Climbing the West Face
From Lake Louise, drive west on Highway 1 to the Lake O'Hara parking lot and ride the bus 11 km to Lake O'Hara, or walk the road before dawn. Hike past Lake Oesa and up the loose Abbot Pass alpine route to the pass. The West Face is a sustained snow and ice climb of 40 to 45 degrees for about 400 m, with short 50-degree sections and a corniced summit ridge. Rockfall from the face and the pass slopes is constant once snow melts, so start very early while the face is frozen. Bring crampons, an axe and second tool, a helmet and rope. A Lake O'Hara bus reservation and a Parks Canada pass are required.
