In reply to Herdwickmatt:
there is a nice camp site in les Vigneaux, just down the road form Ailefroide and Vallouise, it's split in two,
the upper one is on one side of the road has a pool, restaurant, bar etc, camping le courounba
the other side (lower) Le camping LES VAUDOIS is basic and more chilled with spots in the woods with an alpine river running through,
plenty of running and walking near by plus some good swimming lakes, and even a nice place you can feed the marmots for the little one, lots to do for a family.
I live just above the lower site happy to help if you would like more info.
