Badlands National Park (Lakota: Makȟóšiča) is an American national park located in southwestern South Dakota. The park protects 242,756 acres (379.3 sq mi; 982.4 km2) of sharply eroded buttes and pinnacles, along with the largest undisturbed mixed grass prairie in the United States. The National Park Service manages the park, with the South Unit being co-managed with the Oglala Lakota tribe. The White River Badlands have developed an international reputation as a fossil-rich area. They contain the richest deposits of Oligocene mammals known, providing a glimpse of life in the area 33 million years ago.
For those interested in front-country camping, the park offers two official campgrounds. The Cedar Pass Campground is a paid campground with 96 sites total, some designated for RV camping with electric hookups. Sage Creek Campground is a free, first-come first-serve campground with 22 sites. Motor homes, pull behind trailers, and other recreational vehicles greater than 18 feet in length are prohibited. For those seeking a more rugged camping experience, back-country camping is also available in the park. Back-country camping is permitted anywhere in the park as long as it is 0.5 miles from a road or trail and is not visible from a trail or roadway.
