A remote haven ringed with verdant coral reefs, Mosquito Island or Koh Yung is the northeasternmost island of the Phi Phi archipelago. Also known as Moskito Island, it has two beautiful beaches. You can visit here for a swim, relax by the beach with a book, or even head south of the island for snorkeling and diving. The best way to get here is by Longtail boat.
Hire a long-tail boat from Tonsai Pier or Laem Tong, which you can hire for the day for THB 2,000. From a certain direction, the island’s bent nail-like shape resembles a mosquito, and the ocean here is the only source of staghorn corals in the Andaman Sea. Largely unspoiled for tourists, Mosquito Island is excellent for hiking limestone cliffs, sunbathing, and diving.
