Ko Ngai (เกาะไหง) is an island district in Krabi Province, but actually it can better be reached via Trang in the Southern Andaman Coast. Like many other coastal destinations in southern Thailand, it is known for its diving and long white beaches.
Ko Ngai (Hai) is a tiny island measuring 4 km long and 2 km wide. Mountainous and covered by tropical forest, much of the coastline is indented with rocky headlands, while the eastern part has some beautiful sand beaches, and in the south coconut plantations and more beautiful smaller beaches. The island has a white beach and clear water and is surrounded by magnificent corals.
Don't be surprised to see crab-eating monkeys and monitor lizards coming down from the mountains. In the uninhabited western and northern parts of the island, bird watchers should have a field day looking out for migrating birds. Snorkelling is easy along the western and southern coast, where some reefs can be accessed directly from the beach.
