Used by the nimíipuu (Nez Perce) long before Euro-Americans came on the scene, the route over the Bitterroot Mountains, known today as the Lolo Trail, extends from Weippe Prairie to Lolo Pass along the Idaho-Montana border. Lewis & Clark followed this route on their trip across the mountains to the west coast in 1805. Looking for safety in Montana in late July of 1877, the non-treaty nimíipuu followed the same trail during the Flight of 1877.
Getting to Lolo Trail and Lolo Pass
U.S. Highway 12 (Lewis and Clark Highway)
Lolo Pass along U.S. Highway 12 begins in Greer, Idaho on the west end and ends 150 miles east at the Fort Fizzle interpretive site in Montana. This is a paved, two-lane highway with speed limits 50 miles-per-hour or less with few turnouts and limited opportunities to pass.
Lolo Motorway (Forest Road 500)
Lolo Pass along the Lolo Motorway is 119 miles long between Kamiah in the west and Powell in the east. It follows the traditional route of the Nez Perce more closely than Highway 12; however, this a single-lane, narrow, winding, primitive road that dips into saddles and ascends again onto ridgetops. The road is generally free from ice and snow by mid-July and usually accessible into October.
