Currents are mild, so you can take your time. Turtles are the real draw here, with green, loggerhead, and hawksbill turtles all commonly encountered. Eagle rays and bull rays cruise the sandy areas, while whitetip and blacktip reef sharks patrol at a relaxed pace. Dolphins and manta rays appear on occasion. Watch for jellyfish, particularly during warmer months, and check conditions locally before your trip.
