In reply to tomaszsvd:
i live just down the valley from Ailefroide about 20 mins away,
in terms of a car no you don’t need one, there is a really nice campsite in the valley and most (all) of the granite climbs are an easy walk from there,
there is a small supermarket just up from the campsite and a very nice bar just past that, you can get a weather forecast at the guides hut as well, there is one good climbing shop, and a great little cafe (these guys stay open just about year round, when it is shut off in the winter and everywhere else there has shut so support them if you can)
as for getting to the area car free, fly to Turin you get a bus to the porta nova train station and then a train ouix, from there you can get a bus to briancon, from there you have some options?
having said that a car will give you access to some other great climbing there are about 73 single pitch and multi pitch sports crags or sectors, granite, limestone and conglomerate rock types. Plus lots of big alpine climbing and big wall rock climbs in the Ecrins and the massive Ceres (this places rocks)
as well as a lots of via ferrata's
