About Koh Haa Lagoon
Koh Haa Lagoon is a boat-access lagoon in the Koh Haa island group, set between limestone islands and a shallow sandy bottom. The site is known for clear water, coral bommies, and calm conditions that work well for beginner divers, snorkelers, and underwater photographers. It is a short, easygoing lagoon dive rather than a deep wall or a current-heavy route, and the shallow reef is rich enough to reward both macro hunting and relaxed fish watching.
