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.

  • 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.
