Mosquito Island is Phi Phi Islandís remotest. Mosquito Island is a limestone cliff rock about 700 meters long. It has 2 small beaches that are covered in Mosquitoes at sunset and hence gives it itís name.
There are some mooring buoys off the south eastern shoreline where longtail boats can tie up for snorkeling but even still this is one of Phi Phiís quietest beach locations . There is an abundance of soft corals here, formed due to the strong tides that sweep down past the island every day from the Andaman Sea and Phang Nga Bay.
Diving on Mosquito Island is mainly confined to the north eastern tip where there is a 3 headed pinnacle at 9-14 meters below low tide. Here there are schools of juveniles that swarm over the rocks that make diving here a great pleasure. Black tip sharks can be seen regularly in the northern cove.
