This is the standard and best-known mountaineering route on Piz Kesch. It starts from the Kesch Hut and follows the south ridge, combining hiking terrain with short sections of easy scrambling. The route is generally straightforward in dry conditions but requires sure-footedness and alpine experience. Rock quality and route-finding can be variable, especially near the upper ridge. Snow or ice can significantly increase the difficulty and objective hazard. It is a classic non-glaciated alpine ascent rather than a technical climbing route.
