Chamonix and Courmayeur: separate ski areas
The French side includes Brévent–Flégère, Grands Montets, Balme–Vallorcine and Les Houches–Saint-Gervais. Across Mont Blanc, the Courmayeur piste area is in Italy. Search Bochard Bas on the French side or Val Veny in Courmayeur; map gaps do not indicate skiable connections.
The sector markers are for orientation only. Courmayeur is not reachable from Chamonix on marked pistes; check travel and access separately. Small French beginner areas such as Les Planards and La Vormaine are outside this five-area extract.
The map also shows 20 selected named OSM backcountry fragments, including Vallée Blanche variants, Envers du Plan and Pas du Chevre. They are separate reference traces, not a complete or recommended itinerary.
Check the limits before heading out
This line-only snapshot omits some polygon pistes and may have incomplete or outdated names and connections. It is not a live opening report or a navigation map, and no direction arrows have been verified. Check the official Chamonix and Courmayeur maps and current openings linked above.
The purple dashed Vallée Blanche and other off-piste lines are historical OSM traces, not marked pistes or safe routes. This glaciated terrain has crevasses, avalanche hazards and changing access; the arête and return are not a verified connected path on this map. Do not use these lines for navigation. Check current conditions and seek a qualified local mountain guide. Skyway Monte Bianco and Panoramic Mont-Blanc cable lines remain excluded and no marked-piste connection to Courmayeur is implied.
Treat Chamonix as several areas
Les Houches, Brévent–Flégère, Grands Montets and Le Tour–Vallorcine are distinct destinations in the valley. Seeing them on one overview does not establish a continuous piste route between them. Choose a specific sector before planning.
Separate ski legs from transport and glacier terrain
For a journey between sectors, review any walking or transport legs and their data availability. Do not treat the mapped Vallée Blanche traces as marked piste connections. Aiguille du Midi sightseeing access and glacier itineraries require separate official information and appropriate local expertise.
