General information
The Weissmies Traverse, an Iconic 4000m Peak in the Swiss Valais
The Weissmies (4,023m), located in the Saas Fee valley, is one of the more accessible 4000m peaks in the Swiss Valais for mountaineers with some previous cramponing experience. The traverse from the Almageller Hütte offers a particularly varied route, ascending the southeast ridge before descending over the glacier towards Hohsaas. The variety of terrain makes this an ideal climb for discovering the high peaks of the Valais, with outstanding views across the Swiss Alps.
A Varied Ascent Combining Ridge and Glacier
The Weissmies traverse combines snowfields, a rocky ridge and glaciated terrain. The ascent does not require specific rock climbing experience, but you need good physical fitness, confidence at altitude and some previous experience using crampons. This trip is designed for occasional mountaineers looking to continue their progression on 4000m peaks in a varied high-mountain environment.
