About Koh Haa #4
Koh Haa #4 is a sheltered Koh Haa reef and wall dive that starts in very gentle shallow water before dropping over coral slope, rock, and sandy patches on the outer side of the island. It is widely used as an easy scenic site, but the southern wall and cave features add more interest for divers looking beyond the lagoon-style shallows.
