North of Ketchum and Sun Valley, Hwy-75 climbs through rising tracts of forests and mountains to top out after twenty miles at the spectacular panorama of Galena Summit (8701ft). Spreading out far below, the meadows of the Sawtooth Valley stretch northward. The winding road – dubbed the Sawtooth Scenic Byway – meanders beside the young Salmon River, whose headwaters rise in the forbidding icy peaks to the south, as the serrated ridge of the Sawtooth Mountains forms an impenetrable barrier along the western horizon. The main highlight along this stretch is Red Fish Lake (just off the highway, 60 miles north of Ketchum), beautifully framed by Mount Heyburn and Grand Mogul peaks, home to sockeye salmon and plenty of hiking and camping opportunities.
