Mosquito Island

written in collaboration with tinoumer (6 spots)


Mosquito Island (also known as Koh Yung) is the remotest island of Phi Phi Islands. It is located approximately 3 miles (5km) off the northern tip of Koh Phi Phi Don. Mosquito Island is made of a narrow rocky cliff about 700 meters long, fringed on its East side by a coral reef.

Mosquito Island is currently closed to all tourist boats by the Department of National Parks until further notice, in an attempt to allow the coral reefs recover from overcrowding.
How to get there?

Mosquito Island is mainly accessible from Ko Phi Phi Don, in approximately 45 to 60 minutes by longtail boat. A snorkeling stop on the reef bordering the island is included in several day tours from Ko Phi Phi. Most excursions include stops at other snorkeling spots, especially Maya Bay, Monkey Beach or Bamboo Island. The half day excursion (including a meal and refreshments) costs on average 1500 baht per person from Ko Phi Phi.

Water entrance

The trip organizer will take you to the reef, and you can enter the water directly from the boat.

Exploration

The area to explore covers the narrow fringing reef bordering the East side of Mosquito Island. The coral reef have been particularly damaged, and you shouldn’t expect vibrant sea beds, even if some coral areas are still quite healthy. Nevertheless, you can still observe a good variety of fish, including some of the finest species of Andaman Sea, as copperband butterflyfish (chelmon rostratus) or Moorish Idol (zanclus cornutus).

You will without doubt come across schools of surgeonfish and parrotfish grazing on the seabed, raising clouds of sediment. In the cavities dug out in the rocks, try to spot an unsuspecting young moray eel. The reef flat is also colonized by dozens of giant clams, making this spot an ideal place to take close-ups pictures of their bright and magnificent mantles.

Restaurant & Accommodation

There are no restaurants and no water supply on the island. Ask your tour guide for details about what is included in the tour, and at least take along a snack and something to drink.
