Sawtooth Scenic Byway
75Stanley to Ketchum
Idaho State Highway 75 over 8701 ft Galena Summit, with the jagged Sawtooth peaks filling the valley below.
State Highway 75 carries the Sawtooth Scenic Byway between the resort town of Ketchum and Stanley, climbing over Galena Summit at 8701 ft, said to be the highest highway summit in the region. The drop from the summit into the Sawtooth Valley reveals one of the most striking ranges in the United States, with more than fifty peaks over 10,000 ft rising to the west and the headwaters of the Salmon River threading the meadows below. It runs through the Sawtooth National Recreation Area, with alpine lakes, river access and abundant wildlife along the way. Mind the up-to-six-percent grades and switchbacks on Galena, winter snow and ice at altitude, and wildlife on the road at dawn and dusk.
