Climbing the South Slope via Lake Italy
From US 395 northwest of Bishop, drive Pine Creek Road past Rovana to the Pine Creek trailhead. Hike the Pine Creek Pass and Italy Pass trails through Granite Park, cross Italy Pass, and drop past Jumble Lake to camp at Lake Italy. From the north shore, skirt small cliff bands to a broad sandy slope, then follow the Class 2 southwest ridge over big boulders to the top of the Mono Divide. Direct lines on the south side reach Class 3. Hilgard pairs well on the same day. Expect a long exit back over the pass. An Inyo National Forest wilderness permit is required overnight.
