The Southwest Ridge is a named alpine ridge route on Mont Pelvoux. It is a long, exposed climb combining rock, snow, and mixed ground. The route is more technical and committing than the standard glacier-couloir ascent. Route-finding can be complex, especially where the ridge breaks into towers and ledges. Protection may be sparse in places, and the route demands solid alpine experience. It is a classic objective for climbers seeking a more aesthetic and sustained line on the mountain.
