Phu Quoc Half-moon reef is a fringing coral reef with the water area of hundred thousand square meters. The surroundings rocks cover the water of Half-moon reef and protect it from North-east moonson thereby the best time to visit is from October to May when the water becomes calm not choppy, but sometimes in the summer (May till October) or rainy season the sea is calm.

Phu Quoc Half-moon Reef’s calm lee water (in the Dry Season) is quite large as we usually take at least 1 – 1.5 hours to explore the reef in-depth and even longer if you would like to spend time for free-snorkeling. The underwater terrain is rocky with different depths, we find here coral-covered canyons, coral-covered cliffs, the ground of anemone at the depth of 4m – 7m, or big helmet-shaped honeycomb corals.
