Koh Phi Phi (pronounced Pee Pee) is located about 45km East of Phuket and offers some excellent dive sites for all levels of diver. Phi Phi Islands diving day trips are available from Phuket by speedboat or slower dive boats. Phi Phi special. In many places you find shallow hard coral gardens, making Phi Phi a good spot for snorkeling as well as scuba diving. Koh Bida Nok and Koh Bida Nai, at the South end of the Phi Phi island chain are among the best sites in the region.
