Richland County Fairgrounds

The Richland County Fairgrounds Rodeo Arena in Sidney, Montana, is home to one of the MonDak region’s most enduring and celebrated traditions. First established as an official county fair in 1920, the fairgrounds have grown from a small community street fair into an event that now welcomes more than 30,000 visitors each year. The rodeo arena stands at the center of this legacy, showcasing top‑tier competition, local ranching heritage, and the community spirit that has defined Richland County for more than a century.
