It bills itself as the "World's Largest Outdoor Rodeo and Western Celebration." The event, claimed to be one of the largest of its kind in the world, draws nearly 200,000 annually.
Lodging fills up quickly during the peak tourist season throughout southern and eastern Wyoming, into northern Colorado and western Nebraska. The celebration is held during the ten days centered about the last full week of July. In 2008, Cheyenne Frontier Days was inducted into the ProRodeo Hall of Fame.
Cheyenne Frontier Days only has a full-time staff of five people year round. The rest of the work of running the myriad of events is done by volunteers, more than 2,500 of them every year. There is preparation before the event and cleanup after the event as well as all of the work that needs performed during the actual event.
