    Iriru is one of those Bora Bora spots that we always carve out time for. It’s not about the big pelagics here, though you might get lucky with a passing eagle ray. This site is pure macro magic, a kaleidoscope of reef fish activity that demands a slow drift. We love finding a sandy patch and just kneeling to watch the show. You'll see Ornamented Wrasse darting through coral heads, and the Undulated Morays are usually out, just watching the world go by from their crevices. Keep an eye out for Two-spot Bristletooth grazing the reef, and if you’re patient, a False-eyed Pufferfish will often let you get close. We’ve had some fantastic encounters with Arc-eye Hawkfish perched on coral branches, practically posing for photos. The light here, filtering down into the shallows, really makes the colours pop. It’s a perfect spot for photographers looking for those detailed reef shots. We’d suggest going in the morning; the light is softer and the fish activity always seems a bit livelier before the afternoon boat traffic picks up.
