Gros Rognon Map

Excellent off-piste skiing in an absolutely breathtaking setting. The environment is very serious and should not be underestimated; it is not maintained, secured or controlled, and the route follows extremely crevassed terrain. People die here every year and you should only set off if you have the necessary skills, experience and equipment for skiing on a glacier. The route is long and excellent weather is required to complete the route safely; this is no place for bad weather or poor visibility. If you have any doubt, hire a mountain guide. Make your way down the north ridge of the Aiguille du Midi, which is equipped with a handrail during the winter season but is still exposed! Crampons are not essential but make it more pleasant. Get your skis on at the broad col at the foot of the ridge. Follow the Vallée Blanche to the Col du Gros Rognon. Traverse high left maintaining your height round onto the E face. From here several options exist going either straight down next to the rocks (steeper with more crevasses), slightly further R or diagonally down and R. They all hold great cold snow and bring you back to the classic Vallee Blanche above the seracs.



Serious gradient of 30-38 degrees where a real risk of slipping exists.

Medium Exposure (E2)
