Lizzy Wenk's authoritative guide John Muir Trail

describes the 212-mile trail, running from Yosemite Valley to the summit of Mt. Whitney. It provides all 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. Note that the text includes the southbound trail description, while the full guide with the northbound description is available as a separate ebook product.
