This is a perfect way to spend three hours of the day. The tour usually departs from Store Bay at 10.30am. You get to see the coral and fishes as you pass over the reef. Then you anchor and get to snorkel. It's really great the amount of different fishes you get to see, and the different coral. After that you move on to the Nylon pool, not sure why its called that, but essentially you're in the middile of the ocean and the sea is only waste deep, its truly magical.
