On my recent trip to follow the Nez Perce Trail, I rode the Hells Canyon Scenic Byway. The route from Oxbow Dam to Joseph, Oregon along National Forest Road 39 (USNF-39) was especially cool. Don’t miss the short turn off to go up to the Hells Canyon Overlook for a panoramic view over the canyon. If you ever find yourself in the area, take a day and ride / drive the whole thing. You will not be disappointed.
