Pronounced “ko pee pee” is the popular name used for Phi Phi Don, the largest & only inhabited island in the group of 6 which bear its name. The islands became part of a protected National Maritime Park in 1983 thus ensuring that the fragile balance of the regional ecological systems are kept in check. Widely recognized as being one of the most naturally beautiful islands in the world, this southern Thai paradise lies some 50 kilometers south-east of Phuket in the Andaman Sea, with the only access to the islands being by a two hour boat journey. The islands came to worldwide prominence when Ko Phi Phi Leh was used as a location for the 2000 British-American film The Beach. This attracted criticism, with claims that the film company had damaged the island's environment, an accusation the film's makers contest. The film's release was attributed to an increase in tourism to the islands. Phi Phi Leh also houses the 'Viking Cave', from which there is a thriving bird's nest soup industry. Ko Phi Phi was devastated by the Indian Ocean Tsunami of December 2004, when nearly all of the island's infrastructure was destroyed. As of 2010 most, but not all, of this has been restored.
