Phi Phi Islands

The Phi Phi Islands are among Thailand's most iconic dive destinations, a stunning archipelago in the Andaman Sea where towering limestone cliffs plunge into crystal-clear waters teeming with tropical marine life. With depths reaching thirty meters across multiple dive sites and conditions ranging from sheltered bays to current-swept pinnacles, the Phi Phi archipelago offers advanced diving experiences that match the dramatic beauty of the above-water scenery. The archipelago comprises six islands, with Phi Phi Don serving as the inhabited base for dive operations and Phi Phi Leh providing the dramatic backdrop of Maya Bay fame. The underwater landscape mirrors the limestone karst topography above, with walls, caves, and overhangs carved into the rock by millennia of ocean action. These geological features create habitat complexity that supports extraordinary marine biodiversity. Dive sites around the islands span the full spectrum of difficulty and character. The Bida Islands at the southern tip offer wall diving and reliable shark encounters, while the more sheltered bays on Phi Phi Don provide gentle reef diving suitable for all levels. The deeper sites reach thirty meters along dramatic walls where the limestone drops into the Andaman blue, and the current-exposed positions attract pelagic species that add excitement to every dive. Marine life at Phi Phi is exceptional. Leopard sharks and blacktip reef sharks are encountered regularly, while whale sharks make seasonal appearances. Hawksbill turtles feed on the healthy sponge communities, and the reef fish population is dense and diverse. The macro life is equally impressive, with ghost pipefish, seahorses, frogfish, and dozens of nudibranch species rewarding photographers who look closely. The combination of stunning limestone scenery, world-class underwater encounters, and the infrastructure of a well-established dive destination makes the Phi Phi Islands essential diving for anyone visiting Thailand's Andaman coast. Whether accessed as a day trip from Phuket or Krabi, or explored from a base on Phi Phi Don, the archipelago delivers some of the most complete and memorable diving experiences in Southeast Asia.
