Cool! My favourite beach on that coast.
It does get REALLY busy though, which can be a bit annoying if you want some space.
Times I've been there wasnt a security guard and was no age restrictions on who could visit, were a few families etc so dont think that rule is right
Your right ... There's been folk of all ages there everytime I've been and don't recall ever seeing any age limit signs. I think adding the over 18 only to the video gives it seedy overtones, which it certainly isn't. It's a great beach for everyone.
I have seen them politely enforce the nudity rule though, which I think is a great thing IMO.
