Manta Alley - Komodo

Passe de Mato, two hours south of Nouméa, definitely earns its spot. It's an outer channel, so you'll feel the ocean's surge, but that energy brings the big stuff in. We love dropping onto the plateau at 10 metres, then drifting along the wall as it falls to 25 metres. The visibility here, averaging 19 metres, means you can really appreciate the scale. We've seen oceanic manta rays glide past in the blue, and there’s always a chance for a great white, though they’re shy. The reef itself is a mix of staghorn and branch corals, with plenty of macro life if you look closely: Acropora Coral Crabs scuttling, maybe a Striated Locust Lobster peeking out. This is a dive for those who enjoy a bit of current and the thrill of open ocean encounters. Expect a proper channel dive; it's less about lingering in one spot and more about a flowing exploration.
