For those looking to be active on the island, Rainbow Divers offer excellent opportunities for snorkelling and scuba-diving; and it is highly recommended that you rent a scooter or moped for your time on Phu Quoc, as it has to be the coolest, easiest way to zip around the place. The best time to visit the island is in the dry season, which lasts from December to May. Make sure you see Phu Quoc while it is still so underdeveloped and paradisal - Phuket used to be the same way, apparently.
