Buses link Chamonix directly with Geneva Airport, but it is not recommended.
I do not recommend this as a way to get to us, but they can be useful if one person is arriving a day later and could be collected from the bus station.
All these companies stop only at the central bus station which is 2.5 km from the chalet. If you arrive before 7.30pm you can get a bus from there to Les Praz. It’s then a 5-10 minute walk from the Flegere stop to the chalet, or you may be able to get a bus that stops at Les Vardesses which is closer. It’s a lot to figure out when you arrive, and a real problem in case of delays and bad weather.
Taxis are very expensive in Chamonix. Currently a taxi will charge thirty (yes!) euros to take you from Chamonix to Les Praz. Bus and taxi will always be more expensive than a transfer, and very inconvenient. A transfer service will take you directly to the door of the chalet.
There are three companies operating on the route:
Swisstours (via Geneva)
Allow plenty of time to get to the airport as traffic can cause delays if they go through Geneva city centre. They are extremely reliable, however, and can be very useful at off-peak times when the transfers don’t run so often.
Easybus and Ouibus (Airport only)
Easybus runs early and late, and for a very low price. As with many offerings from this company, reviews have been mixed!
Ouibus / BlaBlaBla is a low cost French service which I have heard is rather better. The site is available in English.
Flixbus also operate on this route
Just to recap – the buses are good possibilities if one person needs to arrive later and can be collected by car from the bus station in Chamonix Sud, but are really not suitable in general due to the truly ludicrous taxi prices.
