Hiking

One of the most direct routes of ascent starts at Sonora Pass, 2 mi south as the crow flies. Starting at the trailhead of the PCT on Sonora Pass, it is about a 2.5 mi hike with 1000 ft elevation gain to the top of a pass. From there, the easiest and most direct way is to turn northwest and follow the ridge that will lead to the summit. About halfway from the pass to the peak a small trail appears that heads directly to the peak. A second approach to the summit is from nearby Saint Mary's Pass trailhead. This trail approaches the peak from the other side of the mountain (the northwestern side) and is also a class 1 hike.
