About Harding County Fair

The Harding County Fair in Buffalo celebrates South Dakota most remote and northwestern county — a short-grass prairie county bordering Montana and North Dakota where cattle ranching on vast native grass ranches sustains one of the most sparsely populated communities in the Great Plains.

What to Expect

Expect a small fair with livestock exhibits, 4-H competitions, rodeo events, and the authentic frontier spirit of one of the Great Plains most remote ranching counties.

Visitor Tips

Buffalo is a tiny county seat in the short-grass prairie of northwest South Dakota. The Cave Hills and Slim Buttes formations provide dramatic geological features in an otherwise flat landscape. The county borders both Montana and North Dakota.
