The Lewis and Clark 
National Historic Trail

Between May 1804 and September 1806, Lewis and Clark’s Corps of Discovery traveled 3,700 miles from the plains of the Midwest to the shores of the Pacific Ocean - and back.  In their search for a water route to the Pacific, they opened a window on the West for the young United States.

The Lewis and Clark National Historic Trail was established by Congress in 1978.  Idaho’s Lemhi Valley, Camas and Weippe Prairies, and Salmon and Clearwater Rivers played an important role for the Lewis and Clark Expedition. The trail through the Lemhi Valley continued to be used for exploration and fur trade through the 19th century.  Portions also facilitated regional and local settlement, mining and transportation.
