Buffalo Roundup and Arts Festival in Custer
The Buffalo Roundup and Arts Festival draws thousands to Custer State Park each late September to watch cowboys and cowgirls drive the park's roughly 1,400-bison herd across five miles of prairie into corrals, a working ranch management event turned public spectacle that has run since 1965.
Custer State Park's bison herd began with just 36 animals purchased in 1914, one of the earliest organized efforts anywhere to preserve a species that had been hunted to near-extinction across the American West within living memory of the park's founders.
