Why Wind Cave National Park
Wind Cave National Park is located in western South Dakota, situated 10 miles north of the town of Hot Springs in Custer County. Established in 1903 by President Theodore Roosevelt as the sixth national park in the United States, it holds the distinction of being the first cave in the world to receive national park status. Below ground, it features the densest cave network on Earth by passage volume per cubic mile and ranks among the longest explored cave systems globally, containing over 168 miles of mapped subterranean pathways.
The underground environment is internationally renowned for its rare mineral formations, containing roughly 95 percent of the world's discovered boxwork—a distinctive pattern of intersecting calcite fins—alongside frostwork, cave popcorn, helictite bushes, moonmilk, and calcite rafts. Wind Cave is famously recognized as a breathing cave. Air continually shifts in and out of its openings to balance internal atmospheric pressure with changing external barometric conditions, producing noticeable winds at the surface when weather patterns shift.
Indigenous peoples, including the Lakota and Cheyenne, were long aware of the site and utilized the surrounding region for winter camps and hunting. In Lakota tradition, the cave is known as Washun Niya and held as a sacred site marking the emergence of the first human from the underworld. Euro-American settlers documented the cave in 1881 after observing air rushing from a small ground opening. The McDonald family subsequently explored the passages and established guided candlelight tours for visitors by 1892.
Above the surface, the park protects the largest remaining natural mixed-grass prairie in the United States, complemented by ponderosa pine woodlands. It provides habitat for diverse wildlife, including elk, prairie dogs, pronghorn, coyotes, and endangered species such as the black-footed ferret and whooping crane. Notably, the park preserves a free-roaming, genetically pure, and brucellosis-free bison herd, which is one of only four such herds on public lands in North America.
Visitors can explore 30 miles of surface hiking trails or travel along park roads, with the southern terminus of the South Dakota Centennial Trail located within the park boundary. The park visitor center houses three exhibit rooms detailing cave geology, natural history, and historic Civilian Conservation Corps projects. Located roughly 1.25 miles from the visitor center, Elk Mountain Campground offers 75 campsites in a ponderosa pine forest, operating year-round with summer campfire events and reduced winter services.
