The Lewiston Roundup is a proud member of the Professional Rodeo Cowboys Association (PRCA) and the Big 4 Rodeo Association. As part of the Columbia River Circuit, the Lewiston Roundup has brought high-quality and unsurpassed energy in rodeo entertainment to North-Central Idaho for 86 years. It's more than just riding and roping; the Lewiston Roundup is host for a variety of other events all year long. In keeping with the generous spirit of the cowboy way, the Roundup donates a large portion of event proceeds to charitable organizations throughout the year.
