John Muir Trail is a 16.2-mile out-and-back foot trail in Yosemite National Park, California. It climbs 4,830 ft to a high point of 9,897 ft. Difficulty: very strenuous, from the NPS hiking-rating formula. That is the full hike: the mapped trail line runs 48 mi because it also covers connecting trails, so it is not the length of this hike. The figure is for the Park Service's “Half Dome via the John Muir Trail” hike, which uses this trail.
