- About Phu Quoc Island:

Phú Quốc is the largest island in Vietnam. Phú Quốc and nearby islands, along with distant Thổ Chu Islands, is part of Kiên Giang Province as Phú Quốc District, the district has a total area of 574 square kilometres (222 sq mi) and a permanent population of approximately 103,000.[1] Located in the Gulf of Thailand, the district of Phú Quốc includes the island proper and 21 smaller islets. The district seat, Dương Đông, is located on the west coast, and is also the largest town on the island. The economy is centered on fishing, agriculture and a fast-growing tourism sector.

From March 2014, Vietnam allows all foreign tourists to visit Phú Quốc visa-free for a period of up to 30 days.

Phú Quốc lies south of the Cambodian coast, west of Kampot, and 40 km west of Ha Tien, the nearest coastal town in Vietnam. Roughly triangular in shape the island is 50 kilometres (31 mi) long from north to south and 25 kilometres (16 mi) from east to west in the north at its widest. It is also located 62 nautical miles (115 km; 71 mi) from Rạch Giá and nearly 290 nautical miles (540 km; 330 mi) from Laem ChabangThailand.

A mountainous ridge known as "99 Peaks" runs the length of Phú Quốc, with Chúa Mountain being the tallest at 603 metres (1,978 ft).

Phu Quoc Island is mainly composed of sedimentary rocks from the Mesozoic and Cenozoic age, including heterogeneous conglomerate composition, layering thick, quartz pebbles, silica, limestone, riolit and felsit. The Mesozoic rocks are classified in Phu Quoc Formation (K pq). The Cenozoic sediments are classified in formations of Long Toan (middle - upper Pleistocene), Long My, (upper Pleistocene), Hau Giang (lower - middle Holocene), upper Holocene sediments, and undivided Quaternary.

Phu Quoc is famous for its two traditional products: fish sauce and black pepper. The rich fishing grounds offshore provides the anchovy catch from which the prized sauce is made. Pepper cultivation is located inland in the center of the island. More recently a pearl farm was established.

Tourism plays an important role in the economy with the beaches being the main attraction. Phu Quoc was served by Phu Quoc Airport with air links to Ho Chi Minh City (SaigonTan Son Nhat International AirportHa noi (Noi Bai International Airport), Rach Gia (Rach Gia Airport), Can Tho (Can Tho International Airport). Phu Quoc Airport was closed and replaced by the new Phu Quoc International Airport from December 2, 2012. Phu Quoc is also linked with Rach Gia and Hà Tiên by fast ferry hydrofoils.

Air Mekong has its headquarters in An Thoi, Phú Quốc.

With the opening of the new Vinmec Phu Quoc International Hospital in June 2015, Phu Quoc will add an additional source of revenue to the local economy in terms of medical services, medical tourism, and medical education.

The island's monsoonal sub-equatorial climate is characterized by distinct rainy (June to November) and dry seasons (December to May). The annual rainfall is high, averaging 2,879 millimetres (9.446 ft). In the northern mountains up to 4,000 millimetres (13 ft) has been recorded. April and May are the hottest months, with temperature reaching 35 °C (95 °F).
