One of the best beach resort of Vietnam is Phu Quoc Island, which covers an area of 567sq.km (about 62km long and between 3km and 28km wide), and its population is approximately 85,000 (in 2001).

Phu Quoc is called the island of "99 mountains" because of its many sandstone chains gradually descending from the north to the south. The longest one is Ham Ninh which stretches for 30 km along the eastern edge with its highest peak called Mt. Chua (603m).

Phu Quoc has a monsoon sub-equatorial climate. There are two seasons in the year: the rainy season (October only) and the dry season (November to September). The average annual rainfall is 2,879 m and the average temperature is 27oC. Trips to Phu Quoc can be made all year round, but the best time is dry season when the sky is always sunny, clear and blue.

Phu Quoc is also called the Emerald Island because of its natural treasures and infinite tourism potential. The island is well known for its high-quality fish sauce; Phu Quoc fish sauce smells particularly good since it is made from a small fish, ca com, with a high level of protein. The island produces 6 million liters of fish sauce every year.
