Nez Perce National Historic Trail
The Nez Perce (Nee-Me-Poo) National Historic Trail follows the route taken by a large group of people of the Nez Perce tribe in 1877 to avoid being forced onto a reservation. The 1,170-mile (1,883 km) trail was created in 1986 as part of the National Trails System Act and is managed by the U.S. Forest Service.
