Create an itinerary including Louisville Mega Cavern
Discover the underground world of Louisville Mega Cavern, once a bomb shelter capable of housing nearly 50,000 people. Today, the cavern features the world's only underground zipline course that allows you to plunge off 20 m (70 ft) cliffs into a pit of darkness. If jumping into complete blackness isn't your thing, take a tram tour of the cavern's many passages. The tram stops at a large worm farm, where insects consume trash in order to produce fertilizer. Be sure to dress appropriately--the cavern is 30 m (100 ft) below the city, and temperatures rarely rise above 13 C (56 F).

  • Anna, the tour guide, was very knowledgeable about the history and current status of the Mega Cavern. She drove the tram well and stopped to show us about the cavern.

  • Super fun experience! The guides did such a nice job. I always felt safe and knew what to expect. It was chilly in the caverns. Long sleeves are a must. Pants are preferable to shorts and close toed shoes are required. Lucy and Annie were great guides. They made us feel comfortable and had a great sense of humor.
  • Definitely unique and one of a kind adventure. We did the zip line. Our guides, Abby and Austin were great. Lots of fun but very knowledgeable about comfort and safety of guests. It probably would’ve been more fun if I was younger and in better shape, as my technique and body positioning not conducive to maximum speed. Would’ve given 5 stars but at $100 dollars per adult, I found it a bit pricey for 2 hours of entertainment.
  • We had such a good time! I was honestly more nervous than I expected on the zipline ledges and they made us very comfortable. We had Jerry and Hayley and Claire along for training I think. Dont let their baby faces trick you, they know what they're doing! And they do it all for you. Hayley even discreetly warned me about things that might make me nervous, and that was seriously so sweet. She made sure no one else noticed and walked me through it. Jerry and Hayley were both really entertaining and knowledgeable. And Claire was so engaging for someone in training! Great conversation all around. Definitely don't miss this place! They also have walking and tram tours in addition to the zipline. Great time all around.
  • The lights and the music are fun and are nicely done. I was really impressed with how they line up all the cars and then start the line through the cave. The line consistently moves and you're never just stopped/stuck so that nice. It was run really efficiently. I gave 4 stars instead of 5 because it is a really short experience, overall I think it only took us 20 minutes to drive through.
  • Our guide was fun and made the tour even more fun. It was neat to see the space under our feet. Some of the holiday lights are still in place and that was cool, gave us a little taste and invited us to come back. They were preparing for a winter storm and there were several huge trucks picking up salt that is being stored down there (which I had no idea). Very neat.
