We have been here a few years and haven't been able to figure this one out either.

We are used to camping in the US which is somewhere between total wild camping and what we find here in campsites. in the US you pay a small fee and choose a site, and they are often in the middle of nowhere with no one "running" the campsite and you just put money in a box. The sites are by rivers and lakes and you are allowed to build a bonfire to cook and keep you warm.

Here the campsites are more like camping in someone's back yard or on a soccer field! Sometimes we couldn't even use our charcoal grill and we had to eat canned food. They were also between 30-50 euros a night in the summer!

Let me know what you find.
