Koh Haa #3
Koh Haa #3 is the island with the white sand beach that closes off the lagoon. On its west side a steep slope covered in plate corals runs down to about 18 m, turning into a wall at each end, where pinnacles draped in soft coral and glassfish rise from the sand. The central part of the site is shallow, which is why instructors use the 'back of #3' for training and navigation practice.
depth: 3–18 m
