Custer State Park Buffalo Roundup & Arts Festival

Feel the thunder at the 61st Annual Custer State Park Buffalo Roundup on Friday, September 25, 2026. Watch cowboys, cowgirls and park staff as they round up and drive the herd of approximately 1,300 buffalo. Be sure to plan for plenty of time at the three-day Arts Festival, September 24-26, where more than 100 vendors will offer fine arts and crafts and South Dakota made products. (On Friday, parking lots open at 6:15 a.m. Early arrival is recommended.) There is no admission to the Roundup or the Arts Festival, but a park entrance license is required September 24 and 26 (it is not required September 25).
