Guthook's JMT Guide

Guthook's John Muir Trail Guide is a smartphone guide for your hike on the John Muir Trail. NO INTERNET OR CELL PHONE COVERAGE is needed after the initial app setup. Following on the success of the popular Guthook's Guide series for the Pacific Crest Trail, John Muir Trail Hiker covers the 210.5 mile John Muir Trail from Happy Isles in Yosemite National Park to the summit of Mt. Whitney. It also includes the entire Mt. Whitney Trail (10.4 mile trail from Whitney Portal to Mt. Whitney summit) and many side trails. The various JMT exit or 'bail-out' side trails are mapped as well.

John Muir Trail Hiker use a combination of your phone's GPS, downloaded topo maps, and the Google Maps interface to accurately locate your position on the trail. No phone service? Not a problem -- your phone's GPS pinpoints your location on top of topo maps downloaded as part of the app.

A bright red line indicates the location of the main trail on the map. Side trails are indicated in blue. Waypoints of interest to the hiker are plotted on the map. There are also markers on the map every mile or kilometer of the trail track.

About the John Muir Trail: The John Muir Trail, or JMT, is revered as one of the most pristine and beautiful trails in the world. The 210.5 mile trail makes its way through the heart of the Sierra Nevada Range in Central California. Much of the trail is above 10,000 feet elevation and is quite steep, making this a rather difficult trail. Most hikers hike the JMT southbound, beginning at Happy Isles in Yosemite National Park, and ending at the summit of the highest peak in the "lower 48" -- Mt. Whitney. It takes about 2-3 weeks to hike the entire trail (some hikers are faster, some are slower). Many hikers complete the entire trail in one go, and countless others enjoy hiking a few miles along the trail via the many remote side trails that branch off the JMT.
