For divers the true treasures around Phu Quoc Island are hidden underwater where the panorama bursts into a virtual array of colours and corals. The warm, nutrient rich water draws vast schools of tropical fish. The diverse underwater scenery, and abundant marine life combined with good visibility will delight underwater photographers, marine naturalists and holiday makers alike. The calm and warm waters around Phu Quoc also make for a relaxing adventure for the experienced or first time diver and even people wishing to take advantage of the perfect snorkelling conditions.
There are some dive sites around the north of Phu Quoc but most dive trips head to the pristine reefs of both hard and soft corals that teem with colorful fish around An Thoi.
Nice reasonably shallow dive sites are numerous but don’t expect to any manta rays or large pelagic fish. Dive centers can be found easily around the island.
Phu Quoc’s crystal clear waters offer some of Vietnam’s best snorkelling. Reefs fringe many of the islands and islets that make up the archipelago and snorkelling tours run daily during high season and will show you underwater habitats full of life and colour.
The An Thoi archipelago consists of 12 islands located due south of Phu Quoc with pristine scenery and an abundance of colourful reef fish, daytrips here often include a spot of fishing.
