Trout locations and species found along the John Muir Trail. Use the Far Out app with its John Muir Trial map for mileage locations. ($24.99) Mileages listed are for the JMT southbound, from Happy Isles in Yosemite Valley to Whitney Portal. I used PCT northbound mileages (also in Far Out) for the two commonly-used trails between Horseshoe Meadows and the JMT (Cottonwood Pass Trail and Cottonwood Lakes Trail).
