Begin at Mono Pass trailhead along Tioga Pass Road, six miles east of Tuolumne Meadows. The trails climbs gently at first from the trailhead through we 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.
It is about 4 miles one way, 8 miles there and back. Takes roughly 4-6 hours.
You can extend this hike by hiking a half mile from the pass to Upper Sardine Lake.
