Discover the Sawtooth National Forest, more than two million acres of rugged mountains, alpine lakes, dense forests, and sweeping valleys in the center of Idaho. Named after the jagged peaks that dominate the forest, the forest hosts a wide variety of recreation, from very primitive settings like the Sawtooth Wilderness to highly developed recreation sites such as Redfish Lake Recreation Complex.

In addition to the Sawtooth Wilderness, the forest contains parts of the Cecil D. Andrus-White Clouds Wilderness, set along the Salmon River, and the Hemingway-Boulders Wilderness, known for its geological formations. All three wildernesses are home to an impressive number of granite peaks over 10,000 feet.

More than 700 miles of trails provide opportunities for hiking, biking, and horseback riding, while some 500 miles of motorized trails offer exciting off-highway vehicle adventures. The forest hosts over 3,500 miles of perennial streams, 7,600 acres of lakes, and many game-management units, making for excellent fishing, hunting, and water activities.

In the winter, head to one of four premier ski resorts—Sun Valley Resort, Soldier Mountain, Pomerelle Mountain Resort, and Magic Mountain Ski Resort—or embark on the forest’s many cross-country ski and snowmobile trails.
