Ko Poda Nok (GPS: 7.9539, 98.80686) is an island in the sea in Krabi Province, Thailand. It is often nicknamed Ko Kai, which means Chicken Island, and is variously spelled as Koh Gai and Koh Khai. The island is also called Koh Hua Khawan. It was given this nickname because of the rock formation at one side of the island, which has the appearance of a chicken.
Ko Poda Nok consists of steep cliffs on one end, and beautiful beaches along a peninsula on the other. At high tide, this peninsula gets flooded, creating a small island. There is no accommodation on Ko Poda Nok. However it offers excellent snorkeling opportunities in its warm and clear water which is rich in coral. As it is not affected by the monsoon, it can be visited all year round.
Ko Poda Nok is south of Ko Poda, and is the largest in a cluster of islets. Surrounding it include Ko Tap in the north, Ko Khom in the southeast, Ko Ya Wa Bon in the southwest, Ko Ya Wa Bong Ko and Ko Urai in the west.
