Mono Pass Trail

Starting from Mosquito Flat at the end of Rock Creek Road, 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.

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.

Common Destinations: Ruby Lake, Mono Pass, Pioneer Basin, Hopkins Creek.
Note: This is not Mono Pass near Yosemite’s Mt Dana, use Bloody Canyon Trail for that area.
