    Discover One of the Last Frontiers in the World Immerse yourself within the third longest cave in the world. With over 208 miles of mapped and surveyed passages, this underground wilderness appeals to human curiosity. Its splendor is revealed through fragile formations and glimpses of brilliant color. Its maze of passages lure explorers, and its scientific wealth remains a mystery. This resource is truly a jewel in the National Park Service. You must join a ranger-guided tour to enter Jewel Cave. Advance reservations are recommended. The surface areas do not require a reservation and consist of a ponderosa pine forest, interspersed with open meadows and fire-scarred landscapes. Lithograph and Hell Canyons offer rocky terrain, with cliffs, shelter caves, and spectacular views of the southern Black Hills. Two hiking trails are available, along with numerous picnic areas at the visitor center and Jewel Cave Historic Cabin Area. Surface recreation is available year-round, with snowshoes being available for loan during the off-season. Wildlife in the monument consist of elk, white-tail deer, mule deer, bighorn sheep, coyotes, wild turkeys, birds of prey, and numerous species of songbirds. The diversity of flora is prevalent during the spring and early summer seasons. The visitor center provides engaging and interactive displays, and the park film shares the natural and cultural history of the monument.
