Phu Quoc - Turtle Island

Phu Quoc diving accommodates shallow diving , between 10-12m at best.  Due to the breezy weather conditions we dived in the north of the island which is more sheltered than the greater range of dive sites offered in the south.  When there is more wind the southern islands are more exposed and conditions can change drastically.  Diving there is more suited to advanced divers.  Amongst the divers on our groups were visitors trying scuba diving for the first time so we were unable to head south.

Diving in Phu Quoc will be appreciated more by divers interested in macro and muck diving, you won't see big sharks, turtles or rays (even though our first dive site was called turtle island!).

We saw lots of damselfish, angelfish, anemone fish, nudibranchs (jorunna funebris) puffer fish, hard coral, whip coral and giant barrel sponge.

Depth: 6.7m
Temperature: 27 degrees C
Time: 40min 
Visibility: 10m

Hard Coral, Nha Trang - Hon Mun Island, Vietnam


Hard corals are the reef builders. The hard coral polyp, such as those in Brain Coral, secrete a limestone skeleton cup around itself and live inside it for protection. When a polyp dies, its skeleton house remains intact.  The name "hard coral" derives from the skeleton which forms around the polyp.
