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.

The elevation profile shows trail distance vs elevation and plots your current location on the trail. Each waypoint is plotted on the profile. Each waypoints is clickable, opening to the waypoint's detail page.

The guidebook lists every waypoint in order by distance along the trail.

Each waypoint includes a detail page, providing further details about that particular waypoint. Details include the waypoint's mileage point and elevation, photographs of the waypoint, distance northbound and southbound to the next water source, a Trail Register where you may post comments and read other users' comments, and other details that will help you during your hike, and help you plan your hike.

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.

    Trail map for use on your cell phone. Using a solar charging system, I kept my phone charged so I could use this guide. It is very accurate. The only time we had a problem was when the guide said there was water at mile 200 near the camp site. We had to go an additional 4 miles to find a good water source near a camp site which was at Crabtree Meadows. Or go back about 2 miles to a large cre

    Was quite useful on my recent JMT hike. One major bug was irritating: There was no way to switch between topo and satellite maps, and sometimes on the same scene one panel would be topo and one adjacent panel satellite. Irritating. Would like to be able to add campsites, bear sitings and comments without logging in, to be uploaded when I got back home. I would like to be able to view selected
