Along with the Muverans, the Wildhorn and the Wildstrubel, the Diablerets are one of the four distinct and glaciated massifs of the Bernese Alps that lie between the Rhone elbow and the Gemmi Pass. The main section of the mountain, between the cantons of Vaud and Valais, is part of the Rhone basin, through the rivers Grande Eau (north) and Lizerne (south). The easternmost part of the massif, that lies in the canton of Bern, is part of the Rhine basin, through the river Sarine (French, Saane in German). The Oldehore (Swiss German, Germanized: Oldenhorn) is the tripoint of the three cantons of Vaud, Valais and Bern, and several of the peaks have a German as well as a French name.
