The Phi Phi Islands Are located about 45 Km southeast from Phuket, 42 km south of Krabi Town. They can be reached in between 1.5 - 2 hours depending on the type of boat you choose. Boats leave from Phuket, Krabi.

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.

Later the p was pronounced with a stronger aspiration and the name became the Phi Phi (Pee Pee) we know today. The name originally referred to the mangrove wood found there.

There are 6 islands in the Phi Phi group; Phi Phi Don, Phi Phi Ley, Bida Nok, Bida Nai, Koh Yung, and Bamboo island ; 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.

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.

Phi Phi Ley Island is 6.6 square kilometers in total area: 3 km in length and 1 km at its broadest point. The island is entirely limestone and steep cliffs rising from the sea very nearly ring it. surrounding waters average about 20 meters in depth, reaching 34 meters at the deepest point off the island's southern tip. Phi Phi Ley has several beautiful bays: Piley, Maya, and Loh Samah. Maya Bay is one of Phi Phi's number one tourist attractions, being that is was the setting for the film "The Beach" starring Leo DiCaprio.

On Phi Phi Ley's northeast is the famous Viking Cave. It is a place much revered by the local people who still come there to collect the swift's nests used to make Bird' nest Soup, a Chinese delicacy.

On the eastern and southern walls of the cave are coloured drawings dating from historic times. There are pictures of elephants and also of various boats : European, Arab, and Chinese sailing ships; barques, motorboats and steamships. It is theorized that these were drawn by pirates who paused in their travels from west to east, sheltering in the cave to escape the monsoon winds, transfer cargo, or make repairs.
