The South Ridge is a documented alpine route on Zinalrothorn and is more demanding than the normal route. It is a long, exposed ridge climb with sustained mixed ground and route-finding. Conditions can vary significantly, especially on the snow and ice sections near the ridge crest. The route is suitable for strong climbers comfortable with exposed alpine terrain and efficient ropework. It is less commonly used than the normal north-ridge ascent. Descent is typically made by a standard route rather than reversing the full ridge in poor conditions.
