Garove Island (Witu crater) Dive Site

Site Overview

Garove Island (Witu crater), within the Witu Islands (North of Kimbe) of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. Diving inside an extinct volcanic caldera whose warm water hosts frogfish, seahorses, nudibranchs, and unique sponge formations thriving on the geothermal seeps. Geographically the site features crater and slope and wall formations built from sand and rubble and coral substrate, dropping from a shallow top of around 5 metres to a maximum depth of about 30 metres, with an average working depth near 16 metres. Visibility is typically excellent, ranging from 12 to 28 metres, while water temperatures hold between 28 and 31 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Frogfish (Antennarius sp.), Seahorse (Hippocampus sp.), Nudibranch (Nudibranchia), Sponge (Porifera), Ghost Pipefish (Solenostomus sp.), Mandarinfish (Synchiropus splendidus), 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 Garove Island (Witu crater) one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Garove Island (Witu crater) is best enjoyed as part of a boat programme out of Kimbe, 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.
