Phu Quocβs diving is centred on the An Thoi Archipelago at the islandβs southern tip. The reefs here are the most intact on the island - the north has been affected by development and boat traffic. Visibility and coral coverage are reasonable but not comparable to the Coral Triangle or even to Nha Trangβs Hon Mun Marine Reserve.
An Thoi Archipelago dive sites
Hon Thom (Pineapple Island): The most commonly visited island in the archipelago. The reef system on the east side has good coral coverage in 5β20m depth. Suitable for all levels.
Hon Dam: A small island with a wall dive on the north side. Depths to 30m. Good fish life including grouper, snapper, and occasional barracuda.
Hon Roi: A site known for soft coral in moderate depths (10β18m). Less visited than Hon Thom, which means less anchor damage.
Finger Reef: A reef system between islands rather than at any single island. Good variety of hard coral. Occasional turtle sightings.
Marine life
The Gulf of Thailand is shallower and warmer than the South China Sea. Species include reef fish (parrotfish, angelfish, triggerfish), moray eels, sea turtles (Hon Thom area), nudibranchs, and juvenile reef sharks. No regular big pelagic sightings reported. The diving is reef-focused rather than macro or pelagic-focused.

Consistent safety standards. 2-dive boat trip: β«800,000β1,400,000 ($32β56). PADI Open Water: β«5,000,000β7,000,000 ($200β280).

Johnβs Tours: A smaller, longer-established operator with positive reviews for personal service. 2-tank dives from β«700,000 ($28).
Vietnam Explorer: Another reputable option. Runs combination snorkel/dive day trips.
Conditions
Best months: NovemberβApril. Visibility 10β20m in good conditions. Calm surface conditions make the 45-minute boat ride to An Thoi comfortable.
MayβOctober: Southwest monsoon. Reduced visibility (3β8m on bad days). Rough surface conditions. Some operators reduce schedule or cancel. Diving is still possible in calmer periods but conditions are unpredictable.
Snorkelling
Island hopping day trips (β«350,000β600,000 / $14β24 per person) include snorkelling stops at the An Thoi reefs. Equipment provided. The snorkelling at Hon Thom and the fringing reefs is reasonable - good for reef fish and coral viewing in clear conditions.
If snorkelling is the primary goal, a private boat to one reef site (β«1,500,000β3,000,000 / $60β120) with a guide who knows the good coral areas gives a better experience than a large group day trip.
Dive courses
PADI courses are available from Rainbow Divers and other operators. The Open Water course (3β4 days) can be completed entirely around Phu Quoc. Confined water sessions in hotel pools followed by open water dives in the archipelago. The conditions are suitable for training - calm and warm in dry season.
