This is a MUST do if you are on the island and I canāt recommend Captain David and his crew enough! One of the nice things about their operation is the size of the boat as it allows you to bring a packed change of clothes and also had a restroom (key for your wife, daughter, etc.). Captain David and his crew are incredibly knowledgeable of the rays, how to find them and the importance of protecting their environment. If you get cold in the water after a short while you can wait on the boat until the rays arrive and then jump in.
