Why dive here
With 116+ marine species recorded in the area - including dugongs, eagle rays, great white sharks, manta rays and mobula rays (devil rays) - Les Pléiades du Sud offers some of Loyalty Islands's richest diving. Water ranges 24-29°C, warmest January, February, March.
Les Pléiades du Sud holds a special place for us in New Caledonia’s Loyalty Islands. While many New Cal sites feel remote, diving here with Pierre Kaouma adds a genuine local flavour. It’s not just about the underwater; it’s the whole quiet experience of getting there, then dropping into what feels like your own private aquarium. We've found the corals here surprisingly vibrant, even after some regional bleaching events. Keep an eye out for the smaller stuff – the real stars, for us, are the tiny residents. We’ve had great luck spotting the Bridled Goby darting around, and the Acropora Coral Crab can be tricky to spot but worth the effort. The reef itself feels healthy, with a good mix of hard corals providing shelter. If you're patient, you might even spot a Freckled Anglerfish tucked away. It’s a site that rewards slow diving, letting you really absorb the details. We'd suggest going in the morning; the light can be lovely as it filters through the shallows. This is a perfect spot for macro enthusiasts and anyone looking for a relaxed, unhurried dive away from any crowds.
