Cime du Diable, Mountain summit in Alpes-Maritimes, France

Cime du Diable rises to 2685 meters (8810 feet) and sits in the southern part of Mercantour National Park, roughly 40 kilometers from the Mediterranean coast. The mountain features steep ridges and is connected to several neighboring peaks that define this alpine zone.

The summit lies on the southern edge of Mercantour National Park, above the Roya valley, and closes the mountain chain that begins at Mont Clapier and separates the Gordolasque valley from the Vallée des Merveilles. Its name belongs to a cluster of diabolical toponyms around the peak, alongside the lacs de l'Enfer, the pas du Trem and Valmasque, the "valley of the witch". The origin is uncertain: a deformation of roots meaning "rocks" or "mounts", the frequent thunderstorms on the summit, or the clergy's view of the rock engravings of the Vallée des Merveilles as malign.

The name Cime du Diable, Devil's Peak, belongs to a cluster of diabolical toponyms around the summit: the lacs de l'Enfer (Hell Lakes), the pas du Trem (from "tremblement", trembling) and Valmasque, "valley of the witch". Its origin is uncertain: a deformation of roots meaning "rocks" or "mounts", the frequent thunderstorms on the peak, or the clergy's view of the Vallée des Merveilles engravings as malign.

The route starts from Tueis refuge parking area and follows marked trails through Punta dei Tre Comuni and several mountain passes on the way to the summit. The climb is demanding and requires sturdy footwear and experience with alpine conditions.

From the summit, you can see both Monte Bego and Monte del Grand Capelet, with views reaching across the Franco-Italian border territories. This panorama reveals the mountain's position as a natural dividing line between the two countries.
