Diving in Koh Haa Neua
The chimney itself starts at 14m via an opening in the wall of the island, then the narrow shaft rises, nearly vertically to 8m, where it forks, leading to two exit points at 5m. Requiring expert buoyancy skills, this part of the dive is recommended for more experienced divers only.
Inside the chimney you’ll often find clouds of glassfish, and around the site, a great diversity of marine life can be found. As well as the coral reef and dancing anemones, there are critters and cowries, lionfish and frogfish, banded seasnakes and morays, and schools of barracuda and snapper to name but a few. Take it slowly for a chance to spot the tigertail seahorses which havebeen reported here too.

Diving in Koh Haa Yai
Koh Haa Yai offers wall diving down a sandy bottom at 30m on its south side, and spectacular caves and swim-throughs on the south-east corner. Travelling west to east, the entrance of the first cave lies at 14m. This smaller cave has a sandy floor and gets narrower as you go inside, so cave diving experience and certification is essential here. Moving further east you’ll find a much larger, less complex cavern, from which this dive site takes its name.
Also at a depth of 14m, ‘The Cathedral’ is one large cavern, split into two main chambers by a vertical wall, and connected by a swim-through. The ceiling reaches 2 - 3m above sea level, so as the light floods in from the surface, the chambers are illuminated with an amazing blue glow, providing an unforgettable diving experience and an excellent photo opportunity.
Koh Haa Yai experiences mild to moderate currents running east - west or vice versa, and as well its caves, there is plenty to see. There are soft corals scattered along the walls, hard coral structures outside the entrance to the caves sloping away to 25+m, a wealth of macro life hiding in the cracks, schools of the usual colourful reef fishes, and even the occasional hawksbill turtle.
