Mammoth Cave National Park
Home to the longest cave system on earth, Mammoth Cave National Park has more than 400 miles of surveyed passageways. Mammoth is at least three times longer than any other known cave, with vast interior cathedrals, bottomless pits and strange, undulating rock formations. Guided tours delve into the spookily beautiful underworld.
