West Couloir and West Ridge (Normal Route)
This is the standard and best-known route on Ober Gabelhorn. It ascends the west side via the West Couloir to the West Ridge, then follows the ridge to the summit. The route is a classic alpine mixed climb with snow, ice, and rock, and is usually less severe than the north-east ridge. It still requires good conditions because the couloir can be exposed to rockfall and the ridge can be corniced. The route is long and committing, with route-finding that can become complex in poor visibility. It is the normal ascent line described in major alpine guidebooks.
