Boulari Plateau Manta in Prony Bay is exactly what it sounds like, a manta ray magnet. We're talking proper reef mantas, not just a passing glimpse. This plateau, sitting at a comfortable 13 metres, acts as a cleaning station, so you settle in and watch the show. We’ve had dives here where we barely moved, just observing these gentle giants glide in, hover over the coral heads, and get serviced by the smaller fish. The current can be stiff, sometimes really ripping, so it’s a drift dive for sure. You’ll be swept along the edge of the plateau, eyes peeled, then you hit the sweet spot. When the mantas are here, they're the main event. But don’t forget to look around. Schools of blue and gold fusiliers are everywhere, and we’ve seen some hefty grey reef sharks patrolling the deeper edges. Keep an eye out for orbicular batfish too, they often hang around the reef crest. Our pick for timing is definitely early morning, before any boat traffic picks up. The water generally holds 19 metres of visibility, a clear, warm blue that just feels like New Caledonia. This site is for divers who appreciate a reliable big animal encounter and don't mind a bit of a current. It's a drift that delivers.
