General information
Grépon - A landmark in climbing history
The Grépon (3,482 m) is considered one of the founding climbs of modern alpinism in the Mont Blanc massif. Its first ascent in 1881 marked a turning point, with a direct rock line climbed at a level that was exceptional for its time.
Grépon - Mer de Glace traverse
Starting from the Envers des Aiguilles hut (2,523 m), the classic route to the Grépon follows a particularly aesthetic line on the east face. After crossing the bergschrund, often impressive depending on conditions, the route develops over nearly 800 metres of climbing. The ascent alternates sustained climbing sections and easier terrain (up to 5a), leading to the foot of the summit, which is reached via the famous Knubel crack (5c sustained), the key pitch of the route. The descent via the Nantillons glacier adds a serious alpine dimension, combining downclimbing, rappels and glacier travel.
Charmoz - Grépon traverse: a major alpine ridge
The Charmoz-Grépon traverse is a long and aesthetic ridge climb linking two major summits in a spectacular high-mountain setting. It includes the famous Mummery crack (5c sustained), one of the defining passages of the route. Highly dependent on the conditions of the Nantillons glacier, this traverse is aimed at experienced alpinists, capable of moving efficiently on both rock and glacier terrain.
