The John Muir Trail (JMT) is one of the world's most spectacular treks and is North America's best known mid-distance walking trail. It runs for 216 miles through the high Sierra Nevada mountains of California, from Yosemite Valley (El Capitan and Half-Dome) to the summit of Mount Whitney (14,496ft), the highest peak in the US outside Alaska. The route is described in twenty-one-day stages. All you need to know to plan and prepare for your trip is contained within this guide, from obtaining trekking permits to buying trek food and forwarding food caches along the trail. Abundant advice is given on such topics as dealing with inquisitive bears, coping with altitude, negotiating river crossings, as well as tips on booking transport to and from the trailheads and on what equipment to take. In addition, there is a detailed description of the flora and fauna of this remarkable region. The walking trail, which is named after the great 19th-century Scottish naturalist, and writer John Muir, is entirely through the wilderness of the American West. It runs through three National Parks: Yosemite, Kings Canyon and Sequoia National Parks.
