Papua New Guinea (PNG) is one of the last truly wild frontiers on Earth. Covering the eastern half of the world's second-largest island plus over 600 offshore islands, PNG contains some of the most extreme biodiversity on the planet — much of it barely catalogued. Scientists believe thousands of species remain undiscovered in its highland forests. For wildlife travelers, PNG is the ultimate destination.
Birds of Paradise
PNG is the global epicenter of the birds of paradise — 38 of the world's 43 species are found across the island of New Guinea and its surrounding island groups. These are among the most spectacular birds on Earth, with elaborate plumage displays evolved through millions of years of sexual selection. Males perform extraordinary courtship dances — some hanging upside down from branches, others inflating iridescent breast shields, and others clearing and decorating forest stages.
Key species and where to see them in PNG:
- Raggiana Bird of Paradise (the national symbol) — Found in the Eastern Highlands and Tari Valley. Males display at dawn from treetop leks.
- Greater Bird of Paradise — Native to the lowland rainforests of southern New Guinea, featuring golden plumes cascading from its flanks.
- King of Saxony Bird of Paradise — Highland forests. Males feature two bizarre head plumes extending twice their body length.
- Blue Bird of Paradise — Endemic to the central highlands of PNG. Famous for its inverted courtship display and deep blue plumage.
Specialized birdwatching lodges in the Highlands (such as Ambua Lodge and Kumul Lodge) cater specifically to birders, with local guides who monitor specific display trees.
Marine Biodiversity
PNG's coral reefs sit within the Coral Triangle — the global epicenter of marine biodiversity. The reefs around Milne Bay, Kimbe Bay, and the Bismarck Sea harbor:
- Over 2,000 species of reef fish
- 600+ species of hard coral — more species diversity than the Great Barrier Reef
- Manta rays, whale sharks, hammerhead sharks, and massive schools of pelagic fish
- Historically significant WWII wrecks fully integrated into living reef ecosystems
Diving in PNG is world-class, offering sheer species density. Liveaboard dive vessels and resort operations base out of Madang, Kavieng, and Milne Bay.
Unique Mammals
- Tree kangaroos: PNG is home to several rare species of tree kangaroo — arboreal marsupials adapted to life in the rainforest canopy. The Matschie's tree kangaroo and Goodfellow's tree kangaroo are notable examples with striking chestnut and golden coloration.
- Echidnas: The eastern long-beaked echidna — one of the world's few surviving monotremes (egg-laying mammals) — lives in PNG's highland forests.
- Cuscus: Arboreal marsupials with prehensile tails found across the island chain.
- Flying foxes: Large fruit bats with wingspans reaching over one meter.
Rainforest — The Third Largest on Earth
PNG contains part of the world's third-largest continuous tropical rainforest (after the Amazon and Congo), covering roughly 70% of the country's land area. Much of it remains untamed and dense. The rainforest stores massive amounts of carbon and harbors undiscovered species — new species of frogs, insects, and flora are described regularly. The Kokoda Track (a 96 km historic WWII trail through the Owen Stanley Range) cuts directly through primary rainforest ecosystems.
Practical Information
- Getting there: Air Niugini operates international flights into Port Moresby from destinations including Singapore, Manila, Tokyo, Cairns, Brisbane, and Sydney.
- Safety & Logistics: Traveling in PNG requires structured advance planning. Port Moresby and main urban centers require standard urban security precautions — arrange ground transport through trusted operators. Nature reserves and rural areas are best experienced with accredited local guides.
- Costs: Logistics in PNG reflect its remote nature. Guided eco-lodges and highland nature tours typically cost $250–$450/day per person. Liveaboard diving ranges from $350–$550/day.
- When to go: May–November (the drier season) is generally optimal for highland trekking and birdwatching. Marine diving conditions operate year-round depending on the region.
Papua New Guinea is a wild and untamed destination. For wildlife enthusiasts, divers, and travelers seeking raw natural environments, it offers natural experiences found nowhere else on earth.
