The John Muir Wilderness is characterized by deep canyons, meadows and many streams and lakes. The John Muir Wilderness contains hundreds of miles of trails. Three of the more well known are the Pacific Crest, John Muir and Mt. Whitney trails. The 10.7 mile Mt. Whitney Trail begins at Whitney Portal, near Lone Pine, and leads to the highest peak in the Lower 48 states. Wheelchairs may be used in wilderness, but all other mechanical travel, including bicycles, is prohibited.
Winter offers an entirely different experience.
Skis and snowshoes become the mode of transportation. Pets are not permitted in National Park wilderness and are under some restriction in National Forest wilderness. Maximum group size is 15 people and 25 head of stock. Permits are available at the Forest or Park Service Ranger Station closest to the trailhead entry location. During heavy use periods many popular trails are subject to a quota, where a set number of people may enter the wilderness each day.
