Watch Pro Cyclists Get Big Air in the World’s Largest Indoor Bike Park

Deep beneath Louisville, Kentucky, mountain bike pros Aaron Chase, Adam Hauck, and Reed Boggs hit the biggest lines in the world’s largest indoor bike park, the Mega Cavern. What was once an abandoned mine was transformed into a 320,000-square-foot biking playhouse that includes 12 miles worth of trails with jump lines, pump tracks, dual slalom, BMX, and cross-country singletrack.

The bike park is just one aspect of the Mega Cavern. Other activities include zip-lining, ropes challenge courses, and a historic tram car tour. The 100-acre cavern is considered a building — the largest in the state of Kentucky, in fact. The temperature is always a comfortable 60 degrees, so everyone can enjoy the Mega Cavern year-round.
