The Wind Cave National Park Visitor Center serves as the gateway to exploring the park's unique underground and surface features. Visitors can obtain information, maps, and backcountry permits, and purchase passes for cave tours, which depart from here. The center features exhibits on the park's geology, wildlife, and cultural history, including displays on the Civilian Conservation Corps and early cave explorer Alvin McDonald. A film, Wind Cave: Two Worlds, provides an overview of the cave and prairie ecosystems.
