Climbing the West Slope
From Winthrop, drive the West Chewuch Road and FR 51 to the Andrews Creek trailhead. Hike 12 miles to Andrews Pass, descend past the Spanish Camp guard station, and climb the trail toward Upper Cathedral Lake. Below the lake, follow the trail around the west ridge to a boot path, then climb scree and grass northeast into the western amphitheater and walk south to the highest, south summit, Class 2 with a short mantle. Early season brings snow and cornices on the north rim. A Northwest Forest Pass or day pass is required to park; fill out the free wilderness permit. Combine with Cathedral Peak.
