Kimbe Bay diving is many people's first taste of Papua New Guinea, and it sets a high bar. The bay sits on the north coast of West New Britain, a long volcanic island east of the PNG mainland. Its deep water is scattered with seamounts and reefs that rise close to the surface, and the corals on them are among the healthiest in the region. If you want classic Coral Triangle reef diving with very few other boats around, this is the place to start.
What makes Kimbe Bay special
The bay drops to great depth only a short boat ride from shore. Out in that deep water, isolated pinnacles and seamounts (locally called bommies) climb from the blue to within a few metres of the surface. Because they stand alone in open water, they attract schooling fish and pelagic visitors, and their slopes are covered in hard coral, barrel sponges and some of the largest sea fans you will ever see.
Closer to shore there are fringing reefs, walls and sheltered bays where the diving is gentler. Between the two, a week in Kimbe Bay can include drift-free reef dives, steep walls, pinnacle tops buzzing with anthias and the occasional muck dive near the jetty.
Kimbe Bay dive sites to know
Sites change name from one operator to the next, so think in types rather than a fixed list:
- Seamounts and pinnacles. The signature Kimbe Bay dive. Descend in blue water, circle the pinnacle and finish on a shallow top full of colour. Barracuda, jacks and batfish often hang off the current side.
- Walls. Vertical faces with sea fans, whip corals and crinoids. Good for wide-angle photography and for divers who like depth with a clear reference.
- Offshore islands. Small islands in the bay have reefs on every side, so a sheltered side can usually be found whatever the wind is doing.
- House reef and jetty dives. Shallow, easy and surprisingly rich in small life. Good for a night dive or the day before you fly.
Marine life
Kimbe Bay is known first for its reefs rather than any single animal. Expect dense hard coral cover, soft corals in many colours, huge gorgonian fans and barrel sponges. On the fish side, look for schooling barracuda, jacks, batfish, fusiliers and big clouds of anthias over the pinnacle tops. Reef sharks, turtles and eagle rays turn up regularly.
Small life is everywhere for anyone who slows down: pygmy seahorses on the right fans, nudibranchs, leaf scorpionfish, anemonefish and gobies. Dolphins are often seen in the bay on boat rides, and in some years pilot whales or orcas pass through.
Conditions and diving style
Water is warm year round, typically in the high 20s °C, and visibility on the offshore sites is often excellent. Most diving is from small, fast day boats with two or three dives a day, and many sites begin with a descent in open water to the top of a pinnacle. Currents are usually mild to moderate but can pick up on exposed seamounts.
The bay is sheltered by the island to the south, which helps, but wind still matters. See the best time to dive Papua New Guinea for how the seasons affect New Britain and the other regions.
Resort or liveaboard?
Kimbe Bay has long-established land-based dive resorts, which is one reason it suits a first PNG trip. A resort stay gives you a house reef, day boats to the seamounts and a comfortable base for non-divers.
Liveaboards also use Kimbe Bay as a start or end point, often combining it with the reefs and islands further along New Britain's coast or with routes to Rabaul and Kavieng. If you want to dive the most remote seamounts, compare the options on our Papua New Guinea liveaboards page.
Getting to Kimbe Bay
Fly into Port Moresby, then take a domestic flight to Hoskins, the airport that serves Kimbe Bay. Resorts usually arrange the road transfer from Hoskins. Allow for schedule changes on the domestic leg and avoid tight same-day connections with your international flight. Our Papua New Guinea dive trip planning guide covers visas, flights and what to pack.
Who Kimbe Bay suits
Almost everyone with some experience. Reef lovers and wide-angle photographers will be happiest, but there is enough macro to keep a critter hunter busy. Newer divers can enjoy the sheltered reefs and house reef with a guide, while the deeper seamounts and walls reward those with Advanced Open Water and good buoyancy.
If small, strange animals matter more to you than big reefscapes, look at Milne Bay muck diving as a second stop.
Kimbe Bay diving FAQ
How many days should I spend in Kimbe Bay?
A week of diving lets you see the main seamounts, walls and islands without rushing. Add travel days on each side.
Is Kimbe Bay good for beginners?
The sheltered reefs and house reefs are fine for newer divers with a guide. The offshore seamounts are better with some experience, as descents are in open water and current can pick up.
Can I combine Kimbe Bay with other regions?
Yes. Many divers pair it with Milne Bay or Rabaul, or join a liveaboard that starts or finishes in the area.
