Ski Season (January-March) — Chamonix and the Three Valleys are in full winter swing, with reliable snow on the high-altitude terrain.
Chamonix, at the foot of Mont Blanc, is one of the world's most famous ski and mountaineering towns, with the Aiguille du Midi cable car and the Vallee Blanche off-piste run as signature draws. Courchevel and the wider Three Valleys further south form the largest linked ski area in the world. In summer, the same peaks become a hiking and paragliding destination, with the Tour du Mont Blanc trekking route circling the massif over roughly two weeks.
Savoyard specialties like fondue, raclette, and tartiflette (potatoes, cheese, and bacon) are the regional staples, designed for refueling after a day on the mountain.
