Battlefield Road is a nearly five-mile self-guided vehicle tour that takes visitors to where the Battle of Little Bighorn’s first shots were fired June 25, 1876, and where most of the U.S. Seventh Cavalry regiment was surrounded and besieged through the night. Approximately 7,000 Sioux, Cheyenne and Arapahos were camped in the Little Bighorn River valley, near present-day Garryowen, Mont., when cavalry led by Lt. Col. George Custer attacked.
