Ko Haa 4
A coral wall to 30 m beside the Lagoon, a drift when the current runs
Ko Haa 4 lies not far from the Lagoon in the Koh Haa group and is a wall dive: a face of coral formations that drops to 30 m, with a system of two connected caves around 15 m. Current is none or light, and when it runs the right way the wall becomes a drift dive.

The dive
The dive follows the wall down towards 30 m, and divers choose their depth along the face. Green turtles, groupers and colourful nudibranchs are the regulars. When the current is right, the group lets it carry them along the face as a drift dive instead.
