The Cathedral (Kimbe) Dive Site
Site Overview
The Cathedral (Kimbe), within the Kimbe Bay (New Britain – Coral Hotspot) of Papua New Guinea, is one of the region's most rewarding dive sites and a highlight of any Coral Triangle diving itinerary. An underwater cavern swim-through filled with glassfish, batfish, and moray eels, a dramatic change of pace from the open reefs. Geographically the site features cavern and swim-through and wall formations built from rock and coral substrate, dropping from a shallow top of around 8 metres to a maximum depth of about 30 metres, with an average working depth near 18 metres. Visibility is typically excellent, ranging from 12 to 28 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Glassfish (Parapriacanthus sp.), Batfish (Platax sp.), Moray Eel (Gymnothorax sp.), Bigeye (Priacanthus sp.), Soldierfish (Myripristis sp.), Clownfish (Amphiprion 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 The Cathedral (Kimbe) one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. The Cathedral (Kimbe) 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.
Dive Briefing
"Your dive at The Cathedral (Kimbe) begins with a controlled descent along the mooring line or wall, depending on the current on the day. You enter the cavern with your torch and gather inside among the glassfish, then exit through the swim-through and ascend slowly. Plan to spend the deepest portion of the dive along the cavern between 8 and 18 metres, where the rock is most colourful and the larger fish congregate. Stay with your guide inside the cavern, keep your torch ready, and ascend slowly watching for other groups. Mid-water, watch the blue beyond the wall for passing Glassfish (Parapriacanthus sp.) and other pelagics, and keep an eye on your no-decompression limits given the depths involved. Ascend slowly with a safety stop at five metres to off-gas safely. Because The Cathedral (Kimbe) can experience moderate currents and occasionally reduced visibility after heavy rain, dive with a surface marker buoy and always follow your operator's site-specific briefing and emergency plan."

Traveler Notes
Who is this for?
The Cathedral (Kimbe) is aimed at intermediate divers holding at least a Advanced Open Water certification, and it suits those comfortable managing moderate conditions and maintaining neutral buoyancy along cavern terrain. Photographers, marine-life enthusiasts, and experienced divers will find it especially rewarding, while divers uncomfortable in enclosed spaces should choose the open bommies instead. Divers who prefer calm, shallow, zero-current conditions should choose one of Papua New Guinea's sheltered house reefs or lagoons instead, and anyone without the recommended certification should complete a check-out dive with a local operator first.
For Non-Divers
Non-divers can snorkel the shallow entrance or relax at the resort while divers explore the cavern.
