Gadji and the Northern Reefs form the boat-access diving zone on the northern side of Île des Pins in New Caledonia's lagoon. All eight sites are reached exclusively by boat, and the range runs from a six-metre beginner reef at Daa Djare to a wall and drift site at Le Banc de Sable that descends to fifty metres. The area is particularly noted for its cave diving: Grottes de Gadji features cave openings at around twenty to twenty-three metres requiring solid buoyancy control, while an underwater corridor grants access to a separate cave system in the area. Species recorded include bumphead parrotfish, nurse sharks, whitetip reef sharks, Napoleon wrasse, garden eels, sea kraits, and a variety of nudibranchs. Two operators are based nearby.





Monthly water temperature across Gadji & Northern Reefs's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperatures follow a clear seasonal pattern, peaking in the austral summer and dropping to their coolest from July to October. The variety of depths and site types means something is accessible year-round, though the deeper wall and drift dives are best reserved for conditions when visibility stretches toward its upper range.
