In the early 17th century, Phu Quoc was a desolate area, where Vietnamese and Chinese immigrants earned their living from sea cucumbers. From 1782 to 1786, Phu Quoc became a stronghold of Lord Nguyen Anh, later Empe 
ror Gia Long, in his confrontation with Tay Son forces.
In 1869, the French occupied it and set up rubber and coconut plantations in the island. From 1967 to 1972, a P.O.W detention camp of 40,000 inmates during the war covering on 400 hectares was built at An Thoi by the Saigon regime.
After being liberated on 30 April 1975, Phu Quoc has been converted into an ideal tourist destination for nature and sea lovers.
Located in the Gulf of Thailand, the hear-shaped island lies just 62 nautical miles from Rach Gia and nearly 290 nautical miles from Laem Chabang (Thailand). It covers an area of 567 sq. km (about 62 km long and 3-28 km wide) and is situated at 10001′-10027′ north latitude and 103051′-104050′ east longitude. Its population is approx. 85,000 (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 270C. 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.
