Koh Haa Chimney is the most northerly of the island group and famous for the tunnel system on the southwest corner.

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

of Koh Haa chimney site entrance at a depth between 20 and 30 meters we find large limestone rock pinnacles that create a playground of channels and swim throughs. Huge pink and purple soft corals are also growing out of the sand everywhere. The west and northeast of the island have stunning drop off walls to 35 meters.

This dive site is in pristine condition, and the normally clear water make for beautiful dive. Look out for the big stuff in the blue, and rare critters among the corals like Harlequin Shrimps, Ghost Pipefish and more.
