Description

Jewel Cave National Monument contains Jewel Cave, currently the third longest cave in the world, with 200.3 miles of mapped passageways. The cave is known to be a 'breathing cave,' which means air enters or exits the cave with changes in atmospheric pressure from day to night or due to changes in the weather. The Park Service offers three tours of the cave: the scenic tour, which is a half-mile loop through a paved and lighted central portion of the cave accessible by elevator; the historic tour, which is a candlelight tour through the earliest-discovered part of the cave; and a wild caving tour, which passes through an undeveloped part of the cave near the scenic loop.
