The Hardin area is rich in history. Each year the Crow celebrate their heritage at the Crow Fair with a powwow which is the largest in the state.
13 miles south of Hardin is the Little Bighorn Battlefield, where the Northern Plains Indians defeated Custer and the U.S. Army.
The world famous Custer's Last Stand re-enactment in June is one of Custer Country's biggest annual attractions, an annual event celebrated in Hardin. Sioux, Northern Cheyenne, and Arapaho warriors under the leadership of Sitting Bull, Crazy Horse, and Gall fight George Armstrong Custer's Seventh Cavalry troopers. The re-enactment script is based on Crow Tribal Elder Joseph Medicine Crow's translation of oral and written Native American narrative beginning before Lewis and Clark's epic journey almost 200 years ago.
