12 Unique Underwater Wonders in Oceania for the American Diver

5. Tufi Fjords, Papua New Guinea

The Tufi Fjords present a rare combination of geological grandeur and marine abundance. Carved by ancient volcanic activity along Papua New Guinea’s northeast coast, these fjords offer a striking backdrop for underwater adventures. Here, divers encounter lush coral gardens—alive with clownfish, sea horses, and pygmy pipehorses—as well as dramatic drop-offs, WWII wrecks, and even hidden caves. The region is famous for “muck diving,” where macro photographers hunt for nudibranchs and smaller critters in sediment-rich shallows. Tufi’s embrace of both ocean and rainforest adds another layer of intrigue; many visitors split their time between world-class reefs and cultural tours in local villages. For those seeking a blend of biodiversity and scenic drama far from the crowds, the Tufi Fjords fit the bill comfortably.
