 : these shoes got me through every tour in Mammoth Cave
• 💧 Hydroflask : I brought this stainless steel water bottle (keep in mind, only clear water bottles are allowed on Mammoth Cave tours, but I didn’t feel like buying a new one and no one commented on my bottle being opaque ☺️).
• 🥜 Sahale : since no food was allowed in the cave, I kept this nut mix in my car and snacked on it after each tour (Sahale’s pomegranate vanilla cashews have my heart and soul 😋)
• 🧣 Light Sweater : Mammoth Cave tends to be a bit cold (in the mid 50s) so I opted for a light, long-sleeved, breathable sweater
• 📷 Sony Alpha a6400 : this is the mirrorless camera I personally used to take photos and film videos (I love that it has a flip-out screen)
• 🎒 Sling Backpack : this comfy little crossbody canvas rucksack was (and still is) my go-to day hiking bag

A view of the Green River from a bluff in Mammoth Cave National Park framed by redbud trees

The rolling hills of central Kentucky look solid enough where the well-worn foothills of the Appalachian Mountains slide into the flatter, fertile farm land of the Mississippian Plateau. But laced underneath that pretty landscape of telescoping green slopes is a vast network of caves, sink holes, and underground creeks that stand in stark contrast to the sunny spreads of spring wildflowers like trillium, dwarf iris, trout lily, and phlox above ground. And one of those caverns is Mammoth Cave, the longest cave system anywhere in the world. 

Humans have been exploring Kentucky's hidden depths for over five thousand years. Down here in the dark, there is evidence of the first intrepid visitors to what is now known as Mammoth Cave, who carried burning reed torches into winding, unmapped passageways. Now scientists have determined Mammoth Cave extends for over 400 miles. It winds down in numerous layers carved over millions of years by trickles and torrents of water making their way to join the wide Green River.

These days, you don't need torches to see the upper reaches of Mammoth Cave, now softly lit by electricity, punctuated by park rangers ready to explain the cavern's many features, and the sometimes unusual ways the cave has been used since the arrival of European settlers in the 1700s.

Editor's note: During  COVID-19 , please check the latest travel restrictions before planning any trip and always follow government health advice. Events may be subject to change.

Mammoth Cave history

Legend has it that a bear hunt is what lead the first non-Indigenous person to the entrance of Mammoth Cave, which sits at the end of a long-eroded creek bed that now mostly runs dry. The water that ordinarily would flow here instead works its way down into the cave through tiny cracks in the earth and the sandstone below it, carving the tunnels below from limestone deposits created millions of years ago, when the Appalachian Mountains were new and jutted into a shallow inland sea that covered much of the southeast. Eventually, a sinkhole collapsed at the thin intersection of the creek bed and the cave mouth, revealing Mammoth to whoever passed by.

While it's unclear if it was the hunter chasing the bear or the other way round (or if the incident even happened) what is confirmed is that Mammoth Cave was first seen not as a natural wonder, but a manufacturing resource by the man who purchased the land in time for the war of 1812. Dozens of enslaved people were tasked with hauling tons of dirt into huge vats in the cave, where natural lime could leach from the stone walls and eventually be used in the manufacture of saltpeter needed by the young United States' military to make gunpowder.

After the war was over the cave changed hands again and the new owner saw an opportunity to capitalize on affluent travelers' growing interest in outdoor recreation. Enslaved guide Stephen Bishop was the first to create a contemporary map of large swaths of the cave, and the names he gave many of the cave's features are still in use today. Bishop worked with Materson Bransford, Nick Bransford, and Alfred Croghan to lead early tourists past the old earthworks and other unusual businesses that had cropped up in Mammoth Cave, including a mushroom farm and a failed tuberculosis clinic.

The Bransfords and their descendants carried on the guiding trade long after they, Bishop and Croghan were emancipated and well into the 1930s. However, when Mammoth Cave was turned into a national park in the 1940s, the four-generation tradition of Bransfords working in the cave came to a close. The family guides were replaced by park rangers until 2004, when Jerry Bransford joined the NPS staff as the fifth generation of his family to lead tours in Mammoth.

