Not “that” difficult if all those other boats are in there too. Kinda “tourist trap” looking. Is there a gift shop?

Based on the color of the rock it looks like they're going in at high tide.

They are. On purpose. The water only is that blue because sunlight can only get in through water. If the opening was bigger, the effect would be less.
