Grand Bec, Mountain summit in Savoie, France.

Grand Bec is a 3,398-metre summit in the Massif de la Vanoise, in Savoie, France, above the communes of Champagny-en-Vanoise and Planay. Its upper part is a dark grey, almost black rock mass of layered, jagged facets and loose scree, topped by a sharp peak. A broad glacier of snow and ice clings to the upper left flank and spills downward, while a smaller snowfield sits on the upper right face and thin tongues of snow lodge in the gullies below.

Grand Bec, 3,398 metres high, lies in the Massif de la Vanoise in Savoie. The summit is shared by the communes of Champagny-en-Vanoise and Planay. Its dark layered rock and the glacier on its upper left flank are the features that identify it in views from the surrounding valleys.

Grand Bec lies in the Vanoise massif above the communes of Champagny-en-Vanoise and Planay, and its name is shared with a summit in Switzerland's Mont-Blanc massif, so French maps distinguish the two by massif. The 3,398-metre summit is climbed from the Vanoise side, and the dark layered rock and glacier of its upper left flank are what walkers in the valleys below recognise.

The main approach for climbers is via a nearby mountain refuge that serves as a natural starting point for the ascent. Pay attention to weather conditions and bring proper gear, as the route is exposed and demands technical skill.

Grand Bec reaches 3,398 metres in the Massif de la Vanoise, on the territory of Champagny-en-Vanoise and Planay in Savoie. The name is shared with another Grand Bec in the Mont-Blanc massif in Switzerland, so check which summit a route description refers to.
