Bloody Canyon Trail


This route was used to cross the Sierras before wagon roads were built and is named for the injuries to stock that made this rugged crossing. This trail is still not recommended for stock. The trail climbs over a ridge to view Walker Lake and goes up Bloody Canyon past Lower and Upper Sardine Lakes. At the head of the canyon the trail crosses Mono Pass into Yosemite National Park, and continues toward the Kuna Crest or Parker Pass Creek areas of the park. Do not confuse this with the Mono Pass that goes to Pioneer Basin and the Recesses in the Rock Creek and Little Lakes Valley area. Yosemite wilderness regulations do not allow camping in Parker Canyon.
