About Louisville Mega Cavern

Unveiling a hidden world beneath the city of Louisville, Kentucky, Louisville Mega Cavern boasts the title of the largest man-made cave system in North America. Once a working limestone mine, this 100-acre marvel has transformed into a premier destination for adventure and exploration.

Louisville Mega Cavern caters to a variety of interests. Thrill-seekers can soar through the caverns on the world’s only fully underground zip line course, Mega Zips. History buffs can delve into the cavern’s fascinating past on a narrated tram tour, Mega Tram. For those seeking a more in-depth exploration, Mega Quest walking tours reveal hidden passages and geological wonders.

About Louisville Mega Cavern

A testament to nature and human ingenuity, the Louisville Mega Cavern stands as a colossal landmark beneath the bustling streets of Louisville, Kentucky. Originally named Louisville Crushed Stone, limestone miners systematically carved out the man-made cavern for four decades. By 1989, several forward-thinking private investors realized that this massive underground secret could serve a new purpose: it would be turned into Kentucky’s premier environmentally conscious recycling center.

This high-security commercial storage facility does double duty as a prime tourist destination for visitors wanting to view the subterranean marvel themselves. Now, the cavern hosts 4,000,000 square feet of offices, storage spaces, and tourist activities. With consistent, comfortable temperatures and its dual zoning status as both ground and building, the Louisville Mega Cavern is a secure, safe, and beautiful location for guests of all ages.
