Boat access from Nouméa is long, and swell plus pass flow make this better for confident divers than casual lagoon outings.

About Passe de Mato

Passe de Mato is an outer-barrier pass in the deep south that rewards confident boat divers. The site is defined by a wall and blue-water channel, with reef fish, macro life, and gorgonian growth on the structure. Pelagic life can move through the pass, but swell and tide make the site less forgiving than sheltered lagoon dives. Treat it as a planned boat day rather than a casual stop, and pick a calmer window if you want the cleanest conditions.
