Koh Haa islands scuba dive sites in Thailand

A group of five small islands with the main ones named Koh Haa Sam, Koh Haa Yai, and Koh Haa Neung. More than twelve different dives offer you stunning coral gardens filled with macro life and schools of tropical fishes.

Being part of a national marine park makes these islands protected from human activity but only open for seven months per year (from mid-Oct to mid-May). Waters around here are pollutions free and marine life can thrive without commercial fishing and mass tourism. Even shallow areas are full of healthy corals.
This is a great place also for snorkeller and for those only discovering scuba diving – shallow lagoons and great visibility makes diving around the islands spectacular. Underwater pinnacles, limestone stalactites, drop-offs, walls, boulders and other caverns, inter-connected chambers and swim-throughs are filled with critters and small marine animals making the area a great place for underwater photography.
The three main dive sites include the Cathedral, the Chimney, and the Lagoon – the ‘must dive’ spots for any diver with the relevant experience.
Divers can expect to spot porcupine puffer fish, ghost pipefish, octopus, sea snakes, lionfish, nudibranchs, glass shrimps, Hawksbill turtles, Marble and eagle rays, whale sharks, yellow boxfish, butterfly fish, squid, schools of barracuda, sea moths, frogfish and even manta rays.
Koh Haa One is to be considered as the first choice of diving in the area. Marine life here includes zebra sharks, black tip reef sharks, devil and eagle rays, nurse and guitar sharks, and more. It’s also great because of a series of swim-throughs and caverns known as ‘The Chimney’ – it has several shallow entrances, a large, central chamber around 8 – 9m, an exit around 17m, and another shallow exit into the ‘fish bowl’ some parts of The Chimney can get a little narrow in places making it more suitable for divers with advanced certifications.
Koh Haa #2 and #4 also offer excellent scuba diving. On the Koh Haa 4, on the sea-facing side of the island, the reef forms a steep wall. At the foot of the wall is an overhang where divers will find some large rock boulders, covered in soft and hard corals. There are a couple of small caves and plenty of fractures in the limestone where divers may find a rich diversity of macro-life.
In a good day, visibility around the islands can get as good as 50 meters.
The best diving at Koh Haa is between November and Apri as there is a monsoon period from May to October.
