Diving & snorkelling in Phu Quoc 2026: dive sites, prices, centres
Phu Quoc's waters hold 108 coral species and rank among the most budget-friendly dive regions on earth. A group snorkel tour starts from about $20, and a scuba try-dive from around $80 with transfer, gear and lunch. Beginners without a certification and experienced divers alike come here — from the An Thoi archipelago in the south to the quiet northern islands.
This guide covers the specific dive sites in the south and north of the island, a comparison of dive centres with English-speaking PADI instructors, a seasonal calendar, 2026 prices in USD, and a gear checklist.
Prices and conditions are current as of March 2026. Exchange rate: 1 USD ≈ 25,000 VND.
Is Phu Quoc worth it for diving and snorkelling?
Phu Quoc is not the Maldives or the Red Sea. Visibility is more modest here (3–20 m against 30–50 m), and the marine life is less exotic. But it is well worth coming for the underwater activities if you want a budget entry into diving, or plan to pair snorkelling with a beach holiday.
The An Thới archipelago in the south is 15 islands with twenty dive sites and coral gardens that start at half a metre deep. To the north lie quiet islands with nudibranchs and barracuda. And the clincher: a PADI Open Water Diver course here runs $350–430, whereas in Thailand it is from $400 and in Egypt from $350 — and Phu Quoc rarely fills up like either.
Who Phu Quoc suits best:
- Beginners — try-dives from $80, English-speaking instructors and warm water year-round (26–30 °C)
- Families with kids — shallow snorkelling at Gam Ghi (down to 2 m); children from age 8 are allowed on dives
- Budget travellers — a group tour to the southern islands from $20 with lunch
- Certified divers — 20+ sites, night diving, macro photography
A couple of honest downsides. Visibility on some southern sites can drop to 3–5 m even in the dry season — Half-Moon Reef, for one, is temperamental. And the $20–25 group tours pack 30–50 people onto a single boat, so an intimate outing is not guaranteed. If crystal visibility and big pelagics matter to you, look towards Côn Đảo or the reserve off Nha Trang instead.
That said, Phu Quoc's attractions combine brilliantly with diving for a full week's programme. A morning dive at Dragon Rock, an afternoon at Vinpearl Safari, an evening at the Dương Đông night market.
The best snorkelling spots in Phu Quoc
Snorkelling in Phu Quoc concentrates in two zones — the An Thoi archipelago in the south (15 islands, rich coral, 15 minutes by boat) and the northern islands (quiet, intimate, clear water). The south is brighter and more varied; the north is calmer and closer to untouched nature.
An Thoi archipelago — the southern islands
The starting point is An Thới port at the far south of Phu Quoc. It is a 30-minute drive from Dương Đông (the island's centre). The boat takes 15–20 min to the nearest islands, 30–40 min to the far ones.
Gam Ghi Island — shallow water, averaging under 2 m deep. Coral starts right at the shore: brain coral, table, tube, mushroom and cabbage forms. The ideal spot for beginners and children — you can float without fins and see the reef from the surface. The water is warm (28–30 °C) and currents are weak.
May Rut Island (Coral Park) — the jewel of the archipelago. Over 250 species of hard and soft coral across an area the size of two football pitches. It is 5–15 m deep, but snorkelling works on the shallower stretches near shore. Clownfish tucked into anemones are a common sight. The most photogenic spot in the archipelago.
Hòn Thơm (Pineapple Island) — a mix of snorkelling and diving. Deeper than Gam Ghi (10–25 m), with varied coral structures. You can reach it on the Hòn Thơm Cable Car (the world's longest over-sea cable car at 7.9 km) and then continue by boat to the reefs.
Hòn Mây Rứt Ngoài — the outer May Rut island, less visited than its "inner" neighbour. The bonus is a snow-white sandy beach with almost no one on it.