Visiting Mammoth Cave National Park

Unlike many other national parks, you don't need to pay admission or flash your America the Beautiful pass to enter the park or enjoy its trails. The only fees you'll need to pay are if you're camping, staying in the lodge, want to reserve a picnic shelter, or to tour the cave itself. It's wise to book your cave tour at the same time you're making any other reservations in the park, as tours often sell out – especially on weekends, and especially while tour offerings and capacity are limited due to the COVID-19 pandemic. 

The nearest airports are in Nashville, Tennessee (about two hours away) and Lousiville, Kentucky (about an hour and a half away). Bowling Green, Kentucky is about half an hour away – a college town with restaurants, bars, a new brewery , and the vibrant, historically Black Shakerag neighborhood. Scattered nearby throughout central Kentucky are several of the state's famous bourbon distilleries. Just eight miles from Mammoth Cave is Cave City, whose quaint mid-century main street is lined with antique shops. Stop for a beer at The Dive, an atmospheric watering hole full of long-time locals. 

Peak season at Mammoth Cave matches the summers in central Kentucky, which tend to be warm and humid, with highs in the 70s and 80s. Fall and spring are mild and cool, and winters see temperatures hovering in the 30s and 40s. Temperatures inside Mammoth Cave itself, though, are consistently around 54 degrees no matter the time of year or weather. Even when it's raining outside (spring is the wettest month in central Kentucky), Mammoth Cave will be dry, however – at least the part open to visitors.

Activities near Mammoth Cave 

When the COVID-19 pandemic isn't raging, there's usually several cave tours on offer that go to different areas of the cave and showcase different features, from The Rotunda to a formation known as Frozen Niagara. Most of the tours go a quarter of a mile to two miles into the cave, and some involve staircases or some challenging climbs. There are also special holiday-themed events that have been offered in years past, including caroling around Christmastime. Many of the tours depart from one of two outdoor pavilions close to the visitor center before entering Mammoth through the Historic Entrance.

Currently, the Historic Extended tour is what's on offer with limited capacity. This self-guided experience gives you the opportunity to go at your own pace and ask park rangers stationed at notable points along the tour route any questions you might have. Notable features included are the Rotunda, the Methodist Church where actual church services were once held, the historic salt peter mining site, Booth’s Amphitheatre (where the brother of the infamous John Wilkes Booth would recipe passages from Shakespeare), and an eerie formation known as the Giant’s Coffin. 

Tickets for cave tours can be purchased at the Visitor Center or reserved online and cost $25. 

There are a number of hiking trails at Mammoth Cave, but those concentrated around the Visitor Center, campgrounds, and picnic pavilions are well-connected, moderately challenging, and can easily be tackled over the course of a weekend – or even combined into various loops for a day hike. 

Some like the Cedar Sink Trail, Echo River Spring Trail, and River Styx Trail give you a chance to learn more about the unique geography and hydrology of Mammoth Cave. They lead to spots where water either enters or exits the cave system. Water might enter through a sink (think a big natural drain) like the one surrounding the Historic Entrance, or the Cedar Sink on the side of the ridge under which Mammoth is carved. Water also exits the cave on its way to the Green River through several springs where water bubbles out from under rocks or from beneath ponds not far from the main shore.

The Dixon Cave Trail Loop climbs to a separate cave system that used to be connected to Mammoth Cave, but was cut off by a rock collapse similar to that which made Mammoth's entrance accessible. There's a wooden platform built to give hikers a good vantage point of the sink surrounding Dixon Cave's entrance, but you cannot enter the cave. That's to protect Dixon's resident bats, who are at risk from white nose syndrome – a disease that isn't harmful to humans, but can be carried by their shoes and clothing and is a severe threat to bat colonies worldwide.

The Green River Bluffs trail connects to several of these shorter jaunts and offers splendid views of the titular river from high on the bluffs down to the bottom of the ridge where paddle wheel steamboats used to dock at the turn of the last century. One of the easiest loops to create with the Green River Bluffs trail is by connecting to the Heritage Trail for a 2.5 mile hike. The Heritage Trail leads to the historic cemetery where Stephen Bishop is buried, along with several other former cave guides, community members, and the tuberculosis patients treated in Mammoth Cave.

