Beneath the Black Hills of South Dakota is the intriguing underground world of Jewel Cave. With over 202 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. 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.
