The beach itself is kind of gross. I really wanted to love it but... no. It's too rocky, there's weird algae and moss, dog crap, all kinds of rubbish everywhere and we even found dead birds by the beach. I don't know how some people can go swimming in there, even the thought of it makes me gag. I'd probably shower in chlorine afterwards.
Good pokemon hunting spot though, but not by the actual beach but on the camgrounds... IF you can get internet to work. My LTE barely worked.
