Best Time to Visit
Summer (June–August) is prime season, with warm days and cool Black Hills evenings. The Custer State Park Buffalo Roundup in late September is a world-famous event. Fall brings golden aspens to the Black Hills. Winter is cold but offers peaceful snow-dusted photography and snowmobiling. Spring (May) is pleasant but roads at higher elevations can still be closed from snow.
