Yakima to Salmon Road Trip Guide: Scenic Drive Through Washington and Idaho

This 325-mile route from Yakima, WA to Salmon, ID traverses the dramatic transition from the arid Columbia Basin to the rugged Salmon River Mountains. The drive typically takes 5.5 to 7 hours without stops, but the real value lies in the detours.

US-12 east from Yakima follows the historic Nez Perce Trail, where in 1877 Chief Joseph led his people across the Bitterroots. Today, the road offers access to the Palouse region's rolling wheat fields and the dramatic Clearwater River Canyon.

Key highways include US-12 east to Lewiston, then US-95 south through the Nez Perce Reservation, and finally ID-28 along the Salmon River. The route is mostly two-lane highway with limited services between towns.
