Perfect beach, but no overnight: 36.860944, -2.006636
This beach is beautiful. Always a handfull of campers around, but strictly no staying overnight. The ranger is checking at 19:30 (which was sunset) and giving a friendly reminder to leave. But police is enforcing him, as a view other campers confirmed, who had tried to sneak back in later.
I went further to Cala del Plomo for the night, which is about a 15 km drive north
