It's...ok.
It's not the nicest beach, if I'm honest, by my opinions, it's a bit of dive (and I'm not talking with a snorkel).
However, I imagine that is due to it being a nesting beach, so there is likely little you can do to it in terms of doing it up a little.
It's a nice walk from one side of the beach to the other, between Kalamaki and Laganos ( I'd say about 40 minutes but feels shorter).
I did also accidentally got chance to swim with two turtles one evening (they are huge) which was nice.
If you're in the area, it's not a bad visit - but I wouldn't make a special trip for it.