The northern islands
Hòn Đồi Mồi (Turtle Island) — a tiny islet just 50 m long with coral from half a metre deep. The water is clear and currents are minimal. A large stretch of coral sits at 0.5 m, so children can watch it straight from the surface. A few palms on shore, a scrap of sand — and a full sense of a desert island.
Hòn Móng Tay (Fingernail Island) — a crescent-shaped island of white sand, named for its resemblance to a fingernail. Underwater are rock formations whose crevices hide barracuda and giant pufferfish. One of the quietest places in Phu Quoc.
Nudibranchs are this spot's calling card. These bright sea slugs, 1–5 cm across, look like underwater graffiti: neon, striped, horned. If you shoot macro, Fingernail Island is a must.
Bãi Thơm — the north-east coast of Phu Quoc. Crystal-clear water, tropical fish, coral formations in the shallows. Reach it by boat from Bãi Thơm beach in 10–15 min.
Shore snorkelling — where you can go without a boat
Shore snorkelling in Phu Quoc is limited — the main coral reefs sit off the far islands. But there are two spots:
- Kỳ Lân Cape on Hòn Thơm island — shallows from 1 m, coral visible from the surface. Entry is free, but you can only reach Hòn Thơm by cable car (a ticket is around 600,000 VND / ~$24)
- Starfish Beach (Rạch Vẹm) — live starfish in the shallows. There is no coral, but the sight is striking: hundreds of red, orange and turquoise stars on the sandy bottom. Touching the starfish is forbidden — it kills them
On the main island's beaches (Bãi Dài, Long Beach, Ông Lang) there is almost no coral. For proper snorkelling you need a boat.
Dive sites in Phu Quoc — where to descend
Phu Quoc's main dive sites sit off the An Thoi archipelago — depths from 5 to 40 m, with coral cover for every level. The northern sites are shallower and simpler, the southern ones deeper and more varied. There are around 20 sites in all, but only 10–12 are used in practice.
| Dive site | Depth | Level | Highlights |
|---|---|---|---|
| Gam Ghi Island | up to 2 m | Beginner | Shallows, 6 coral types, photo diving |
| May Rut (Coral Park) | 5–15 m | Novice | 250+ coral species, clownfish in anemones |
| Dragon Rock | 10–20 m | Intermediate | Giant boulders, underwater maze |
| Hòn Thơm | 10–25 m | Intermediate | Varied structures, rarely — turtles |
| Half-Moon Reef | 5–15 m | Novice | Crescent reef, visibility 3–8 m |
| Dry Island | 5–15 m | Novice | Gentle slopes, sea fans |
| Turtle Island (north) | 0.5–5 m | Beginner | Family diving, minimal currents |
| Fingernail Island (north) | 3–10 m | Novice | Rock formations, nudibranchs, macro |
Dragon Rock — the underwater maze
The most striking site for intermediate divers. Huge boulders stacked on one another form an underwater maze of passages and "rooms." Between the rocks are gorgonians (sea fans) and shoals of tropical fish. It is 10–20 m deep, and currents can pick up when the tide turns. A dive lasts 35–45 min. One caveat: the boulders make navigation harder than on open reefs — go with an instructor the first time, even if you hold an OWD.
May Rut (Coral Park) — for underwater photography
Phu Quoc's signature site. A coral garden at 5–15 m with soft and hard coral in every colour. If you have a GoPro, start here. The best time to shoot is the morning, when the sun cuts through the water.
Dry Island — for a first dive
Gentle coral slopes with sea fans. A calm site for a first dive: even terrain, steady visibility, depth to 15 m. This is often where people put on a tank for the very first time.
For night diving, ask at the dive centres — not all offer it, but Flipper Diving and Rainbow Divers occasionally run night dives off the southern islands. At night out come cuttlefish, octopus and shrimp — a completely different world.
Skip the airport queue in 5–10 min
In winter, immigration lines run 60–90 min. With Fast Track you’re met at the aircraft and taken through the priority lane. Arrange it before you fly.

