Is Phu Quoc good for scuba diving?
Phu Quoc is one of Vietnam’s top destinations for scuba diving, known for its calm waters, colorful coral reefs, and rich marine biodiversity. The island is home to nearly 400 species of hard coral along with diverse soft coral ecosystems, creating stunning underwater landscapes for divers to explore.
Scuba diving in Phu Quoc is mainly concentrated in two areas. The northern waters are famous for octopus sightings and peaceful dive sites, while the southern islands feature vibrant coral gardens and diverse marine life. With clear visibility, beginner-friendly conditions, and tour prices ranging from 900,000 VND to 1,500,000 VND per person, Phu Quoc offers memorable diving experiences for both new and experienced divers.
Best Scuba Diving Spots in Phu Quoc
Where does the magic happen? Most scuba Phu Quoc trips head south to the An Thoi Archipelago.
An Thoi Archipelago
This chain of 15+ islands offers the best visibility and dramatic rock formations.
-
Turtle Island: Famous for hard corals and diverse reef fish.
-
Location: An Thoi Ward, South of Phu Quoc City, An Giang Province (Boats depart from An Thoi Port).
-
Nudibranch Gardens: A macro photographer’s dream, teeming with colorful sea slugs.
-
Depth: 5m – 20m (Great for Open Water divers).
Hon Thom isn’t just a cable car destination – it’s also a diver’s playground. Dive sites here are teeming with life: schools of fusiliers, lionfish, and soft corals decorate the reefs. The currents are usually mild, which makes this site great for those looking to gain confidence in open water.
Hon Roi
For divers who like a bit of mystery.
-
Highlight: Rocky slopes and submerged boulders.
-
Location: Hon Thom Commune, Phu Quoc City, An Giang Province (Accessible via Sun World Cable Car or boat).
-
Conservation: Reef health is improving rapidly thanks to local protection efforts.
The reef health here is improving steadily thanks to recent conservation efforts, and dive conditions tend to be excellent during the dry season. Bring a flashlight – the crevices hold surprises.
Phu Quoc’s Best Dive Beaches and Reefs
For those preferring shore dives or quick half-day trips, Long Beach and Ong Lang Beach offer surprisingly good snorkeling and shallow diving opportunities. While the coral may not be as dramatic as in An Thoi, the calm waters are great for beginners and training dives.
As a local guide, I often take new divers here for their first underwater breaths. It’s a calm, confidence-building start to the scuba Phu Quoc experience.
Best time for scuba diving in Phu Quoc
The diving calendar is tightly tied to the broader weather patterns of the island. Our guide on the best time to visit phu quoc island vietnam covers the full seasonal breakdown, but the short version for divers is: plan for November through May. These months combine the lowest rainfall, the calmest seas and the highest visibility windows, and all dive operators run full daily schedules without weather cancellations.
June through October is technically possible but unpredictable. Operators in An Thoi typically reduce departures and cancel outer-island trips at short notice when south-westerly winds kick in. Visibility can drop to 5–8 m after heavy rain due to river runoff. If you must dive in this window, stick to inner-reef sites like Hon Roi and Bai Cau Lam, which are more sheltered.
Month-by-month dive conditions
- November–January: best visibility (15–22 m), coolest water at 26–27°C, whale shark season peaks.
- February–April: warm water 28–29°C, stable conditions, busy with international divers – book operators early.
- May: shoulder season, still good diving before monsoon builds.
- June–October: green season – unpredictable, inner-reef only, reduced schedule.
Dive Schools, Operators & Costs in 2026
A cluster of established dive centres operates out of Duong Dong town and from the An Thoi pier area. Most are PADI-affiliated and can process Open Water, Advanced and Rescue certifications within the standard 3–4 day courses. Always verify that your operator has current PADI membership, check that cylinders have valid hydrostatic test dates, and confirm that the boat carries a first-aid oxygen kit.
Price benchmarks for 2026 vary by operator and group size. A Discover Scuba Diving (DSD) day typically runs 1,800,000–2,200,000 VND (~$72–$88 USD) and includes two introductory dives, equipment and a guide in the water with you throughout. An Open Water certification course runs 6,000,000–8,500,000 VND (~$240–$340 USD) over three to four days. Fun dives for already-certified divers are priced at 650,000–900,000 VND per dive, with most operators offering discounts from the third dive onwards.
What to look for when booking
- Maximum group size per instructor: PADI recommends 8 students per instructor for Open Water.
- Boat condition and life-saving equipment – oxygen kit, first-aid, emergency contact procedure.
- Nitrox availability for deeper dives (25 m+) and longer bottom times.
- Pick-up from your resort – many operators offer complimentary transfers from the Bai Dai area.
Tips for a Safe and Memorable Scuba Trip
Staying safe ensures every dive is enjoyable. Here are my top professional tips from the Corona Resort dive team:
Pre-dive Preparation and Gear Checklist
Before heading out:
- Ensure your dive certification is valid (Open Water or above for most sites).
- Inspect your gear: regulator, BCD, mask, fins, wetsuit.
- Hydrate well and avoid alcohol the night before.
- Get a refresher if it’s been over 6 months since your last dive.
Local dive centers on the island (like the one at our Corona Resort) offer excellent rental gear and check-ups to keep your scuba Phu Quoc journey smooth and safe.
In-water Safety and Marine Conservation
Always dive with a buddy and follow your guide. Avoid touching coral or chasing marine life – it’s not only harmful but can also ruin the ecosystem for future divers. Here in Phu Quoc, we’re working hard on marine restoration projects, so every diver plays a part. Bring reef-safe sunscreen and avoid plastic. Be a proud ocean ambassador.
Choosing Certification: PADI vs SSI
Both PADI and SSI offer high-quality dive training, and both are recognized globally. On Phu Quoc, you’ll find certified instructors for both agencies. PADI is slightly more widespread, while SSI often provides flexible learning modules and slightly lower prices.
For most travelers, either works perfectly for enjoying the full scuba Phu Quoc experience. I recommend chatting with your instructor to find the best fit.
