I went on a dive somewhere near Play Del Coco where the reef sharks all laid on the ocean floor because the water was so oxygenated. But I don't know the name of the dive site it was close to a small island. Does anyone know the name and who can I book with to do it again. I was staying at the RIU but can't remember if I went with their dive shop there or the one in Playa Flamingo. It was at least 3 years ago that I dove there.