Phu Quoc dive centres — which to choose
Phu Quoc has 6–7 dive centres. When choosing, look at three things: PADI status (5-star = the safety standard), whether they run English-speaking groups, and the area — southern or northern sites.
| Centre | Status | English | Area | What stands out |
|---|---|---|---|---|
| Flipper Diving Club | PADI 5☆ IDC | Yes | South + North | Oldest PADI 5☆, eco-focus |
| Rainbow Divers | PADI | Yes | South + North | Since the 90s, daily trips |
| Vietnam Active | PADI 5☆ | Yes (main) | South | Aqualung gear, English-speaking groups |
| Tortuga Diver | PADI, NDL, CMAS | Yes | South | Multiple cert systems, kids from 8 |
| Seamen Divers | — | Yes | South | Comfortable boat, personal approach |
Flipper Diving Club
The pick if reputation and international certification matter to you. PADI 5 Star IDC Resort is the top status in the PADI system, meaning it can train instructors. Flipper has run since 2009 and leans hard on ecology: no touching coral, reef-safe sunscreen only, minimal litter at the dive sites.
"If you dive in Phu Quoc, make it Flipper Diving Club." — guest review on TripAdvisor, 2025
Vietnam Active
A PADI 5-star centre running mainly English-speaking groups, kitted out with Aqualung gear. A good fit if you want a certified international operation and clear briefings in English. They cover the southern sites and handle everything from try-dives to full PADI courses.
Rainbow Divers
An island veteran, operating since the late 90s. Daily trips both south and north, so you can pick your direction. Rainbow has some of the most experienced divemasters on the island: many have been at it 10+ years. Briefings are in English, and they can arrange multilingual guides on request.
What to check before you book
- Gear condition — masks without scratches, a regulator free of corrosion, a BCD checked before every dive
- Group size — the PADI norm is up to 4 beginners or up to 8 certified divers per instructor. More than that is a reason to walk away
- Insurance — check whether it is included. If not, arrange DAN cover or travel insurance that specifically covers scuba diving (standard policies usually exclude it)
- The boat — a covered deck, a toilet, fresh water to rinse off, space for cameras

Message the managerWhen to dive — the diving season in Phu Quoc
You can dive in Phu Quoc year-round — water temperature never drops below 26 °C. But conditions vary sharply by season: visibility ranges from 3 to 20 m, and in the rainy months swell keeps boats from reaching the far islands.
| Month | Visibility | Water t° | Swell | Jellyfish | Verdict |
|---|---|---|---|---|---|
| Dec–Feb | 10–20 m | 26–27 °C | Weak | None / few | Ideal |
| March | 10–15 m | 28 °C | Weak | None | Excellent |
| Apr–May | 5–10 m | 29–30 °C | Moderate | Appearing | Good, rash guard a must |
| Jun–Sep | 3–5 m | 28–29 °C | Strong | Many | Not recommended |
| Oct–Nov | 5–15 m | 27–28 °C | Weak | Few | Good, fewer crowds |
The ideal window is December–March. Dry season, calm sea, visibility up to 20 m at the best sites. This is also peak tourist season in Phu Quoc, so book your diving 2–3 days ahead — the popular centres fill up.
April–May is the shoulder period. The weather is still bearable, but jellyfish appear. A rash guard is a must. The upside: fewer tourists and lower prices.
June–September is the rainy season. Swell, murky water, visibility down to 3–5 m. If you are here in summer, choose the sheltered northern sites: Turtle Island and Fingernail Island are shielded from the south-west monsoon.
October–November — the sea calms and visibility climbs. By mid-November conditions are already good. An excellent window for anyone wanting to dodge the crowds.
Phu Quoc's marine life — what you will see underwater
Phu Quoc's waters have 108 recorded coral species and 132 mollusc species. Not a Southeast Asian record, but plenty for a vivid experience — especially if it is your first time underwater.
