The Boulari Pass Reserve is a premier marine protected area located near Nouméa, encompassing a critical breach in the New Caledonian barrier reef. This pass acts as a vital gateway connecting the vast open Pacific with the calm lagoon waters, creating a nutrient-rich environment that attracts an abundance of megafauna. It is world-renowned for its manta ray sightings, as these majestic creatures frequent the pass for cleaning and feeding. Divers and snorkelers are also drawn here by the presence of various shark species, including grey reef sharks, and massive schools of barracuda and trevally. The area experiences powerful tidal currents, making it an exhilarating spot for drift diving. During the winter months, the pass serves as a navigational corridor for migrating humpback whales. As a key component of the UNESCO World Heritage-listed lagoons of New Caledonia, the Boulari Pass Reserve is essential for the conservation of large pelagic species and the overall health of the territorial marine ecosystem.

📋 Practical info
Best season
The best time is the dry season from April to November, when currents are weaker and visibility is good. From December to March stronger currents and cyclones may occur.
Best time of day
The morning tide often brings nutrient-rich water, attracting manta rays and sharks into the pass. Afternoon hours before sunset can also yield good sightings.
Etiquette
Do not dive directly into the current; use the calmer edge areas. Do not touch manta rays or sharks, and do not block their escape routes.
What to bring
A strong dive torch is useful to see colors in deeper passages. Use a current compass and a signaling device for safety.
Getting there
Boulari Pass lies off the coast of New Caledonia and is only accessible by boat. Dive bases in Nouméa offer trips to this famous dive site.
What to expect
Large marine animals are not guaranteed; you may need to plan multiple dives to see manta rays or sharks. Drift and observe the current - the animals often come on their own.
