The north-west ridge is a documented alpine route on Grosses Grünhorn. It is a more serious mountain route than the normal south-west approach and is less commonly climbed. The line involves glacier access followed by ridge climbing on snow and mixed ground. Objective hazards include crevasses on the approach and possible unstable snow or ice on the ridge. Because documented public details are limited in the sources available here, the exact grade and timings are left unspecified.
