The Phi Phi islands are located about 45 Km southeast from Phuket, 42 km south of Krabi Town and 40 km from Ao Nang Beach. They can be reached in between 1 to 3 hours depending on the type of boat you choose. Boats leave from Phuket, Ao Nang and the Chao Fa Pier in Krabi Town on a daily basis.

The name "Phi Phi" is derived from Malay, and the original was Pulao Pi ah Pi, where in pulao is the Malay word for island , and Pi, pronounced with a soft "p" sound, was very close in pronunciation to the English word "bee"; the ah was dropped, so the name was said something like Bee Bee.

There are 6 islands in the Phi Phi group; Phi Phi Don, Phi Phi Ley, Bida Nok, Bida Nai, Koh Yung, and Koh Phai; total land area is 42 square kilometers. The islands were declared a National Park in 1983, and development is limited to Koh Phi Phi Don only. All other islands are uninhabited.

Yung Island lies to the north of Phi Phi Don. there is a rocky beach on the east side, and a smaller strand of sand in a fold of the hill. Many beautiful and various corals are found there. Good for shallow snorkeling.

Phi Phi Don Island covers a total area of 28 square kilometers: 8 km in length and 3.5 km at its broadest point. At the north end is Cape Laem Tohng, where there is a Chao Ley, or sea gipsy village. These sea gipsies emigrated from Koh Lipeh in Tarutao National Park, near the border with Malaysia and lived on the islands long before tourism arrived. There are two long beaches next to the main town - the two curving bays of Ton Sai and Loh Dalam. The town was hit hard by the tsunami on December 26th 2004, and rebuilding is still in progress in many areas.
