Koh Haa Chimney – Koh Haa 1 Neung

The entrance of Koh Haa Chimney

lies at 18 meters and opens up into a small chamber absolutely full of bronze cave sweepers, the exit hole above is at 5 meters. Therefore if you have exceptional buoyancy control you can enter another very narrow tunnel. It links up with a small cave, from the cave you can swim directly onto the reef again. From inside the cave looking out across the reef and anemone garden, watching the passing fish is a magical experience.

To the south of Koh Haa Chimney
