The first cave to be designated a national park, Wind Cave features the world’s largest concentration of rare boxwork formations below ground and a 33,970-acre wildlife sanctuary on the surface. The cave is one of the longest and most complex caves in the world. Located in the southern Black Hills near Hot Springs, the park is home to bison, elk, and other wildlife that roam the rolling prairie grasslands and forested hillsides. Activities include hiking, bird watching, wildlife viewing, backcountry camping, Junior Ranger programs, and cave tours.