Coral
- Brain coral (Favia) — spherical, grooved colonies, from fist-sized to a metre across. Everywhere on the southern sites
- Gorgonians — sea fans that look like an open fan. They photograph beautifully in side light
- Pavona — leaf-like coral, flat and wide. Grows on the gentle slopes of Dry Island
- Table coral — flat "tables" up to half a metre across. Small fish shelter beneath them
- Soft coral — sponges, anemones and sea pens at May Rut. They sway in the current, creating an underwater-forest effect
Fish and marine creatures
- Clownfish (Amphiprion) — the star of underwater photos, 5–10 cm, orange with white bands. Hides in anemones and aggressively "defends" its home
- Barracuda — schooling predators up to 1 m, often passing in a silver wall. Harmless to divers — just take off shiny jewellery
- Pufferfish — round, slow, photogenic. At Fingernail Island there are giants the size of a football
- Nudibranchs — bright sea slugs 1–5 cm. Neon, striped, horned. A macro-photographer's favourite
- Starfish — hundreds of them on Rạch Vẹm beach: red, orange, turquoise
- Cephalopods — cuttlefish and octopus on night dives
What not to expect
Honestly: Phu Quoc has no manta rays, no whale sharks, no giant turtles or moray gardens. On a bad day visibility drops to 3–5 m. If you are diving straight after the Red Sea or the Maldives, calibrate your expectations. Phu Quoc is a gentle, budget, warm-water introduction to the underwater world.
Safety — jellyfish, currents and what you need to know
The main hazard for snorkellers and divers in Phu Quoc is jellyfish. They appear from April and stay until August, with occasional flare-ups in November–December.
Jellyfish species in Phu Quoc
| Species | Danger | Season | Appearance |
|---|---|---|---|
| Moon jellyfish | Mild irritation | Year-round | Clear dome 10–30 cm, bluish rings |
| Fire jellyfish | Painful sting | April–August | Pink-orange, tentacles 0.5–1 m |
| Box jellyfish | Life-threatening | Rare, June–August | Square dome, thin long tentacles |
How to protect yourself
- A long-sleeve rash guard + leggings — cover 80% of your body. Recommended always, not just in jellyfish season
- Jellyfish repellent — Safe Sea lotion or similar. Sold at dive centres
- Don't swim after rain or at high tide — jellyfish get pushed towards shore
- Follow the instructor's directions — routes are planned with jellyfish in mind
First aid for a sting
Rinse the sting with vinegar (not fresh water — it triggers the stinging cells). Remove any tentacle remnants with tweezers or the edge of a plastic card. Apply ice through a cloth. For severe pain, facial swelling or difficulty breathing, call an ambulance immediately (115 in Vietnam).
Currents and other risks
Currents at Phu Quoc's dive sites are usually weak — 0.5–1 knots. But at Dragon Rock and on turning tides they can briefly strengthen to 2 knots.
- Don't touch the coral — it is alive and fragile. A scrape takes 2–3 weeks to heal
- Don't feed the fish — it disrupts the ecosystem
- Don't step on sea urchins — the spines cause painful wounds
- Use reef-safe sunscreen — ordinary sunblock kills coral
What to bring — a diver's and snorkeller's checklist
Dive centres provide all the gear — from the mask to the tank. But a few things are better brought yourself.
Bring yourself
- A long-sleeve rash guard (protection from jellyfish + sun + coral scrapes)
- Reef-safe sunscreen (ordinary oxybenzone sunblock kills coral)
- An underwater camera or GoPro with a housing
- Your PADI certification card (or the PADI app on your phone)
- Seasickness medication (the boat rocks)
- Proof of dive insurance — DAN membership or a travel policy that explicitly covers scuba
- A zip-lock bag for wet items (and for your phone and documents)
- A towel (not every boat provides one)
- Dry clothes for the way back
- Cash for a tip for the instructor (50,000–100,000 VND / ~$2–4)
The dive centre provides
- Mask, snorkel, fins
- BCD (buoyancy compensator) and regulator — for divers
- Wetsuit (a short 3 mm — the water is warm)
- Life vest (for snorkellers)
- Weight belt
- Lunch and drinks on the boat
- Hotel transfer
"Bringing our own masks made a huge difference — the rental ones fogged up every five minutes. A cheap mask paid for itself in two trips." — guest reviews, TripAdvisor, 2025
A day of diving, step by step
Discover Scuba Diving (for beginners)
07:30–08:00 — hotel transfer. An air-conditioned minibus picks you up at the door. It is a 20–40 minute drive to An Thoi port.
