Northwest Passage Scenic Byway is Idaho’s longest byway, which at 202 miles, follows the route Lewis and Clark took through north-central Idaho. This beautiful route begins on US 12 at Lewiston, and traverses the winding Clearwater River Canyon. At Kooskia the byway splits with one segment heading south on Idaho Highway 13 toward the Camas Prairie and the town of Grangeville. Another segment continues east on US 12 along the Middle Fork of the Clearwater River, and the Lochsa Wild and Scenic River, through a magnificent wilderness culminating at the Lolo Pass Visitor Center.
