Located in the middle of Koh Haa group, the Lagoon is a 5-m deep area surrounded by a pair of small limestone towers (Koh Haa No.2 and No.4) to the east, and Koh Haa No.3 to the west. The most famous spot of this divesite is located to the east of the lagoon, the limestone towers. The south tower covered with colourful soft coral, huge sea fans, black corals, fields of anemones and orange cup coral forms the south side of the islands, with the outer sand bottom at a depth of around 24 m. A number of rocks are scattered beyond the wall, where divers may find snappers, and you will find hard coral scattered all around the sandy, sloped area connecting the two islands. The north tower is quite similar to the south, except things are on a larger scale! Koh Haa No.3, a long island to the west of the lagoon, is also another good dive spot, however, less famous than the two towers. Current Mild to moderate running from north to south and vice versa. There is usually little or no current at the middle of the bay. This site is perfect for macro lovers. Because of the nature of lime-stone cliffs, there are many cracks and crevices along the wall, offering shelter to many small creatures like shrimp and crabs. Take a closer look at a sea fan, and you may find ornate ghost pipefish and cowries camouflaged among the fronds. Harlequin Shrimp and sea moth have been spotted between the two islands sometimes. Many species of nudibranch make their home at the wall and lobsters and squid can also be found here. During a night dive, divers can observe the orange cup corals expanding their polyps to catch their unfortunate prey. But as they say, what goes around certainly comes around – take a closer look and you may also see sea snails feasting on the polyps of these amazing orange cup corals! Divers can start the dive at the mooring line, swimming out to the twin towers and back to the mooring. Alternatively, divers are able to go to the west island which is another good divesite to explore! The night dives at Koh Haa-Lagoon are not to be missed – divers will get to see the orange cup corals expand their beautiful polyps. But look out for currents outside the bay especially on the night dives.

Koh Haa Lagoon is often dived on a Phi Phi Overnight Trip or Liveaboard Trip to the south Andamansea.