The Echo River Spring Trail has been recently renovated to be more accessible for visitors with disabilities. A portion of the trail has been redesigned as a level, composite boardwalk loop around the Echo River with interpretive features that have tactile elements as well as braille and audio captions. It's part of a longer two mile trail that connects to the Green River Bluffs and Mammoth Sink Hole trails. The new, more accessible section also connects to a recently renovated trailhead that will include a put-in for canoes and kayaks. This trailhead will also be serviced by the Green River Ferry, which has transported vehicles, pedestrians, and cyclists from the south to north shores since 1934. 

Back in the late 19th century, when the Kentucky Caves wars were just starting to heat up and land-owners were competing to see who could tap into the success of Mammoth Cave as a tourist attraction, a railroad was built to bring travelers into the area. It was in service for almost fifty years before the age of the automobile took over and ferry service began at sites like Green River. Today, nine miles of that old rail bed has been turned into a Railroad Trail, an easy to moderate cycling and hiking route that winds through the park.

Staying at Mammoth Cave

There are two primary campgrounds at Mammoth Cave – the main campground and the Maple Springs campground, which caters more to groups, equestrian campers, and those heading into the backcountry. Both feature bathrooms with flush toilets and dumpsters on site. There is also more primitive, tent-only, but still car-accessible camping at Houchin Ferry Campground 15 miles from the visitor center. Backcountry sites are scattered throughout the park, and include some remote island sites only reachable by boat.

You aren't required to have a bear canister in Mammoth Cave National Park, and there aren't bear boxes on site due to low risk. That said, you are advised to keep food in your vehicle overnight to prevent interference from other wildlife. The campsites can accommodate both RV and tent campers, as well as hammock campers thanks to the abundant tree canopy. Due to the threat of the Emerald Ash Borer beetle to trees in the park, campers shouldn't bring firewood with them from neighboring states, but should instead purchase at the camp store or use dead, fallen timber collected on site. 

The Caver’s Camp Store has a range of convenience food and beverage items, including takeaway like pizza, coffee, and biscuits and gravy, as well as some camping supplies and souvenirs. There's a post office on site where you can get stamps for postcards from the gift shop or pick up a package. There are also hot showers available. WiFi is available in the Visitor Center and  in the Lodge, but cellphone service is limited throughout the park.

The Mammoth Cave Lodge

The Mammoth Cave Lodge is made up of several different buildings ranging from hotel-style rooms in a 1960s modernist structure to small cottages to an ADA-accessible motor-lodge style space. There are two eateries on site, including a sit-down restaurant called the Green River Grill  and the more casual cafeteria-style Spelunkers Café & Ice Cream Parlor, which has takeaway sandwiches, chips and drinks, as well as hot items like burgers on offer. Both make extensive use of local products from Kentucky vendors on their menus.

While the Visitors Center was built in 2012 in a contemporary style that refers back to classic "parksitecture" and is powered by banks of solar panels, recent renovations to the Lodge buildings weren't started until 2017. Thus far, the updates have focused on making Mammoth Cave National Park more environmentally friendly, with outdoor LED lighting, upgrades to waste water treatment, and refreshes to the room amenities, as well as expansions of the concessionaire and gift shops. Since 2019, has been continued expansion of the lodge with new construction, too, as well as continued renovation of the existing rooms.

Is Mammoth Cave Worth Visiting?

Yes, Mammoth Cave is worth visiting! Immersing yourself in the park’s stunning landscapes, from lush forests to picturesque river valleys to the famous cave itself, is a family bucket list experience.

Mammoth Cave National Park offers an experience unlike any other National Park east of the Mississippi River. From the moment you step foot into the cave, you’ll be transported to a world of natural wonder and beauty that will leave you awestruck. Mammoth Cave makes a great stop on a family cross-country road trip .

Mammoth Cave is an incredible feat of nature, with massive chambers, intricate passageways, and bizarre formations that have been sculpted by millions of years of water erosion and geologic activity. But beyond its sheer size and beauty, Mammoth Cave also has a rich history that is woven into the fabric of American culture.

