The route begins on its eastern end at the town of Sisters in northern Deschutes County. It follows Oregon Route 126 westward over Santiam Pass south of Three Fingered Jack, then south along the valley of the McKenzie River. It then follows Oregon Route 242 eastward over McKenzie Pass, north of the Three Sisters then back to the town of Sisters. The route is considered a summer tour route, since the road over McKenzie Pass is closed in winter due to snowfall.
