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, conservationist and writer John Muir, is entirely through the unspoilt wilderness of the American West and passes through three national parks: Yosemite, Kings Canyon and Sequoia National Parks.
