Sawtooth National Forest, part of the larger Northern Rockies ecosystem, covers approximately 4,430 square kilometers across central Idaho. The landscape is characterized by high granite peaks, including the iconic Sawtooth Range with elevations surpassing 3,600 meters; crystal alpine lakes, such as Redfish Lake and Alturas Lake; and floodplain valleys carved by snowmelt and tributary rivers. The forest surrounds popular resort towns like Sun Valley and Ketchum, which provide access to trailheads, lodging, and cultural amenities. Beyond the ski season, the area is a hub for hiking, backcountry camping, rafting on the Salmon River, and winter cross-country skiing. Within the protected Sawtooth Wilderness, restricts on mechanized access preserve primitive travel along ridgelines and deep glacial valleys. The forest’s multi-use designation supports a mix of timber harvesting, grazing, recreation, and conservation, with extensive trail networks connecting permits and trailheads across a patchwork of public and private lands.
