Koh - Raja Ampat

Koh offers a quieter dive, often bypassed for Raja Ampat’s louder attractions, but we think it’s worth a look. The Ocellated Cardinalfish are everywhere, darting in and out of the corals, and we’ve spent entire safety stops just watching them. Keep an eye out for the Snakehead Cowrie; they’re more elusive, but we’ve spotted them tucked away in crevices. It's a relaxed drift, suitable for divers who prefer exploring the smaller stuff over big pelagics. We’d suggest it as a good second dive of the day, when you want to slow down and really observe.
