What Is Koh Hong

Koh Hong, also known as Ko Hong, is a small island located in the Andaman Sea off the coast of Ao Nang in Krabi Province, Thailand. It is part of the Than Bok Khorani National Park and is one of the most popular islands in the Hong Archipelago.
The island is famous for its stunning crescent-shaped beach and a hidden inner lagoon that can only be accessed through a narrow opening in the limestone cliffs. The word “Hong” in Thai means “room” or “chamber,” describing the enclosed lagoon surrounded by steep rock walls.

Why the Crescent Shape Makes It Unique

Koh Hong’s crescent-shaped beach is what makes it stand out among other islands in southern Thailand. The curve of the beach forms a natural bay protected on both sides by tall cliffs. This shape creates calm, crystal-clear waters ideal for swimming, kayaking, and snorkeling.
Behind the beach lies the hidden lagoon, often called the “Inland Sea.” It is accessible only by kayak or boat at certain tide levels. The contrast between the open beach and the enclosed lagoon gives Koh Hong a special charm that attracts nature lovers, photographers, and adventure seekers alike.
The combination of white sand, emerald water, and dramatic limestone cliffs makes it one of the most picturesque destinations in the Andaman Sea.
