There’s a reason why visitors come in droves from November to May, and why resorts raise their rates then. It’s because during those months the waters surrounding the island become limpid and ideal for diving and snorkelling. Some visitors snorkel optimistically in front of resorts on Ong Lang Beach, but the best locations are around the An Thoi Islands to the south or Turtle Island off the northwest coast, both of which can be visited by boat trip from Phu Quoc. At these reefs – the former of which is rated by some as the best dive site in Vietnam – you can float above brain and fan corals, watching parrot fish, scorpion fish, butterfly fish, huge sea urchins and a host of other marine life.
