Chamonix has free shuttle buses between all the areas and an excellent railway service. Night buses are a good way to get back from a night out in Chamonix, though it is also very pleasant to walk back to the chalet. At night we recommend you only walk along the very quiet and well-lit road beside the railway (full directions and maps will be sent on booking). Taxis are widely available but are not cheap.
Free shuttle buses run regularly through Les Praz — catch them either at the stop near the chalet or at the Flegere lift — to Chamonix, Le Tour, Les Grands Montets, Les Houches and various other destinations. Much improved in the last few years, they now run every 10 minutes at busy times. More info on routes here
In winter, there is also a daily bus to Courmayeur, returning in the evening. It’s free for Mont Blanc Unlimited pass holders of 2 days or more. Reservations must be made by 5:00p.m. the day before on +33 (0)450 530 115, or in person at their office by the railway station.
The train is much the most pleasant way to get around the valley. It’s free with your ski pass between Servoz and Vallorcine, and stops in Les Praz. It’s very punctual but there can be long gaps between trains so check the timetable before you set out, and take one with you if you plan to return on it. Even if you have a car, it’s often preferable as it allows for flexibility. Excellent for Les Grands Montets and Vallorcine — not recommended at all for Les Houches or Le Tour — take the bus, or access Le Tour from Vallorcine.
Taxis are expensive in Chamonix but are quite readily available and handy when the weather is very cold. They can be called from any bar or restaurant, but it’s best to book in advance at busy times. There’s a list of numbers at the chalet.
