"the abode of devils")[3] are a huge ice-covered mountain massif of the Alps, culminating at the Sommet des Diablerets (VS) at 3,216 metres (10,551 ft) above sea level and almost straddling the border between the Swiss cantons of Vaud (VD) and Valais (VS).

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).

Also notable is the tower-like peak of the Quille du Diable ("devil's skittle," also known as Tour St-Martin; VS, 2,908 m (9,541 ft)) that overlooks Derborence from the edge of the Tsanfleuron plateau.

Along with the Culan, the Tête Ronde, and the Scex Rouge, the main summit forms an amphitheatre of limestone cliffs with numerous water falls, surrounding the valley of Creux de Champ and overlooking the village of Les Diablerets from a height of over 2,000 metres.

The main summit, although not very distant from the Scex Rouge station, can not be easily reached as it involves the crossing of the much-crevassed Diablerets Glacier, though it is accessible to more intrepid hikers.