08:30–09:00 — briefing on shore. The instructor explains the rules: how to breathe through the regulator, how to equalise your ears, the hand signals underwater — all in English.
09:00–09:30 — boarding the boat and heading out to the dive site. You put on the wetsuit; they fit the BCD and weight belt.
09:30–10:15 — the first dive (20–25 min at up to 12 m). The instructor leads you by the hand or stays close. The first minutes are adjustment. By the fifth you relax.
10:15–11:30 — a break on the boat. Tea, fruit, rest. The boat moves to the second site.
11:30–12:00 — the second dive. More confident now: steadier breathing, looking around, taking photos.
12:00–13:00 — lunch on the boat: fried fish, rice, salad, fruit, water.
13:30–15:00 — shallow-water snorkelling (if it is in the programme) and the return to port. Transfer to the hotel.
Snorkel tour — what "$20–25" includes
In the morning (8:00–8:30) you are picked up from the hotel and driven to An Thoi port. You switch to a wooden boat — a traditional Vietnamese one, with a sun canopy. Then it is 2–3 stops at islands: 30–40 min of snorkelling at each point. Between stops there is fishing (rods provided). Lunch on the boat: fried fish, rice, fruit, drinks. Back at the hotel by 15:00–16:00.
The downside of the group tour is 30–50 people on one boat. Noisy, cramped, little attention. If comfort matters, take a small group ($40–50) or a private tour (~$65).
"We dived with a PADI centre — patient instructor, new gear, clear English briefing. Underwater: coral, a clownfish, a huge pufferfish. Highly recommend." — guest reviews, TripAdvisor, 2025
FAQ — frequently asked questions
Can you dive in Phu Quoc if you cannot swim?
Yes, both for diving and snorkelling. On a dive the BCD keeps you afloat at the surface and the instructor holds your hand underwater. On a snorkel trip you wear a life vest. Most centres take non-swimmers on a Discover Scuba Diving session.
How much does snorkelling in Phu Quoc cost?
A group tour to the southern islands starts from about $20, including mask, snorkel, fins, lunch and transfer. A small group (6–10 people) is $40–50. A private trip is from around $65.
Where is the best snorkelling — north or south?
The south (An Thoi archipelago) is richer in coral and fish. Gam Ghi and May Rut are the two top spots. The north (Turtle Island, Fingernail Island) is quieter, less crowded and clearer. Choose the south for a first time, the north for a return visit.
Do you need a certification to dive?
Not for a Discover Scuba Diving trial. A PADI instructor gives a 30-minute briefing and dives with you to 12 m. For independent diving you need a PADI Open Water Diver — a $350–430 course over 3–4 days.
Do they take children diving?
Snorkelling from age 6, a try-dive from age 8–10. Most centres take children from age 8 on a Discover Scuba trial. The full PADI Junior Open Water certification starts at age 10.
Are jellyfish in Phu Quoc dangerous?
In the dry season (December–March) there are almost none. From April to August a rash guard is a must. Moon jellyfish are harmless, fire jellyfish sting painfully, and box jellyfish are potentially dangerous but very rare.
When is the best season for diving?
December–March is best: dry season, calm sea, visibility up to 20 m. April–May is fine, but with jellyfish. June–September is not advised due to swell and murky water.
Data current as of March 2026. Prices and conditions can change — check the dive centres' websites before your trip.
