Begin at Mono Pass trailhead, on the Tioga Road six miles east of Tuolumne Meadows

This historic trans-sierra route has been used for hundreds--maybe even thousands--of years. The trail climbs gently at first from the trailhead through wet meadows and rushing creeks. At the Spillway Lake junction, the trail climbs steadily and more steeply to Mono Pass. Don't miss the spectacular view of Mono Lake and Bloody Canyon (from the pass, hike an additional 0.75 miles to Upper Sardine Lake).
