Lizzy Wenk's authoritative guide describes the 212-mile John Muir Trail, running from Yosemite Valley to the summit of Mt. Whitney. It provides all the necessary planning information, including up-to-date details on wilderness and permit regulations, food resupplies, trailhead amenities, and travel from nearby cities. Useful essentials are updated GPS coordinates and maps for prominent campsites (along with an updated list of sites along the trail), trail junctions, bear boxes, and other points of interest. The trail descriptions also include natural and human history to provide a workout for both body and mind — a must-have for any Muir Trail enthusiast.
