HELLO stayed in Clarys Plage campsite 5 yrs ago ..very happy with holiday there .kids older now'16,13,11...looking for recommendation .prefer fly/drive but will use ferry if drive not too bad.
Camping-Lasirene.fr is a great site near Argeles sur mer. It is particularly good for the age range of your kids. Flights to Perpignan, carcassone, Beziers and Girona in norther spain. This site has great facilities but is on the expensive side 1
Friends of ours have teenagers and recommned La Baume and have returned many times, flying into Nice. We loved Soleil Plage, near Sarlat in the Dodogne.. www.soleilplage.fr Great site.
