The Hong, (Thai for room) gives Koh Hong its name. Sheer ‘walls’ enclose a stunningly beautiful, enclosed pool with a large chimney opening to the sky. Once inside, you will find perfect opportunities for photography, relaxing or exploring.
Entering from the east, spot the dog rock formation on the top of the cliff. Park rangers have recently surrounded the island with a buoyed rope. The authorities forbid dinghies to enter the main cave.

The best anchorage in this island group of (A) lies between Koh Hong and the shallow water to the west of Koh Na Khae. Suitable for both seasons, this very picturesque anchorage has good holding in approximately 12 metres on a muddy bottom. It gives easy access to explore around Koh Hong by dinghy.
Just south of the island (B) is another option in 4-5 metres on a muddy bottom. It is directly outside the small cave that opens into the lagoon. Both these anchorages are very busy with day trips and sea canoe tours coming and going during the day.
If swimming in these channels beware of strong currents, particularly during spring tides. There is a National Park station on Koh Yai. It is likely the ranger will approach and ask for the park entry fee, currently 400 baht per person.
Take care, if heading north from this location, to keep well clear of the shallow bank to the west of Koh Na Khae. We don’t recommend the passage between Koh Yai and Koh Na Khae for any but shoal draft vessels. Yachts proceeding east from this group should pass north around Koh Na Khae or south of Koh Yai.
