About Sao Beach
The south coast of Phú Quốc, Vietnam's largest island in the Gulf of Thailand, curves into Bãi Sao – a three-kilometre crescent of powder-fine white sand whose grains gave the beach its Vietnamese name, literally star beach. Five kilometres east lies Bãi Khem, a twin south-coast cove of equally fine sand, while the west coast's twenty-kilometre Long Beach, or Bãi Trường, draws sunset crowds. Sea temperatures hold a steady 28–29 °C from November to April, the dry-season window, with Phú Quốc International airport thirty minutes by road.
