The East Ridge is a documented alpine route on Lyskamm Orientale and is generally treated as a serious ridge climb. It involves sustained snow and ice travel with exposed ridge sections and potential cornice problems. The approach is glaciated and requires competence in crevasse rescue and navigation. Conditions on the ridge can change quickly with wind and fresh snow. It is less a rock climb than a high, committing snow ridge ascent. The route is suitable only for experienced alpinists in stable weather.
