Louisville Mega Cavern, Louisville

Must see · Cave · Nature / Park
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).

  • Me n my family n friends visit this place first time. It really amazing. We all enjoy it. Due to busy hours we have to go early to the event. All the employees are helpful. God bless all of them. God bless USA.
  • Excellent light show. Line was minimal the night we went. Would recommend to anyone. Displays were mostly the same as last year it seemed. I'd recommend going every 3 years or so vs each year in that case.
  • We went to the day time light show in the tram. It was great. The lights and display were beautiful and the staff was over the top fabulous. The young lady driving was funny and friendly and the staff helping on and off the tram were silly and fun too. They made it a super memory that we will remember for years.
  • Had an absolutely great time here. We did the bike tour and our tour guide Zack was amazing. He knew so much about the mine and you could tell that he enjoys his job. Definitely worth the trip!
  • Went there with out of town family to see Lights Under Louisville. The light show was very well put together and flowed very smoothly. The only downside was the long wait in parking lots to get there. After getting to the front I could see why they set it up the way they did for the volume of cars. For us first timers it would have been nice to have signage as to how long the wait is. The wait in the lots was longer than the light show was itself. But I still enjoyed it.
