Bismarck Range

The Bismarck Range is a mountain range in the central highlands of Papua New Guinea and forms part of the island’s mountainous spine. It includes several high peaks, the best known of which rises to over 4,500 metres.

The range offers high-altitude terrain and is a destination for mountaineering and extended treks rather than mass tourism; conditions can be remote and logistically demanding. Access typically requires travel from provincial centres followed by multi-day approaches to higher slopes.

European explorers and colonial administrators gave the range its modern name during the late 19th century German colonial period. The area has since remained sparsely populated and has been used locally for subsistence activities in lower valleys while higher ridges are largely wild.

Geographically it lies within the New Guinea Highlands of Papua New Guinea, forming part of the island’s central mountain systems and providing major watershed divides.

• High peaks: contains peaks that exceed 4,000 metres, with alpine terrain that attracts experienced trekkers and mountaineers.

What to See#

• Mount Wilhelm: the highest summit in the range and in Papua New Guinea at 4,509 metres above sea level, commonly climbed by mountain trekkers.

• Treat the Bismarck Range as a remote, expedition area: travel only with experienced local guides or tour operators based in Papua New Guinea who can arrange permits, logistics and village contacts.
• Plan travel through regional hubs (e.g., Lae or Madang) and allow multiple days for transport and acclimatization - access is by small aircraft, boat or extended overland trekking and schedules can be unpredictable.
