North Face via the Grands Couloirs
This is the classic and best-known mountaineering line on Pointe de la Grande Casse. It is a serious alpine snow-and-ice route on the north face, with objective hazards from rockfall and avalanche conditions depending on season and temperature. The route is typically climbed in stable early-morning conditions when the couloirs are firm. Upper sections can require mixed climbing and careful route-finding to reach the summit ridge. It is not a hiking route and demands full alpine equipment and experience. Conditions can change quickly, and the face is often considered a committing objective.
