#1 of 10 in Things to do in Mammoth Cave National Park
Winding through the ground for nearly 652 km (405 mi), the World Heritage Site Mammoth Cave National Park 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.

  • Your tour guide can make or break this experience, I believe, while some of the cave tours are much more interesting than others. Over two days last week we did three different tours: Onyx Cave Lanter...  more »
  • I'm going to buck the trend on this one. We were lucky to get in one of the "historic" tours. Book in advance or you will probably end up with only the self guided tour which limits what you see. I'm giving 3 stars because 100 people is too many to have in a tour group. Unless you were one of the lucky 25 people in the front you miss half of what the ranger said. We had just come from Carlsbad Caverns in Arizona where they ask you to be quiet and whisper while in the cave. With a group this large there is always someone talking and often it was hard to hear the ranger. I wouldn't take a child under age 6 as they get bored. The park is definitely a 5 star with lots of good hikes and other things to do. Beautiful but until they figure out how to make smaller groups I have to give the tour a 3 star rating. One more thought, I am claustrophobic and had reservations about going on the tour. I had no problem whatsoever. The few times we were in small areas we moved through them so fast you don't have time to get scared.
  • Awesome park! So glad we made the decision to stop when we were passing by on our way down south. Decided to come back and make a whole trip of visiting this with the kids. Pretty incredible! Largest cave system in the world! Over 400 miles of caves, which is pretty insane. We went on a tour that took us pretty deep into the earth, which the kids thought was amazing. We must have went down a good 15+ flights of stairs into the ground. My children loved the tour, but my 8yr old son might remember getting deputized as an honorary Jr. Park Ranger the most. Also, very nice guide noticed my son wearing a hearing aid and asked if we were aware of the disability program with national parks. Turns out if you have a disability, you get a FREE pass to ANY national park in the US. And that means the people with you (parents and passengers) get free admission as well. My wife and son both have hearing loss in one ear, so both were given the free admission cards. Just a heads up in case you were not aware, as we were.
