Lewiston to Montana and Kooskia to Grangeville
This beautiful byway is the easiest way to trace the Lewis and Clark Expedition route along the Clearwater and Lochsa rivers. The Lewis and Clark National Historic Trail lies on the mountainous ridges above the rivers in this land of the Nez Perce Indians. This byway follows the water route Lewis and Clark sought but were unable to navigate.
From the west this beautiful route begins at the Washington state line on Hwy 12 and traverses the winding Clearwater River Canyon, passing through the Nez Perce National
Historical Park areas of Spalding and Kamiah and the towns of Lenore, Orofino, Kamiah, and Kooskia. At Kooskia, the byway splits, with one route continuing on Hwy 13 south to
the Camas Prairie and the town of Grangeville, while another heads east on Hwy 12 along the Middle Fork of the Clearwater River and the Lochsa Wild and Scenic River, toward the Montana border.
A free cassette/CD audio tour of this byway is available at regional visitor centers. Get more information at northcentralidaho.info. Lewiston to Montana: 176 miles, 4 hours. Kooskia to Grangeville: 26 miles, 40 minutes.
