The South Ridge is a documented alpine ridge route on the peak and is generally less snow-committing than the north-face lines. It is a mixed rock-and-snow climb with sustained exposed sections and route-finding on the crest. The difficulty is mainly in the steepness, exposure, and the quality of the rock rather than in long technical pitches. In early season it may hold snow and ice, increasing the seriousness of the ascent. It is a true mountaineering route and requires competence on exposed alpine terrain. Conditions on the ridge can vary significantly with snow cover and freeze-thaw cycles.
