The Phi Phi Islands (Thai: หมู่เกาะพีพี, Thai pronunciation: [pʰīː pʰīː]) are located in Thailand, between the large island of Phuket and the western Strait of Malacca coast of the mainland. The islands are administratively part of Krabi province. Ko Phi Phi Don ("ko" (Thai: เกาะ) meaning "island" in the Thai language) 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 (or "Ko Phi Phi Leh"), are visited by many people as well. The rest of the islands in the group, including Bida Nok, Bida Noi, and Bamboo Island (Ko Mai Phai), are not much more than large limestone rocks jutting out of the sea.
Phi Phi Don was initially populated by Muslim fishermen during the late 1940s, and later became a coconut plantation. The Thai population of Phi Phi Don remains more than 80% Muslim. The actual population however, if counting laborers, especially from the north-east, from the mainland is much more Buddhist these days. The population is between 2,000 to 3,000 people (2013).
