Eurostar runs ski trains to Moûtiers half an hour from Les Menuires by road. If you’re flying, Geneva in Switzerland is the usual option from British airports – the 90-minute flight from London is followed by a three-hour coach transfer (much of which is pretty and alpine), or you can do it quicker if you hire a car. You're also 2.5 hours from Lyon and two hours from Chambéry. Family ski holiday packages include flights and transfers.
