Mammoth Cave, Mammoth Cave National Park

Must see · World heritage site · Cave · Nature / Park
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.

  • This is a fabulous National Park to visit!! I live in Indy and spent Labor Day weekend with my grown grandchildren who live in Nashville, TN. The park is only an hour and a half away and we decided...  more »
  • I suggest booking a tour if you're able to because the rangers are so knowledgeable and the history of this beautiful place is fascinating. We were traveling with little kids so we did the accessible tour which is well lit but also shorter so when your kid asks, "how much longer is this?" you can say, "not to much longer" and have it be the truth! If we'd been traveling without kids, we would've done a longer tour. There is a self guided tour which we also did and that has 160 steps coming out of it so not too bad comparatively but if you're a step tracker, maybe you can earn a badge coming out on that climb! The self guided tour is one that can take as long as you want it to really. It's beautiful inside the cave and takes a moment for eyes to adjust. There were rangers everywhere in the park which was nice to see. If a question ever came up, there was always someone nearby with an answer. As it turns out, bats do not listen to Kiss inside the cave. Ranger Stephen gently delivered that news to our 5 yr-old. Also, we did not see Bigfoot.
  • What a great National Park! Enjoyed the discovery tour very much. Tour guide/park ranger did a great job. If we had time for the 6.5 hour tour I would definitely do it. You feel the history walking through the dim lit caves, knowing how many before you walked through them. If your in the area and have a few hours stop in for the tour. I recommend booking in advance or coming at 8:00am to reserve a spot.
  • It a beautiful place to stop by and explore, especially if you know the map and see all the hidden history. The cave is definitely giant, but it's not as pretty as the smaller caves around. If you stop by, definitely explore above ground too!
  • Its a great experience for anyone! They have multiple cave tours in a beautiful area. The park rangers are incredibly helpful and funny at the stories they tell down in the caves.
  • It was a great experience! Our tour guide was very knowledgeable about the history and geography of the caves. The caves are very diverse so each your shows very different types of features. The trails above ground aren't the best but that's not the point of this national park.
