Blupblup Island Dive Site

Site Overview

Blupblup Island, within the Kavieng & New Ireland – Pelagic & Walls of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. Volcanic black-sand diving with fields of garden eels, stingrays, and unusual macro life. Geographically the site features slope and sand and reef formations built from black-sand and rubble and coral substrate, dropping from a shallow top of around 3 metres to a maximum depth of about 25 metres, with an average working depth near 14 metres. Visibility is typically excellent, ranging from 10 to 22 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Garden Eel (Heteroconger sp.), Stingray (Dasyatidae), Nudibranch (Nudibranchia), Ghost Pipefish (Solenostomus sp.), Frogfish (Antennarius sp.), Octopus (Octopus sp.), 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 Blupblup Island one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Blupblup Island is best enjoyed as part of a boat programme out of Kavieng, 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.
