Jewel Cave Information
If your travels take you to South Dakota, take the time to visit Jewel Cave National Monument, which is 13 miles west of the town of Custer in the Black Hills. Jewel Cave is the second longest cave in the world, with 145 miles of passageways. The cave takes its name from its shiny calcite crystal formations. In addition to the caves themselves, visitors can explore above ground via many trails and walks.

Guided Cave Hikes

All cave hikes are led by National Park Services Rangers. The average temperature in the caves is 49 degrees F. Bring warm clothes for layering. No food, drink or tobacco is allowed in the caves.



While cameras are allowed, even encouraged, tripods are not allowed in the caves. Flash photography is permitted while in the caves.

Above Ground

Located in a 1,279 acre Ponderosa Pine forest, Jewel Cave National Monument is also home to 393 different plants and wildflowers, including more than 120 different species of birds. Bird lists are available at the visitors center. Hikers can explore many underground trails including "Hell's Canyon," "A Walk On the Roof" and "The Canyons."

No Fee Ranger Programs

Free talks on wildlife ecology, indigenous plants, the Jasper Fire of August 24, 2000 and more are led by Rangers daily.
