Last week I have been cycling through my home country (Netherlands), mostly camping on so called "nature camping sites" (natuurkampeerterreinen in Dutch). These are quite minimalistic camping sites, mostly located in nature/forests, with only very minimalistic facilities like a few showers/toilets, but with spacious plots which provide some quietness/privacy. As wild camping is forbidden in the Netherlands, this feels like the closest (legal) alternative to camping out in nature**
There is a foundation which manages an overview of these sites, which is convenient for planning trips. I have been searching for similar foundations/organisations/overviews for other western European countries (Germany, Belgium, France, ...), but didn't manage to find any.
Does anyone know if these exists for other (western) European countries?
I know that some European countries (like Sweden, Norway, Ireland, ...) allow wild camping, and although that potentially sounds nice for the future, I am for now mostly interested in camping sites which provide at least a toilet/shower/water.
** There is one alternative called "pole camping" ("paalkamperen" in Dutch), where you are allowed to camp for free within a 10 meter radius around some pre-designated spots marked by... a pole.
