Due to its isolated position on the southern border of the Mercantour National Park, Cime du Diable, which rises to an altitude of 2685m, can easily be seen, despite its altitude, from the Mediterranean, with only 40km lying between it and the Côte d’Azur. It watches over the Cirque des Merveilles. Its evocative name recalls the way that high mountains were viewed in the past as being in some way cursed. Le Pas du Diable, located on the slopes of the cime of the same name, provides the link, thanks to GR52, between Vallée des Merveilles and the site of L'Authion.
