On the second visit at Turquoise bay it was time for the drift snorkel. So you walk all the way to the south point of the first bay and then you get in the water and just go with the current over the reef. Gotta get out in time though, or you’ll be in a bit of trouble. Someone told me that the place you end up if you get dragged out by the currents (yes plural) is a tiger shark breeding ground. Exciting!
