Koh Haa

Koh Haa (5 islands in Thai) is a group of five small islands just 25 km west from Koh Lanta. Liveaboards from Phuket normally dive Hin Daeng, Hin Muang and Phi Phi as well as Koh Haa.

The main draw at Koh Haa Yai is “the Cathedral,” a large underwater air chamber that divers can surface up in to. There are two entrances and lots of natural light inside making it safe to dive in. From within you can look up at the amazing stalactite formations hanging down from above. There are also smaller caves leading off from the main chamber, which should only be dived by tek divers, and other interconnected swim-thru’s.

Koh Haa seems to become a better dive site every year, may be the national park rangers are keeping the fishing boats away. Soft coral coverage is excellent. All the usual reef fish are around, plus plenty of critters. Whale sharks, manta rays and eagle rays are spotted on occasion. Leopard sharks are pretty common at Koh Haa and hawksbill turtles are also seen.

There is deep water separating the islands where currents can be strong, but there are also sheltered bays so anyone can dive Koh Haa.

Visibility is average, 5-20m. Maximum depth is 30 metres.

Koh Haa is excellent for snorkelers too, the shallow hard coral reefs are pristine.
