The Phi Phi Islands (Thai: หมู่เกาะพีพี, Thai pronunciation: [pʰīː pʰīː]) are 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 ("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. The Islands are reachable by speedboats or Long-tail boats most often from Krabi Town or from various piers in Phuket Province.
