Recommendations of Nudist camps in Europe

Hi,

I am a single male nudist and am hoping to visit a nudist camp in Europe next month (August).

I am looking for:

- a place with a lot of space to relax and explore nude in nature
- in France, Spain, NL or Germany
- not extremely busy but more relaxing
- welcoming to single male travellers

Does this community have any recommendations?

Thank you very much

Adam
