The Phi Phi Islands are a Thai island group located between the big island of Phuket and the Thai coast of the Malacca Strait. The islands are administratively part of Krabi Province. The largest and most inhabited island in the group is Ko Phi Phi Don, however the beaches of the second largest island, Ko Phi Phi Le, are also popular. The rest of the group’s islands, including Bida Nok, Bida Nai, and Bamboo Island, are nothing more than enormous limestone boulders protruding from the water. The islands are usually reached by speedboats or long-tail boats from Krabi town or docks in Phuket Province. The beaches and clean water on the islands are beautiful, and the natural environment is protected by national park status. Since the premiere of the film The Beach, tourism on the islands has skyrocketed.