In addition to the cave tours, Mammoth Cave National Park has a variety of outdoor activities to enjoy. We love hiking and biking as a family and there are plenty of trails to explore here. The Green River also provides opportunities for canoeing, kayaking, and fishing. And for those who prefer to stay indoors, the park offers a variety of ranger-led programs and exhibits.

When is the Best Time to Visit Mammoth Cave?

The best time to visit Mammoth Cave National Park is during the spring and fall seasons, specifically from April to June and September to October. We visited in September, right after school started, and that seemed like the perfect time to come to Mammoth Cave! During these times, the weather is generally pleasant, with milder temperatures and lower humidity compared to the hot and humid summer months. 

The park’s natural beauty flourishes during spring, as wildflowers bloom and the surrounding landscape comes alive with vibrant colors. Fall offers a picturesque spectacle with the changing leaves, creating a breathtaking backdrop for exploration.

Visiting during these seasons also ensures a more comfortable experience while exploring the cave system. The cave’s temperature remains constant at around 54 degrees Fahrenheit (12 degrees Celsius) throughout the year, making it a refreshing escape from both the summer heat and winter chill.

More importantly, spring and fall attract fewer crowds compared to the peak summer season. This means shorter lines for the best Mammoth Cave tour, easier access to hiking trails, and a quieter overall ambiance.

Mammoth Cave National Park is a popular destination year-round, and each season offers its own unique charm. However, for those seeking pleasant weather, beautiful scenery, and a more relaxed atmosphere, spring and fall are the ideal times to experience the park’s wonders at their best.

The Best Mammoth Cave Tours

Tours are required when visiting Mammoth Cave. They offer visitors the opportunity to learn about the cave’s history and geology from knowledgeable rangers who will guide you through the cave system and point out interesting features along the way. There is one option for a short, self-guided tour of the cave, which is only offered in the summer. All other tours are guided tours.

There are a variety of tours available to suit every interest and level of ability, from easy strolls through well-lit sections of the cave to more challenging explorations of remote areas that require crawling and climbing. The cost of most tours ranges from $10 – $30 a person. Many cave tours require a short bus ride to and from the visitor center to the cave entrance.

We took the Domes and Dripstone Tour which was a perfect fit for us. There are quite a few stairs and some tight spaces, but we were up for the adventure. The views were incredible and not something I will soon forget. 

No matter which tour you choose, you’ll be treated to a one-of-a-kind experience that you will never forget. And with so much to see and do at Mammoth Cave National Park, you’ll want to plan a return trip before you even leave.

The Adventures of Trail & Hitch

Two geeks, two cats in an airstream., best cave tours of mammoth cave.

Travel Adventures , Washington DC - Trail (Anne) - July 10, 2021

After writing a lengthy article on “ How to Visit Mammoth Cave National Park ,” I feel that I should make suggestions as to which cave tours to go on. We spent two weeks in the Mammoth Cave area and got to go on many of the major tours.

Historic Tour or River Styx Tour

I enjoyed the Historic Tour the most, out of all that we attended. We started at the Lodge Rotunda for a quick orientation before hiking down to the Historic Entrance. Our rangers guided us at an even pace, stopping every so often to tell a story or to point out a classic Mammoth Cave landmarks, which were visited by historical figures of the 1800s and early 1900s.

Highlights include crossing bridges over both Sidesaddle Pit and Bottomless Pit, squeezing through Fat Man’s Misery, crouching down into Tall Man’s Agony, and finally climbing up The Tower to view Ruins of Karnack and the great Mammoth Dome. Overall a fantastic tour featuring both history and cave decoration viewing.

At the time, I really wanted to take the River Styx Tour, which also includes the Historic Tour but then takes a side path down to an underground river. As much as I love history, I would have also enjoyed learning about the geology of Mammoth Cave. Sadly during our visit NPS closed the River Styx area due to a recent flood.

Up The Tower to Mammoth Dome

Violet City Lantern Tour

If you love history and wish to explore Mammoth Cave as they did in the past, then Violet City Lantern Tour is perfect.

