Things to Do
The hidden lagoon is what makes Koh Hong different from every other island in the area. Most people don't know it's there until they're standing inside it. And when they are, they tend to go very quiet.

The lagoon sits in the centre of Koh Hong, enclosed by a ring of limestone cliff. The only way in is through a narrow gap in the rock, either swimming or kayaking, depending on the tide. Once you're through, you're in a completely enclosed bay, open only to the sky above.
The water inside is typically calmer than outside, the colour shifts between deep green and turquoise depending on the light, and the acoustic effect of the walls means you can hear your own echo. It's one of those places that photographs don't quite do justice to.
Access through the gap requires mid-tide or lower. At high tide, the entry becomes too narrow to swim through safely. All our tours are timed around the tidal window, your guide will confirm on the day. See our Koh Hong tides guide for more detail.
