Le Corbier Ski Resort
For purpose built convenience, great value and low prices, Le Corbier is a good choice.
If you're looking for a large linked ski area, but don't want to break the bank, the Les Sybelles ski area (linked with nearby La Toussuire) offers up 310km of pistes at a much cheaper price than its near neighbour the Three Valleys. Three fast chairs serve a decent network of snowsure blues and reds above the resort base, before lifts (most of which are unfortunately slow) fan out towards La Toussuire or in the opposite direction towards St Sorlin d'Arves. There's some longer runs off the ridgelines down to the villages, as well as some decent off piste if conditions allow. Snow reliability is usually good.
The resort itself is fairly brutal to look at, with high rise apartment blocks dominating the skyline. This does mean however that most accommodation is not only good value, but is centrally located right at the foot of the slopes – that convenience is worth the price of the resort aesthetics. Food and drink is cheaper than at most French resorts, plus you'll save on things like ski hire too. Getting here is simple, with the drive up the Maurienne Valley taking around 2 hours from Geneva.
