Mega Cavern: A Whole Other World Beneath the City
Can you name the biggest building in Kentucky? Most visitors from out-of-state are surprised to learn the answer: Mega Cavern. Technically classified as a building because of its support structures, Mega Cavern is actually a 4-million-square-foot former limestone quarry right here in Louisville. Though this massive underground cavern, which also served as a fallout shelter during the Cold War, hasn’t been mined since the 1970s, it remains a vibrant part of life in Louisville. With some 45 cycling trails to choose from, it’s now the world’s largest underground bicycling park. In addition to the bike trails, Mega Zips offers visitors 6 thrilling ziplines and 2 challenge bridges for 2-hours of heart-racing adventure. You can also try out the accompanying ropes course, Mega Quest, which is the only fully underground ropes course in the world. For a more laid-back subterranean experience, Mega Tram offers riders magnificent views of more than 17 miles of dazzling passageways, and around Christmastime, you can drive your car right into the cavern for “Lights Under Louisville,” a one-of-a-kind holiday lights show that’s not to be missed.
