Tufi Fjords

The Tufi fjords are among the most unusual dive environments on the planet, a series of drowned river valleys cutting deep into Papua New Guinea's northern coastline where vertical walls plunge hundreds of metres into ink-black depths. These tropical rias were formed by tectonic subsidence and volcanic activity, and their extreme depth and sheltered nature create diving conditions found nowhere else: sheer cliff-face walls draped in ancient black coral, pristine soft coral gardens, and macro life of extraordinary rarity, all in mirror-calm water with virtually no other divers. The small aircraft from Port Moresby landed on a grass strip perched above the fjords, and I was underwater within two hours. The first dive was on the wall of the main fjord, entering from a wooden platform at the resort and descending immediately into forty metres of visibility. The wall dropped vertically from the surface, dark volcanic rock colonised by sponges and soft coral from the first metre. At fifteen metres, the first black coral tree appeared, its delicate branches extending over a metre from the wall into the still water. These trees, normally found at depths beyond recreational limits, thrive in the low-light conditions of the fjord's steep walls. At twenty-five metres I paused at a ledge where an enormous gorgonian fan spread from the wall, its surface hosting two pygmy seahorses that our guide located with practiced ease. The wall below continued into darkness beyond thirty metres, and the guides spoke of hammerhead sightings at the fjord entrance where the sheltered waters meet the open Solomon Sea. The afternoon dive moved to the fjord floor for muck diving on volcanic sand at sixteen metres. The critter hunting here rivals anything in the Coral Triangle. Within a single hour I photographed a paddle-flap Rhinopias, its body a canvas of purple and white cryptic patterns; two flamboyant cuttlefish walking across the sand in their characteristic gait, their skin pulsing with colour; and an Ambon scorpionfish so perfectly camouflaged that only our guide's trained eye could locate it. What defines Tufi more than any single species is the isolation. In a week of diving I saw no other dive boats, no other divers, no discarded fishing line, no anchor damage. The marine life has never been pressured by human activity, and it shows in the behaviour of every creature. Fish do not flee. Cuttlefish do not retreat. Sharks approach rather than depart. This is diving as it existed before the dive industry discovered most of the tropics. The fjords themselves are hauntingly beautiful above water as well, their steep jungle walls rising from mirror-still waters where local outrigger canoes are the only traffic. Tufi offers the rare experience of genuine frontier diving, technically accessible but practically unknown, in one of the ocean's most singular environments.
