Phi Phi Islands are an island group in Thailand, between the large island of Phuket and the west Strait of Malacca coast of the mainland. The islands are administratively part of Krabi province. Ko Phi Phi Don is the largest island of the group, and is the most populated island of the group, although the beaches of the second largest island, Ko Phi Phi Lee, are visited by many people as well. The rest of the islands in the group, including Bida Nok, Bida Noi, and Bamboo Island, are not much more than large limestone rocks jutting out of the sea. The Islands are reachable by speedboats or Long-tail boats most often from Krabi Town or from various piers in Phuket Province. Phi Phi Don was initially populated by Muslim fishermen during the late-1940 and later became a coconut plantation. The islands came to worldwide prominence when Ko Phi Phi Leh was used as a location for the 2000 British-American film The Beach.
