Northwest ridge from the Scerscen side
This is a documented alpine ridge route on Piz Zupò from the Scerscen side. It is more committing and generally more technical than the normal route, with sustained mixed climbing on the ridge. Glacier travel is part of the approach, so crevasse and serac hazards may be present depending on conditions. The ridge itself can involve exposed sections and difficult route-finding. It is suitable only for experienced alpinists with solid movement on mixed terrain. Exact timings and metrics are not consistently documented in the sources I can verify.
