Baudisson Bay Dive Site
Site Overview
Baudisson Bay, 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. A calm lagoon dive among mangroves with seahorses, pipefish, and good training and night macro opportunities. Geographically the site features lagoon and slope and sand formations built from sand and rubble and mangrove substrate, dropping from a shallow top of around 2 metres to a maximum depth of about 16 metres, with an average working depth near 8 metres. Visibility is typically excellent, ranging from 8 to 18 metres, while water temperatures hold between 27 and 30 degrees Celsius year-round. The marine life is the headline attraction. Divers routinely encounter Seahorse (Hippocampus sp.), Pipefish (Syngnathidae), Nudibranch (Nudibranchia), Ghost Pipefish (Solenostomus sp.), Clownfish (Amphiprion sp.), Anemone Shrimp (Periclimenes 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 Baudisson Bay one of the most reliable places in the country to see both abundant macro life and large pelagic visitors on a single dive. Baudisson Bay 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.
Dive Briefing
"Your dive at Baudisson Bay begins with a controlled descent along the mooring line or wall, depending on the current on the day. You descend onto the shallow slope and search the mangrove roots and sand for seahorses and pipefish, then ascend gently. Plan to spend the deepest portion of the dive along the lagoon between 2 and 8 metres, where the sand is most colourful and the larger fish congregate. No hooking is needed in the calm lagoon; maintain neutral buoyancy and avoid stirring the silt. Mid-water, watch the blue beyond the wall for passing Seahorse (Hippocampus 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 Baudisson Bay can experience mild 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?
Baudisson Bay is aimed at beginner divers holding at least a Open Water certification, and it suits those comfortable managing mild conditions and maintaining neutral buoyancy along lagoon terrain. Photographers, marine-life enthusiasts, and experienced divers will find it especially rewarding, while new divers, training groups, and macro photographers will love it, while pelagic fans should head to the pinnacles. 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 kayak the mangroves or relax at the resort while divers hunt macro in the bay.
