Louisville Mega Cavern, Louisville

4.6
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).
