Mono Pass Trail


Starting from Mosquito Flat at the end of Rock Creek Road, (Little Lakes Trailhead) the Mono Pass trail climbs out of the Little Lakes Valley and goes to Ruby Lake, where sheer granite walls tower above the emerald waters. Crossing over Mono Pass the trail descends down Mono Creek with side trails to Pioneer Basin and the Recesses. The trail along Mono Creek eventually connects with the John Muir Trail near Quail Meadows and Lake Thomas A Edison. Do not confuse this trail with the other Mono Pass on the border of Yosemite National Park, reached by the Bloody Canyon trail. Use of Bear containers is required at Ruby Lake. Beyond Mono Pass, bear containers are the only practical way to store food due to the lack of tall trees.
