    StandoutExceptional marine biodiversity

    Nioumachoua Reef delivers. You drop onto a hard coral plateau, usually seeing a couple of grey reef sharks patrolling the deeper edge right away. Our favourite here is drifting along the wall, keeping an eye out for the smaller stuff – we've spotted the Bristle-toothed Surgeonfish and those tiny, perfectly camouflaged Blotchfin Scorpionfish tucked into the coral. What really makes Nioumachoua special, though, is the sheer density of fish. Not just big schools, but the variety in every crevice. We often find ourselves just hanging out at 15 metres, watching the dusky farmerfish dart in and out, or catching a glimpse of the Point-head Maori wrasse weaving through the bommies. It's an intermediate dive, sometimes with a gentle drift, but nothing too taxing. We'd suggest aiming for a morning dive when the light hits the coral just right and the sharks tend to be more active. You’ll leave feeling like you’ve been somewhere genuinely untouched.
