The cavern was created by decades of limestone mining to supply the construction of the Louisville highway system.
It is one of the largest man-made caverns in the United States, containing 17 miles of passageways.
The mountain bike park features over 45 individual trails tailored for various skill levels, ranging from beginner to expert.
The facility is capable of supporting heavy surface traffic, including industrial trucks, due to the thickness of the rock pillars left behind during mining.
The underground light display, Lights Under Louisville, utilizes over 4,000,000 points of light during the holiday season.
Louisville Mega Cavern is a man-made subterranean adventure park located within a 100-acre limestone mine that operated until the 1970s. The facility features the world's only fully underground aerial ropes course and a permanent subterranean mountain bike park spanning over 320,000 square feet. Visitors can access the cavern via guided tram tours that explain the geology and history of the blast-mining operations. The zip line course consists of six underground lines, including a dual racing zip and challenge bridges. The cavern maintains a constant year-round temperature of approximately 58 degrees Fahrenheit regardless of external weather. It serves as an active event space for seasonal light displays and educational tours regarding karst topography.
The elevated suspension bridges on the aerial ropes course provide a unique perspective of the vast, lighted cavern ceiling.
Wear closed-toe, athletic shoes to participate in the bike park or ropes courses.
Bring a light jacket or long-sleeved shirt, as the cave remains chilly even in the summer.
Book reservations for zip lining and biking well in advance, as these activities have strict capacity limits.
Do not attempt to walk the bike trails on foot, as they are designated strictly for cyclists.
Open year-round, though specific adventure activities may occasionally close for private maintenance or corporate events.
Helmets are mandatory for all bike park and ropes course activities and are provided on-site.
