Koh Haa, near Ao Nang is a boat-reached Krabi reef site with a sheltered lagoon, coral-lined walls, and more exposed outer sections that add variety to the same trip. The calmer inner water works well for snorkeling and relaxed dives, while the outer reef rewards divers who want a little more structure and a broader reef profile.
