Custer State Park is a state park and wildlife reserve in the Black Hills of southwestern South Dakota, USA. The park is South Dakota's largest and first state park, named after Lt. Colonel George Armstrong Custer. The area originally started out as sixteen sections, but was later changed into one block of land because of the challenges of the terrain.
The park is home to a famous herd of 1500 free roaming bison. Elk, mule deer, white tailed deer, mountain goats, bighorn sheep, pronghorn, mountain lions, and feral burros also inhabit the park. The park is famous for its scenery, its scenic drives (Needles Highway and the wildlife loop), with views of the bison herd and prairie dog towns. This park is easily accessible by road from Rapid City. Other nearby attractions are Wind Cave National Park, Mount Rushmore, Jewel Cave National Monument, Crazy Horse Memorial, and Badlands National Park.
