The Bitterroot National Forest encompasses 1.6 million acres in Montana and Idaho, almost half of which is made up of the Selway-Bitterroot Wilderness, the Frank Church-River of No Return Wilderness, and the Anaconda-Pintler Wilderness.
The Bitterroot offers winter sports from downhill skiing and snowboarding at Lost Trail Powder Mountain to cross country skiing, snowshoeing, and snowmobiling at Skalkaho Snowpark, plus almost endless backcountry opportunities. From spring through fall, the Selway, Snake, Salmon, and Middle Fork of the Salmon are nationally popular whitewater destinations. Hikers have 1,600 miles of trails to choose from in the forest's two defining mountain ranges: the Bitterroot, and the Sapphires.
The Bitterroot's four ranger districts (Stevensville, Darby, Sula, and West Fork) manage more than 35 campgrounds and picnic areas, and 8 rental cabins and fire lookouts.