A German mining engineer by the name of Max Kämper discovered a passage in 1918, along with his cave guide, Edwin Bishop. Together they crawled through a narrow passageway connecting Ultima Thule and Kämper’s Hall, which he named after himself. Today that passage area is known as Violet City, named after the cave owner’s wife, Violet Blair Janin.

From the shelters outside the visitor center, our ranger gave out lanterns before hiking down to the Historic Entrance. We passed landmarks we’ve seen on other shorter tours, such as the Rotunda, Broadway Avenue, and Giant’s Coffin.

Along the Main Cave just past Giant’s Coffin, we ventured into new territory. We saw the remains of old underground huts which housed Turburciolsis patients. Further down, we enter an underground canyon known as the Star Chamber, where the roof seems to rise about 20 or 30 feet above the ground and mimics a starry night. At a place called the Cataracts, we passed a subterranean waterfall pouring out of a hole in the ceiling.

Violet City Lantern Tours

At one point, after passing a 2000-year-old petroglyph, we end up at a spot where a 1935 work crew found the mummified remains of a Palio-Indian. Nicknamed “Lost John,” the National Park Service considered the 5-foot-3-inch man a major archaeological find and exhibited his body until 1976 when federal law prohibited the display of Indian human remains. The Rangers re-interred Lost John in a hidden location near where he was found.

Violet CIty

Near Ultima Thule, we climbed up and through the Grand Portal, a 60-foot wide and 50-foot high passage leading to Kämper’s Hall and Violet City. Sadly our lamps lacked sufficiency to illuminate the huge hall, but we saw dripstone formations, stalactites hanging down from the dark, and curtains of calcite. If you ask nicely, maybe your ranger will let you shine a flashlight on the Marble Temple, which is a flowstone wall decorated by stalactites on either side. We also passed several domes and Bishop’s Pit before climbing up and out a man-made tunnel to Violet City’s Exit.

Important Cave Touring Tip: Do not tailgate the person before. Since the cave path is dark and only lit by lanterns, keep an eye out for when the person before you stops or slows down. If you are a fast walker, I suggest going to the back of the group. That way you can pause longer, and catch-up quickly. If you are slow, move up front with the ranger who sets the pace for the group.

We pause for a rest and a history lesson

Grand Avenue Tour

Grand Avenue demands endurance from any hiker, but you’ll be rewarded with fascinating cave decorations and a wealth of stories as told by your ranger. Thankfully, our rangers were kind enough to go at an even pace and provide frequent stops along the way. We enjoyed this tour for its exceptional overview of the size and intricacy of the Mammoth Cave System.

After our orientation at the visitor center shelters, we took a short bus trip to the Carmicheal Entrance. This man-made passageway goes downward and into an area known as Cleaveland Avenue. The low ceiling tunnel felt long and unending, especially in low light. Here the walls showed evidence of an underground river now long gone.

Snowball room in Mammoth Cave – courtesy of NPS.gov

Snowballs & Grapes

After about a mile, we ended up in the Snowball Room. In this cavern, the ceiling is dotted with mineral lumps similar to snowballs in shape. These gypsum “blisters” formed as the mineral pushed outward into the cave by more gypsum forming in a layer just behind the surface. Beneath the faux snow roof, rows of tables stand ready to serve those who need a break. Our ranger tells us during certain times of the year, the Snowball room serves food. Just passed the Snowball Room, we entered an area called Mary’s Vineyard. Here the cave displays grapelike formations in the limestone deposits on the cave ceiling. As water carrying calcium carbonite drops downward, the water precipitates clusters of minerals, suspended in grape-like formations from the ceiling.

Gypsum Flowers & Flowstones

Our ranger then lead us to steep-walled Boone’s Avenue, a good example of one of the cave passages formed by water. Along the walls, there is past evidence of fast moving water, working its way down along a mild slope into deeper portions the cave. Through the winding channels, we arrived at Kentucky Avenue where the most fantastic gypsum crystals and needles can be found. Then at Grand Central Station, where at least five passages converge, we pause for our ranger to explain how this intersection of joints came to be. Our group then moved into the upper cave levels, where we finally got to see a fascinating variety of dripstone and flowstone formations such as the Frozen Niagara, Drapery Room, and Onyx Colonnade. All of it made a fine reward for the longest trip in Mammoth Cave.

