Salmon River Scenic Byway

161.7 miles - Allow 3.5 hours

The Salmon River Scenic Byway begins near the Montana border at the 6,995-foot-high Lost Trail Pass. Lewis and Clark were forced to come this way in 1805 when their native guide lost the trail. The spectacular view from this vantage point has changed little since those travelers explored the West many years ago.

This route to Stanley follows the Salmon River through the Salmon and Challis National Forests. The river and its forks serve as important natural pathways into Idaho's rugged back country. The deer, elk and moose that often graze along the hills and meadows that line this road provide a glimpse of what is found in the wild country beyond.
