This island is also known as Koh Gai, Koh Kai and Koh Hua Khwan. Chicken Island has similar dimensions and is also a rock island. The comical name is acquired because of a kind of rock in the south of the island, whose shape resembles the outline of the chicken.
The coastline is rocky but has several beautiful reefs at the west of the island which are great for snorkeling.
During low tide, Chicken Island can be reached from neighbouring islands Koh Mor and Koh Tub on the sand spit Talay Waek.
