Create an itinerary including Mammoth Cave
Winding through the ground for nearly 652 km (405 mi), the World Heritage Site Mammoth Cave claims the title, by a significant margin, of longest cave system on the planet. You won’t be the only one surveying the cave. Exploration continues constantly, so the official length of the system continues to grow with the discovery of new passageways, tunnels, and caverns. In addition to thousands of bats, the subterranean labyrinth possesses a nearly 6,000-year history of humans, beginning with pre-Columbian natives of the region. The National Park Service runs multiple versions of its cave tours of varying length, which can take you on popular paths or on more adventurous routes that require some tight squeezes and nimbleness. Watch for geological mineral and rock formations scattered throughout the cave.

  • Astonishing place. A must-to-visit for everyone which is nearby. I suggest to get the long 700m walk instead of the 200m one at the end of the tour.

  • Mammoth Cave is just that- a big cave. And fairly boring. Worth visiting once but not again. For me, caverns with interesting formations are much more worth the time and effort to visit. Carlsbad...

  • I had not been in many years. The visitor center is much nicer now. We booked the Extended Historic Tour. The tickets are easily bought online. We gathered at a nearby shelter where our guide told us a bit about the tour and what it would entail. We then walked to the cave entrance. Inside is quite an amazing experience. With the Extended tour, you get to see remnants of the huts where TB patients were kept in attempt to treat their disease. Our tour guide was fabulous in telling us about the cave an its history. The tour is a little over two miles and two hours. There are quite a few steps/stairs. However, there are several breaks (with benches for sitting) where the tour guide talks about the cave. There are other tours available to match your level of fitness and what you might to see there. Highly recommended.
  • Tour was nice. Well organized, but the caves didn't have a lot of natural formations. One part of our tour did, but the rest was a long walk through the cave. We took the Grand Avenue tour, very challenging for my wife and I (fairly decent shape for approaching 60). If you are here you kinda have to check out mammoth caves, but we enjoyed some one of the local privately owned caves much more. Crystal Onyx Caves where amazing. See my review on Google.
  • This was a great National Park. Quite large, but the sites are spacious and somewhat private. There are no amenities, such as water or electricity, so generators might be nice. We did well with just boondocks g and a pumpkin at the end. Very nice bathrooms everywhere. The small camp store is well stocked with basics and there was a laundry and post office. We took two tours, one we bussed to, and one was a walk to the original entrance and inside. Both were ranger led and our rangers were excellent and very well informed. So worthwhile. A great visitors center with gifts galore and it is here where you arrange your tours. Great experience.
  • This is a very very beautiful, calm, family friendly park. We took the Mammoth Cave tour and it was a fabulous experience! Make sure you check ahead about times and you may want to book ahead. The tour guides (they refer to themselves as rangers, but they are definitely not full force Park rangers.. more like Yogi Bear rangers) are very knowledgeable and give useful information throughout the tour. Unfortunately there were some rowdy small children on our tour, so that impeded the enjoyment a bit unfortunately... so be mindful of the crowd you are taking the tour with. There are all kinds of Hands-On experiences to enjoy while waiting for tours to start.. as well as overpriced gift shops. Food concessions, hiking trails, picnic areas,.. just about everything you can think of is here. There are even cabin rentals, a hotel and a post office! Be mindful that the visitor center closes fairly early evening and they also close their restrooms. I would definitely plan to spend a few days but also a day trip is worth it if you are in the area. We do not have an rv, but I can say that there were dumb spots and ample parking spaces.
  • You can get tickets ahead of time or at the visitor's center. Be sure you know which type of tour you want and what your body can handle. The walking tour includes some low spots, narrow squeezes, and lots of steps. If you need to walk slower, stay up front with the tour guide. Our tour guides were great! We learned a lot. They answered all the questions and gave great recommendations. The visitor's center has so much information. Check it out while you're waiting for your tour. We've been to many caves and while they're all unique, this has been my favorite. Bathrooms were clean. Snack bar was limited.
