Spend a day diving the An Thoi Islands off southern Phu Quoc: two guided certified dives, lunch aboard a wooden boat, and transfers from Duong Dong. Expect warm water, colorful reefs and straightforward logistics suitable for experienced divers.
More ways to explore the area's outdoor wonders
You step from the pier into warm, saline air and the wooden boat rocks gently toward a chain of karst-formed islets off southern Phu Quoc. The An Thoi archipelago pulls you into clear water where staghorn coral and low, rounded bommies rise like underwater cliffs. Below the surface, colors sharpen—parrotfish graze, and reef structures spread in bands of orange and mauve.
