Koh Haa Lagoon lies embedded in between 3 islands, #2, #3 and #4. This dive site is the perfect place for divers of all comfort and certification levels to dive. The Lagoon is the ideal place to learn and practice your buoyancy or navigation skills, then lead dives towards the 2nd and 4th islands and their beautiful slopes and walls. The lagoon itself is a plateau which begins from a small beach and extends to the edges in 3 directions, opening up to the open ocean and deeper depths.

Koh Haa 2 offers a variety of features. On the lagoon side the dive is shallow and you can often spot a large school of barracuda there. Depending if you choose to dive “right or left shoulder”, your dive will eventually lead to the outer slopes and walls of #2. Around this islands shallows you can find dragon sea moths, large brown marbled groupers, turtles and even those difficult-to-spot stonefish. The island is punctured through by a shallow swim-through, which is accessible on higher tides. Ask your instructor/divemaster more about diving through, as a safety-stop will be required before entering this swim-through at the end of the dive.

Koh Haa 4 is very similar to Koh Haa 2 in topography with a few exceptions. You might want to lead this dive by jumping in the lagoon and choosing to go “left shoulder”. As you are going around the rock formations towards the outside of the island, you will come across a shallow swim-through, which rises to about 3-4 meters, which is why attempting this swim-through, you should start your dive here or make sure you make your safety stop before going for this swim-through as a safety-stop will be required before entering at the end of the dive here as well.

After this you can choose to stay shallower, saving both air and bottom time before descending down to a beautiful outer reef at about 32 meters. Before descending further, look out into the blue to your right to catch that beautiful school of giant batfish often lingering along in the blue. The deep reef itself is riddled with corals, both hard and soft, schools of snapper hunted upon by trevallies and emperors, also large giant moray eels and the occasional larger ray are often tucked away under the rocks and corals.

For friends of shallower dives, the walls of #4 are riddled with macro life as well. Many species of nudibranch and also pipefish and tiger cowries live in the small nooks and crannies of the walls.

A few smaller reefs in between #2 and #4 host massive amounts of glass fish and different types of crab and shrimp. This in turn attracts other creatures such as ornate ghostpipefish and other predatory fish as well, such as the battle-ship-like lionfish. Before peering under the corals, make sure you know what lurks in the midst of all those glass fish before going further.
