2. Northern Phu Quoc Dive Sites
The northern waters of Phu Quoc offer a selection of relatively shallow sites that are particularly attractive to beginners, snorkelers and travelers who want to enjoy colorful reefs without going to great depths.
Turtle Island (Hon Doi Moi)

Turtle Island, also known as Hon Doi Moi, is considered one of the notable diving and snorkeling locations in northern Phu Quoc, a few kilometers offshore from Bai Dai Beach.
A large coral area can be found at a very shallow depth of around 0.5 meters, making the site accessible to snorkelers. Divers who descend to approximately 10–12 meters can explore attractive hard-coral formations and encounter a variety of tropical fish, including damselfish and stonefish.
The combination of shallow coral areas and deeper sections makes Turtle Island suitable for visitors with different levels of underwater experience.
Fingernail Island (Hon Mong Tay)

Fingernail Island, or Hon Mong Tay, is another popular northern site for snorkeling and recreational diving. It is particularly suitable for travelers looking for a relaxed underwater experience rather than a demanding dive.
The area features large rocks scattered across a relatively flat sandy bottom. These rocks provide natural hiding places for marine creatures such as barracudas and giant pufferfish. Divers can also discover a mixture of hard and soft corals.
The sandy seabed is equally interesting for those willing to look closely. With patience, divers may spot smaller creatures such as octopuses, mantis shrimps and toadfish hiding among the rocks and sand.
Nudibranch Garden

As its name suggests, Nudibranch Garden is an excellent site for observing colorful nudibranchs and other small marine creatures. With a maximum depth of approximately 12 meters, it can be suitable for divers of different experience levels.
The site features shallow reef areas as well as larger coral and rock formations in deeper sections. Some of these formations provide shelter for marine animals, including bamboo sharks.
For underwater photographers and divers who enjoy searching for small marine life, Nudibranch Garden can be particularly rewarding.
3. Southern Phu Quoc Dive Sites

The southern waters of Phu Quoc are home to the An Thoi Archipelago, a group of islands located off the southern tip of Phu Quoc. The archipelago consists of 15 islands and is known for its clear tropical waters, coral reefs and diverse marine ecosystems.
Many of the area’s popular diving and snorkeling sites are relatively shallow, generally less than 12 meters deep. Divers can encounter schools of small tropical fish, sea-grass areas, gently sloping coral reefs and a variety of other marine creatures.
The southern islands therefore provide a diverse setting for both snorkeling and recreational diving.
Hon Thom Island

Hon Thom is the largest island in the An Thoi Archipelago and is surrounded by several diving sites. One of the notable locations is Pineapple Point, which has different underwater environments on its northern and southern sides.
North Pineapple Point features coral reefs, whip corals and abundant cuttlefish, offering divers plenty to observe as they explore the reef.
South Pineapple Point, by contrast, reaches a depth of around 35 meters, making it one of the deeper dive sites around Phu Quoc. Strong currents can occur in this area, creating more challenging conditions that are better suited to experienced divers.
Dragon Rock

Dragon Rock is regarded as one of the notable dive sites around Phu Quoc, with a maximum depth of approximately 15 meters, depending on tidal conditions.
The underwater landscape is dominated by large boulders, some reaching the size of houses, creating an impressive environment of rocks, corals and marine life.
Divers may encounter different species of angelfish, along with numerous reef fish, crustaceans and a wide variety of hard and soft corals. The combination of dramatic rock formations and colorful marine life makes the site particularly interesting to underwater explorers.
Dry Island

Dry Island offers a distinctive underwater landscape because the island itself has little or no vegetation. Beneath the surrounding waters, however, visitors can discover an extensive reef system filled with marine life.
Among the species that may be encountered are Moorish idols, butterflyfish, bamboo sharks, rays, catfish, nudibranchs and scorpionfish. Divers can explore around the island’s rocky formations and keep an eye out for cuttlefish and octopuses.
The combination of large boulders, coral reefs and marine creatures makes Dry Island an interesting location for recreational diving.
Roi East Island

Situated between the island’s coastline and an offshore pearl farm, Roi East Island is another relatively shallow dive site. With a maximum depth of around 10 meters, it can accommodate divers looking for an easier underwater exploration.
The site is home to a mixture of larger and smaller marine creatures. Divers may spot moray eels and sweetlips alongside hermit crabs, cuttlefish and glass shrimp.
The surrounding coral formations also provide plenty of opportunities to observe tropical marine life at close range.
4. Best Time to Dive in Phu Quoc

Phu Quoc enjoys warm tropical waters throughout the year, with sea temperatures generally ranging from around 28°C to 31°C. This makes the island suitable for water activities in different seasons.
However, the dry season from November to April is generally considered the most favorable period for diving. During these months, travelers can typically expect sunnier weather, less rainfall, calmer seas and better underwater visibility.
Weather and sea conditions can still vary, so divers should check local conditions and follow the recommendations of their chosen diving center before heading out.
5. Useful Advice for Diving in Phu Quoc

Whether you are an experienced diver or are planning your first underwater adventure, a few practical preparations can make your trip more comfortable and enjoyable.
- Diving equipment: Diving centers generally provide the necessary snorkelling and scuba-diving equipment. Travelers should bring suitable swimwear and, if desired, a waterproof camera or underwater camera to capture their experience.
- Follow your guide’s instructions: Both beginners and experienced divers should carefully follow the instructions of professional diving guides. Local guides can provide important information about sea conditions, currents, dive routes and safety procedures.
- Choose a suitable site: The northern areas, with their relatively shallow waters, can be suitable for inexperienced divers and beginners. More challenging sites, particularly those with greater depth or stronger currents, are better suited to experienced divers.
- Prepare for seasickness: Some dive sites require a boat or speedboat journey from the coast. Travelers who are prone to seasickness should consider bringing appropriate medication and taking precautions before departure.
- Non-divers can participate too: You do not necessarily need to be a certified diver to enjoy Phu Quoc’s marine environment. Many tour operators offer snorkelling and introductory experiences, meaning non-swimmers and first-time visitors may have options available depending on the tour and safety conditions. Snorkelling is especially accessible because it does not require scuba-diving certification.
Discover Phu Quoc Beneath the Surface

Phu Quoc offers much more than beautiful beaches and tropical sunsets. Beneath its warm turquoise waters lies another side of the island, where colorful coral reefs, tropical fish, rock formations and fascinating marine creatures create a memorable underwater experience.
From the shallow reefs of the northern islands to the diverse dive sites around the An Thoi Archipelago, visitors can choose experiences that match their interests and diving abilities. Whether you are trying scuba diving for the first time, enjoying a relaxed snorkelling trip or looking for new underwater landscapes to explore, Phu Quoc offers an exciting way to experience Vietnam’s tropical island beauty from below the surface.
