Climbing the Southwest Slopes
In Yosemite, park at the Mono Pass trailhead in Dana Meadows on Tioga Road (CA 120), a few miles west of Tioga Pass; the lot fills early on summer weekends. Follow the Mono Pass Trail across the Dana Fork and through forest, then leave it and climb open southwest slopes of sand, grass and talus to the broad, flat summit. The route is Class 1 the whole way and navigation is easy in clear weather. The upper slopes are exposed to wind and lightning, so start early and descend if storms form. Mono Lake views from the top are excellent.