Gypsum Flowers on Kentucky Avenue

Great Onyx Cave Lantern Tour

In 1915, Edmund Turner discovered Great Onyx Cave just after agreeing to be a shareowner with Flint Ridge landowner L. P. Edwards. As soon as Edwards agreed, Turner showed him where to dig, and resulted in the Great Onyx Cave, so named because of its cave onyx formations. Together, Turner continued to explore the cave while Edwards rushed to commercialize it.

At first, the owners of Great Onyx Cave refused to sell their land when the federal government in the 1930s, when it was making land purchases for the formation of Mammoth Cave National Park. When the National Park was established in 1941, Great Onyx Cave remained a privately held “island” within the Park’s borders. In January 1961, the owners finally sold Great Onyx Cave to the National Park Service. Today, you can take tours to the Great Onyx Cave depending on the season.

Great Onyx Cave Entrance

Despite search efforts, cave explorers have yet to find a connection between Great Onyx Cave to the rest of the Flint Ridge Cave System and Mammoth Cave. In fact, passages in the Flint Ridge Cave System pass beneath surveyed passages of Great Onyx Cave. During the cave’s commercialization, the owners most likely piled rocks and sand against the walls during their trail construction. During construction, it’s possible that they blocked off passages which might have connected to Mammoth Cave.

Although there are 8 mapped miles of Great Onyx Cave, you’ll only see a fraction of it. For those who love cave decorations, Great Onyx Cave is the tour you’ll want. Sadly, you’ll have to examine this geologic attraction by lantern light, putting a shadowy backdrop for an amazing yet abundant volume of dripstone gypsum, helictite formations, and travertine flowstones.

Great Onyx Cave

Mammoth Self-Guided Discovery Tour

If you have only time for a short visit to Mammoth Caves, I suggest the self-paced Discovery Tour. They usually offer this tour during the summer months and on weekends during spring and fall. You’ll visit the Rotunda, one of the largest rooms in the cave, and explore a Houchins Narrows and Audobon Avenue. Visitors will learn about 19th-century saltpeter mining operations and the geologic origins of Mammoth Cave from one of the many rangers stationed about the cave. Sadly you cannot reserve this tour online, the NPS only sells tickets daily and on a first-come-first-served base.

Saltpeter Sites

Wild Cave Tour

If you are up for an adventure, take the “extremely strenuous” Wild Cave Tour. They offer this tour daily in the summertime for adults only. After you pass the “42-inch-diameter-narrow-fit” test, they go through a detailed orientation on gear and safety. You’ll get overalls, gloves, and a hardhat with a headlamp. You’ll be crawling a majority of the 5-miles that this tour covers, so it’s not for the faint-hearted. At one section, you must traverse a slippery ledge while leaning across the chasm to put your hands on the far wall to balance yourself, then sidestep down the slope. Important: If you’re don’t like heights, super enclosed spaces or darkness, do not go on the Wild Cave Tour! Those who are relatively fit, and little to no fears of such things, will thoroughly enjoy this amazing experience.

We’re planning a trip to Mammoth Cave in early April. We love the idea of the violet city lantern tour. However I’m a little claustrophobic and wanted to ensure that the trails, paths, etc had plenty of overhead headspace. Please advise. Thanks

I would advise against it. There are a few places where we had to duck and squeeze through passages. If you want a cave tour that has plenty of overhead space I suggest visiting Carlsbad Caverns National Park in New Mexico.

You can’t help NOT love the park & caves! Enjoy them both & treat them with respect- for all our families& friends-You won’t regret it! Thanks-A Friend From Michigan! You all are GREAT!

I know! You’re totally right: respect nature — especially if you wish them to last through the generations to come. National parks are a fantastic legacy that America has to offer.

Amazing pictures and wonderful overview of the tours.

Thanks! Spending two weeks at Mammoth allowed us to take nearly all the tours. With the exception of a few tours only run certain seasons.

Very, very cool. I love that the NPS reinterred Lost John, too. I think they’ve done a pretty good job handling things like that.

I think everyone can learn a thing or two about the graceful way rangers respect historical artifacts and nature. I really admire them for that.
