The South Ridge is the classic mountaineering line on Gspaltenhorn and is documented in standard alpine sources. It is a mixed alpine route with sustained scrambling and climbing on exposed ridge terrain. Conditions can vary significantly with snow and ice, especially early in the season. The route is generally considered a serious but non-technical alpine ascent in stable weather. Objective hazards include loose rock, cornices, and route-finding issues on the ridge. Because documented figures vary by source and I am not confident enough to state them precisely, no time or distance values are given.
