Aiguille du Midi, Chamonix-Mont-Blanc · France

Overview

The Vallée Blanche is one of the world's great ski descents — 24 kilometres of high-mountain off-piste from the Aiguille du Midi at 3,842m down to Chamonix at 1,035m, threading through crevassed glaciers, seracs, and open powder bowls that feel genuinely remote despite the cable car that drops you in. The descent begins with the notorious arête — a knife-edge ridge crossed in ski boots, crampons in hand, with a 1,000m drop on each side. Once down onto the glacier the terrain opens up. The classic route tracks through the Géant icefall and across the wide Mer de Glace, but variations into the Envers du Plan couloirs and the Pointe Helbronner add technical spice and solitude. A certified mountain guide is not optional — this is a glaciated, crevasse-riddled environment where conditions change daily and route-finding experience matters. Rent a guide through the Compagnie des Guides de Chamonix and book well ahead for prime January–March powder windows. Budget USD 300–500 per person for the guided day, cable car tickets, and lift passes. Spend a few days in Chamonix first to acclimatise and ski resort runs — arriving cold on the Vallée Blanche wastes the experience.
