Mosquito Island (also known as Koh Yung) is the remotest of the Phi Phi Islands. It is located approximately 3 miles/5km off the northern tip of Koh Phi Phi Don. It has on its East side a narrow rocky cliff about 700 meters long, fringed by a coral reef, which can be snorkeled during boat tours.
Mosquito Island is temporarily closed to all tourist boats by the Department of National Parks, with no official date for reopening. Please check the last updates before traveling.
Mosquito Island is mainly reached 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 most day or half-day tours sold in Ko Phi Phi. Most tours include stops on several snorkeling spots, including Maya Bay, Monkey Beach or Bamboo Island.
Water entrance is directly from the boat.
The snorkeling area covers the narrow fringing reef bordering the East side of Mosquito Island. The coral reef is badly damaged, and you shouldn’t expect vibrant seabed, even if some coral areas are still quite healthy.
Nevertheless, you can still spot a good variety of fish in the area, including some of the finest species of Andaman Sea, such as the copperband butterflyfish and the Moorish Idol.
This spot is popular with schools of surgeonfish and parrotfish grazing on the seabed, raising clouds of sand. In the cracks of the reef, you may also spot moray eels. The reef flat is also home to dozens of giant clams, making Mosquito Island a great location to take photos of their fluorescent mantles.
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 with you some snacks and drinks.
These snorkeling spots are accessible to beginners and kids. You will enter the water gradually from a beach, or in a less than 3ft. deep area. The sea is generally calm, shallow, with almost no waves or currents. These spots are usually located in marked and/or monitored swimming areas. It is not necessary to swim long distances to discover the sea life.
This level only apply when the spot experiences optimal sea and/or weather conditions. It is not applicable if the sea and/or weather conditions deteriorate, in particular in the presence of rough sea, rain, strong wind, unusual current, large tides, waves and/or swell. You can find more details about the definition of our snorkeling levels on our snorkeling safety page.

Snorkeling spots are part of a wild environment and their aspect can be significantly altered by weather, seasons, sea conditions, human impact and climate events (storms, hurricanes, seawater-warming episodes…). The consequences can be an alteration of the seabed (coral bleaching, coral destruction, and invasive seagrass), a poor underwater visibility, or a decrease of the sea life present in the area. Snorkeling Report makes every effort to ensure that all the information displayed on this website is accurate and up-to-date, but no guarantee is given that the underwater visibility and seabed aspect will be exactly as described on this page the day you will snorkel the spot. If you recently snorkeled this area and noticed some changes compared to the information contained on this page, please contact us.

Remember that all marine activities, including snorkeling, are potentially dangerous, and that you enter the water at your own risk. You must take an individual weather, sea conditions and hazards assessment before entering the water. If snorkeling conditions are degraded, postpone your snorkeling or select an alternate site.
