Crazy experience that is a mist if you even go to the Cayman Islands. You can book this straight from the port, and you get in a boat that take you in the middle of the sea. It is like a sand dune in the middle of the ocean, which is no deep so you can actually stand on you feet. Then you get pretty close to stingrays (and by pretty close I mean litterally on you). The stingrays, while not dangerous, can get a bit agressive and come at you, and I must admit I was scared at first (being a 10 years-old boy at the time). But after getting used to it I really appreciated the experience and which I could do it again!
