We went camping with vacan solei, the tent was just great. The place is less beautiful then you imagine. Think of a small child that cannot walk yet and then from the tent you get your feet into sand immediately. This is not very child-friendly, we had expected real grass. Entertainment for the children was only in French, and there was nothing to the disco, bedtime stories, musical etc.
Location is at a beach with boulder, someway further, however, there is a sand beach but then you must find your way through seaweed etc. However, there are small pools of water for the kids.
Village is not great, however, there are nice places in the area.
Our first time in the Vendee, but to us, this is not the bit of France we had imagined.
However, very pleasant people/staff.
