Don't try to rent tanks at the Sheraton Kiosk after 3pm. They would not rent a tank at 3:30pm though they were open to 5pm. The staff that day at the kiosk did not appear to be very SCUBA knowledgeable. Great snorkel spot for turtles out around the bend of the reef. Turtles stay down low until they need air and surface right by you. A little north to south current in this area also. Lessened around the southern turn toward the shore. Watch out for cliff jumpers and divers.
