Galena Summit on Highway 75 is an 8,701ft pass with 15 miles of 5-6% grade
The Sawtooth Scenic Byway (State Highway 75) crests Galena Summit at 8,701ft in Blaine County's Boulder Mountains — the gateway between Ketchum/Sun Valley and Stanley. The 15-mile climb runs a sustained 5-6% grade with tight switchbacks near the overlook. A loaded Class A or towing rig should plan a low-gear descent (engine braking, not riding the brakes) and expect chain/snow-tire controls outside summer; the pass holds snow into late spring.
