What is Koh Hong?

Koh Hong is a limestone island at the edge of Phang Nga Bay, about 17 km in a straight line northwest of Ao Nang. It's part of the Than Bok Khorani marine national park, with islands, caves and tropical forest.

The highlight is an enclosed emerald lagoon. Sheer cliffs ring it almost completely, and a narrow channel leads in from the sea. In Thai such lagoons are called 'hong' — 'room'. Outside, the island has a white-sand beach under trees and clear water for snorkelling.

How the island works

Boats land on the beach on the outer side of the island. You enter the lagoon by longtail or kayak through a narrow channel; it isn't always possible — it depends on the water level. Inside it's quiet and shady, with trees and shrubs on the walls.

The island has toilets and a picnic area; there are no hotels and no overnight stays. Lots of tours arrive by day, so the calmest time is early morning. Some tours add a climb to a viewpoint and neighbouring islands.

What to see and do

  • The emerald lagoon inside the island.
  • Kayaking in the lagoon and along the cliffs.
  • The white-sand beach under the trees.
  • Snorkelling by the rocks near the beach.
  • Neighbouring islands Lao Lading, Pakbia and Daeng on the tour.
  • Views of Phang Nga Bay and its dozens of islands.

How long do you need?

Koh Hong takes 4–5 hours including the boat, and a full tour with the neighbouring islands takes most of a day. Tours usually leave in the morning and return by 15:00–16:00.

To catch the lagoon without the crowds, choose an early tour — boats leave around 7:00.

Is Koh Hong worth visiting?

Yes: an enclosed lagoon among cliffs and a white beach make it one of the most beautiful trips from Krabi, and calmer than Phi Phi.

The YesGo take: the park fee comes on top of the tour price, and the lagoon isn't accessible at every water level. Go in season, early, and ask the operator whether the boat enters the lagoon.

How to do it right

  • Bring spare cash for the park fee.
  • Keep your phone in a dry bag.
  • Ask whether the tour includes kayaking.

How we checkedThere's no official website or Wikipedia article on the island. The park and its area are from Wikipedia. Park fee: most often 300 baht for foreign adults and 150 for children (100 in one source), 400 in charter listings; we give 300 and mark it unconfirmed. The ≈ 17 km distance is a straight line from Ao Nang Beach to the Wikidata coordinates; the sea route is longer. Lagoon access depends on the water, so we give no fixed times. We don't describe the viewpoint: sources say little about it.
