Manta Ray Reef (off Nuakata) Dive Site

Site Overview

Manta Ray Reef (off Nuakata), within the Milne Bay – Muck & Reef Diving of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. A reliable manta cleaning station off Nuakata with whitetip reef sharks and barracuda, where mantas hover to be cleaned in season. Geographically the site features reef and ledge and cleaning-station formations built from coral and rock substrate, dropping from a shallow top of around 8 metres to a maximum depth of about 28 metres, with an average working depth near 16 metres. Visibility is typically excellent, ranging from 15 to 30 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Manta Ray (Mobula alfredi), Whitetip Reef Shark (Triaenodon obesus), Barracuda (Sphyraena barracuda), Cleaner Wrasse (Labroides sp.), Hawksbill Turtle (Eretmochelys imbricata), Spotted Eagle Ray (Aetobatus narinari), alongside dense reef fish, invertebrates, and the soft and hard corals that blanket the reef. The mix of nutrient-rich currents and Papua New Guinea's remote, well-protected reefs makes Manta Ray Reef (off Nuakata) one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Manta Ray Reef (off Nuakata) is best enjoyed as part of a boat programme out of Alotau, and it rewards wide-angle photographers, naturalists, and experienced drift divers alike. Papua New Guinea's strong community-based conservation ethos and remoteness help keep the reef pristine, so divers are asked to maintain exemplary buoyancy and respect the fragile marine environment at all times.
