Koh Haa Lagoon is formed by Koh Haa # 2, Koh Haa # 3 and Koh Haa # 4. It is a stunning, turquoise blue lagoon that is beautiful above and below water. It is impossible not be impressed when the dive boat pulls into the lagoon surrounded by limestone walls rising sheer from the ocean floor.

The boats usually moor in the Lagoon, a large sandy area around 5-6 meters deep. It is punctuated by hard coral bommies, home to some very large giant morays also be prepared to be pestered by our friendly and curious porcupine fish and a good place for finding sea moths, flounders and the occasional Walkman.

Koh Haa # 3 has a white sand beach which sits below cliffs covered in vegetation. A shallow crystal clear lagoon connects to the smaller islets of Koh Haa # 2 and # 4 which are actually little more than limestone pillars.

It is possible to navigate from the lagoon around both Koh Haa # 2 & Koh Haa # 4 and then back to the boat or just take your time around one of the islands looking for little critters. 

Depths around the back of # 2 and # 4 can reach 30 plus meters, garden eels hang out at 30 meters, large schools of yellow snapper swirl around their base and glass fish blanket the walls. A sandy slope separates the two islands and a school of juvenile barracuda patrol lazily back and forth. Hawksbill turtles regularly come to munch on the bubble coral,

Other highlights of these dive sites

include ornate ghost pipe fish, frog fish, mantis shrimp, Harlequin Shrimp, scorpion fish, lion fish and clown fish can be found everywhere.

On the west side of Koh Haa # 3 a steep slope dominated by plate corals drops to a depth of around 18 meters, at each end of the site the slope becomes a wall and large pinnacles covered in soft corals and glass fish, jut out from the sandy ocean floor.  

A favourite with divers and snorkellers alike the lagoon has something for everyone. A white sandy beach for sun worshippers and shallow clear water for snorkellers. Newer divers can hone their skills in the shallower waters of the lagoon while more experienced divers can enjoy the beautiful soft corals on the outer pinnacles which fall away to over thirty metres.
