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.
