We stayed there, but just overnight, a couple of years ago. It has very big pitches, quite shady, and easily accessed. The pool area is OK (not as big as it looks in the photos). There's a small bar, restaurant and take-away, with a limited menu. The toilet blocks are clean but the shower cubicles are very small indeed. It's a long walk into the nearest village which has a couple of bars and a small supermarket.
We were there in late August and it was VERY quiet. If I'm perfectly honest it isn't the sort of site I would take teenage boys to. It's a long way from the village, and it isn't a site with a lot to keep them interested. I had teenage boys myself once. We stayed at Dugny to meet one of them, then aged 25, and recover our camping equipment which he had borrowed to go to Biarritz surfing. He and five other large young men managed to stay in two tents on an adjacent pitch to us, together with their cars and motorbikes.
Opinions may differ on this site, however, and I suppose all teenage boys are not alike and some want different things to others.
