The full name for the national park is Hat Nopparat Thara - Mu Koh Phi Phi National Park which, besides being quite a mouthful, is located in Krabi Province, not Phuket Province as many people think. It's the 46th national park of Thailand and covers 387.90 km². The park stretches from the Thai mainland at Nopparat Thara Beach in Krabi, to the islands of Phi Phi, which are easy to reach by regular ferry from both Phuket and Krabi.
