Ao Hin Ngam

We really like Ao Hin Ngam, especially when the light hits just right in the late morning. It’s got a lovely, natural feel to it, a bit more rugged than some of the more manicured sites around Koh Tao. What makes it standout for us are the big, sprawling patches of staghorn coral. They’re everywhere, creating this intricate habitat, and if you take your time, you’ll spot all sorts of small stuff darting in and out. We’ve spent ages here just watching the pink anemonefish. They’re always busy, fiercely guarding their homes. Keep an eye out for blue-spotted stingrays tucked into the sand flats too, especially as you drift away from the main coral bommies. Visibility here can sometimes be a bit variable, particularly after a strong rain, but when it’s good, the water has that lovely warm, green hue that’s classic Koh Tao. We’d suggest this one for divers who appreciate a slower pace, those who like to really observe rather than just cruise past. You won’t find huge pelagics, but the sheer density of reef fish, like the big schools of blue and gold fusiliers, is really impressive. Look for the blackfin barracuda hanging out in the deeper sections, often just watching the world go by.
