Louisville is home to one of the largest caverns in the United States – so large, it has been dubbed the “Mega” Cavern. Originally a massive limestone quarry that was blasted by miners for 42 years in the 20th century, it’s now used as an environmentally-conscious attraction that measures approximately 100 acres. Attractions include: Mega Zips, where trained tour guides will lead you on a two hour thrilling adventure, Mega Tram, where the Historic Tram Tour will take you on an underground adventure rich in history, geology, mining, recycling, and green building technology, Mega Walking, a 90-minute excusing through about 60% of the Mega Cavern, and Mega Quest, the fully underground aerial rope challenge course!
