The second most remarkable summit of the Pilat behind the Crêt de la Perdrix, this giant of gneiss and granite reveals, from its height of 1,364 meters, its trump card: a bird's-eye view of the Pic des Trois dents and the valley of the Rhône which extends at its feet. On a clear day, the gaze wanders to strange apparitions which imprint their reliefs on the horizon line: the Vercors mountains, the Ecrins and the Mont-Blanc range, for a natural spectacle that is both unreal and majestic.
