We are heading to North Spain in August in our Camper with two small children and looking for recommendation of places to camp. As we intend to move around a bit, I wan't to stay only 3 nights in each camp site and I am finding a lot of the campsites have a min 7 days booking. Can anyone recommend campsites which my take shorter bookings, we hope to stay walking distance from beaches and restaurants. Also a lot of the web sites show quite built up and packed sites, are there any which are a bit more chilled out??
