Venture just a couple miles to visit the Ice Age at the Mammoth Site archaeological dig site, or go just a couple miles in the other direction to Wind Cave National Park (11 miles) where American Bison roam free at Wind.  Swim and boat at Angostura Lake State Park (13 miles) or plan a day trip and visit Crazy Horse National Monument (37 miles), Badlands National Park, Custer State Park (20 miles) and Sylvan Lake (38 miles), Devils Tower (152 miles), Mount Rushmore (51 miles), and much, much more.
