Phu Quoc Half-moon Reef (富国岛 – 半月珊瑚礁)(16 Km off An Thoi town) is one of a handful of fringing reefs (coral reefs grow on the continental of an Island) possessing a great variety of both hard and soft coral. Especially, for those who are interested in conquering waters of various depths, the Half-moon reef is absolutely an ideal destination. Underwater rocky terrain which is full of obstacles and difficult to access will definitely arouse your curiosity of discovering, searching for something special concealed under the darkening water, behind big rocks and cliffs.

Diving into the water then reaching the depth of only 3 meters down, you will be able to catch sight of soft coral-covered rocks, long cliffs, or canyon with a range of colors. You would be even more surprised at the ground of the Half-moon Reef at the depth of 6 – 8 meters as we figured out this place like a kingdom of Porites Corals or Rocky Corals with big size. But if you can’t do easy free-dive, it is not so a big deal as on good days of favorable conditions you could experience very clear underwater visibility of 4 – 5 meters. A hidden beauty awaits your exploration at Half-moon Reef.

🔖 No.2. Phu Quoc Crystal Reef (富国岛-结晶珊瑚礁)

Phu Quoc Crystal Reef (富国岛-结晶珊瑚礁) has been once considered as the paradise of corals of Phu Quoc Island with a great variety of hard coral species. Phu Quoc Crystal Reef is located 14 km away from An Thoi town, in calm water for almost a whole year.

Coming to the site, you are likely to be surprised by the clean blue water at first sight and white-sand seabed as you could see through the shallow water of 2 – 4 m here. Getting into the sparkling water with surrounding coconut trees under mild sunshine, on the seabed covered with full of hard coral species, you see large schools of reef fish swimming around rocky coral. That seascape will definitely make you reminisce about scenes of recording life in deep oceans you watched from Marine life TV Shows. Specifically, you could explore one of the largest Cabbage coral populations in Phu Quoc Island in particular, and throughout Viet Nam in general is Phu Quoc Coral Mountain.

🔖 No.3. Phu Quoc U-Turn (富国岛-马蹄形珊瑚礁) details

Phu Quoc U-Turn (富国岛-马蹄形珊瑚礁) which was named as its form from the air, is one of the best well-known names among divers in Phu Quoc Island. It’s because the area is located on one of the remotest and deepest continentals in Phu Quoc. Divers and snorkelers are usually strongly impressed by an abundant coral reef stretching hundreds of meters along the island.
Adequately deep & secluded enough but still within your sight, Phu Quoc U-Turn is one of a handful of coral reefs that has remained unchanged much for years regardless of the rapidly rising number of visitors to Phu Quoc annually.
Due to the difficulty of access to the reef most of the time in a year, it has been managed to avoid numerous amount of harmful effects by unconscious holidaymakers and irresponsible tour operators as well. Massive tour operators particularly have to be accountable for their serious destruction of a vast area of coral reefs in Phu Quoc.

🔖 No.4. Phu Quoc Four Seasons Reef 

The origin of the reef name “Four seasons” arrives from its special location.
As you may know, An Thoi archipelago comprises 16 small islands & an islet within 18 km off the Southernmost town of Phu Quoc. A Thoi Town and most of the reefs in the area can be visited in merely one season: Dry or Rainy season. However, the Four Seasons Reef could be reached in either Dry or Rainy season. It’s because this unique spot is unaffected by both Northeast and Southwest monsoon. Thus the water here is almost kept in a calm state throughout the year, giving snorkelers favorable conditions for safe explorations.
Apparently, Phu Quoc Four Seasons Reef owns a diverse coral reef, notably Table coral and Bushy coral.  Large pieces of Table Coral could be found lying side by side and fully covering the white- sand ground.  Fortunately, the integrity of the reef has stayed sustainable and not destroyed much, thanks to its striving to preserve its beauty from the heavily harmful impacts of unconscious visitors and fishermen who set up their crab-catching nets right on corals, the average depth is 1 – 4 m concealed in the sparkling water.
