One of the longest caves in the world

Beneath the Black Hills of South Dakota is the intriguing underground world of Jewel Cave. With 173 miles of explored passageways, Jewel Cave ranks as one of the longest caves in the world. The cave was discovered at the turn of the century by brothers passing through Hell Canyon.

With over 180 miles of documented trails, this underground environment can satiate even the most curious of humans. Brilliant color and fragile rocks reveal an amazing ecosystem not visible anywhere else. The third longest cave in the world has much to offer to a wide range of those interested in its natural glory. This resource is truly a jewel in the National Park Service.

Guided cave tours provide opportunities for viewing this pristine cave system filed with calcite crystals and other wonders such as stalactites, stalagmites, draperies, frostwork, boxwork, flowstone and hydromagnesite balloons.
