Phu Quoc is Vietnam's largest island, set in the warm waters of the Gulf of Thailand, it has transformed from a remote fishing destination into one of Southeast Asia's most celebrated tropical island resorts, while retaining the natural beauty and unhurried character that made it worth visiting in the first place. Over half the island is protected national park — a dense jungle of hardwoods and pepper plantations that gives the interior a wildness entirely at odds with the resort infrastructure of the western coast. The beaches, particularly the Long Beach (Bai Truong) strip and the secluded Ong Lang and Bai Sao, rank among the finest in Vietnam, their waters extraordinarily clear and warm year-round. Sunset Town in the south combines a bustling night market, the dramatic Kiss Bridge, and the Sun World Hon Thom cable car — the world's longest cable car over water — linking the mainland to Hon Thom Island. And the fish sauce factories, pepper farms, and Phu Quoc Prison Museum give the island a cultural and historical depth that extends well beyond its considerable beauty.
