The Rosablanche is a mountain of the Swiss Pennine Alps , overlooking the Lac des Dix in the canton of Valais . It lies on the range between the valleys of Bagnes (west) and Hérémence (east), north of Le Pleureur .

The normal routes from the north side are from Barage de la Grande Dixence (Dix lake) in Val d’ Heremence, and from Siviez in Val de Nendaz, with the car access in both cases. From the Siviez side there is bus service as well. These are non-technical but very attractive glacier routes. There are also more technical portions.
