Maya bay. Phi Phi (also known as Koh Phi Phi, Thai: หมู่ เกาะ พี พี) is a small archipelago located in the Andaman Sea, south of Thailand. It has become in recent years a very popular place for tourism, to the point that the expansion of hotel infrastructures are growing uncontrollably to accommodate so much tourism demand. The Phi Phi Islands (Thai: หมู่ เกาะ พี พี, rtgs: Mu Ko Phiphi, pronounced [mːː kɔʔ pʰīː.pʰīː]) 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 ("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.
