Full disclosure I didn't actually swim at this beach but I spent an hour or so here because it's actually a huge beach! The internet says it's one of the most famous ones and I can see why - the water is crystal clear, bright blue (as are most of the other national park beaches lol). It's spacious though, and in addition to the beach itself, there is a snack vendor area where you can buy lunch (like sandwiches and drinks), and a gear rental place for snorkeling etc. They also have a small restaurant adjacent to the campground cafeteria area which does breakfast and dinner (but not lunch). They have pretty clean bathrooms and showers too, and the most parking of all the beaches that I went to. They even had an info booth; the lady there was fairly knowledgeable about the park although I don't think she was an actual ranger (she wasn't in the ranger outfit).
There's also a little area right at the entrance to the beach that is part of some ruins, it's a nice photo op spot. Overall this is a great beach! Def recommend. read more
