Ko Haa Yai is the biggest of the five islands that make up Ko Haa and is one of the most spectacular. It is most famous for the enormous cathedral caves - two huge underwater caverns that it is possible to surface in & swim between - that are always a delight for visiting divers. It is also an excellent spot to see Hawksbill Turtles feasting on Bubble Coral and has a series of stunning underwater pinnacles carpeted in soft corals and a myriad of marine life from shrimps & crabs to Giant Morays, Trumpetfish, Flutemouths & many more colourful reef species.
