Out Yosemite National Park’s infamously strict permitting system

This 32.2-miler traverses one of the highest, harshest, and most achingly gorgeous strips of California’s High Sierra, from North Lake, outside Bishop, to Mosquito Flat, between Bishop and Mammoth Lakes. It links up swooping valleys surrounded by razor granite peaks that glow in rosy light each evening, drops into lake-studded alpine basins, and tops six passes between 11,150 and 13,040 feet. It’s Yosemite in everything but crowds. The entry fee? You need expert navigation skills for a mix of trails, abandoned footpaths, and cross-country travel, and you must be comfortable with traversing cliff bands, descending steep scree, and scrambling class 3 terrain over talus blocks that could crush a Suburban. From North Lake trailhead, link the following landmarks and trails: Lamarck Col, Darwin Canyon, Alpine Col, Goethe Lake, Piute Pass Trail, Desolation Lake, Puppet Pass, Elba Lake, Pine Creek Trail, Italy Pass Trail, Lake Italy, Cox Col, Dade Lake, Little Lakes Valley Trail, and Mosquito Flat trailhead. Local knowledge Payoffs for scrambling and routefinding? Edenic campsites. Here are the best: Darwin Canyon, Humphreys Basin, Granite Park, and between Lake Italy and Toe Lake.
