Chamonix mobile app
The Compagnie du Mont-Blanc, Chamonix Tourist Office and La Chamoniarde mountain safety and rescue organisation all provide practical information via the free, official Chamonix-Mont-Blanc valley mobile app!
In winter: ski runs, map of the slopes, webcams, weather forecast, etc.
In summer: Lifts, hiking ideas, mountain bike trails, webcams, town map and directory, transport, mountain conditions, route reports, mountain shelter information, and more. You can even top up your pass without calling in at the ticket office!
Continued use of GPS in the background can decrease battery level.
