I will raise my questions again latter (possibly)

I assume the lake you refer to is Negratin.

There are several warm springs in the area and the largest is on the lakeside and look lovely. (Banos de Zujar)
Has anyone been to these or other springs?
Can they be used naturist?
Are there other naturist opportunities around the lake?
