Koh Kai / Chicken Island is a shallow reef stop off Ao Nang with gently sloping coral, easy water, and a relaxed boat-day feel. It is a good fit for beginners and snorkelers, with mild currents, colorful reef fish, and enough coral structure to keep the dive interesting without making it technical. On clear days the site feels straightforward and comfortable, and the shallow profile makes it easy to spend time watching clownfish, parrotfish, moray eels, pufferfish, and stingrays.
