Vallée Blanche glacier ski descent from Aiguille du Midi

Bucket List

The Vallée
Blanche

The most famous off-piste ski run in the world. Starting from the Aiguille du Midi at 3,842m, the Vallée Blanche descends 24km across glaciers, through seracs, and down the Mer de Glace to Chamonix — a vertical drop of 2,807m.

The classic route crosses the Argentière and Mer de Glace glaciers. Crampons are required for the narrow arête ridge at the start. A certified mountain guide is essential — crevasse risk is real and conditions change daily. Most groups ski it in 4–5 hours.
