Louisville Mega Cavern
A huge underground space converted from an abandoned limestone mine, with tram tours, underground zip lines, and a rope course.
The Louisville Mega Cavern is an artificial cavern left from limestone mining in the 20th century. It covers about 40 hectares and lies beneath the Louisville Zoo, and is said to be the largest “building” in Kentucky. Today it offers historical tram tours, multi-stage underground zip lines, rope challenge courses, and an underground bike park. In winter, the “Underground Christmas Lights” event lets you drive through a field of light displays inside the cave, which is popular with families. The cavern stays at a constant temperature year-round, so bring a jacket and sneakers. Zip line sessions must be booked in advance.
