The Murray Range is a remote highland mountain chain in Papua New Guinea, rising from low tropical valleys to rugged summits above 3,000 metres. Part of the Central Highlands, it offers a dramatic mix of steep ridges, forested slopes and misty uplands that feel far from the coast and even farther from mass tourism. For trekkers and climbers, the appeal is its isolation: quiet approaches, strong local character and a landscape that still feels exploratory. The highest point is Mount Imila, and the range rewards visitors who are prepared for rough logistics and changing mountain conditions.
The Murray Range lies in Papua New Guinea, within the broader Central Highlands of Asia’s island arc region. It stretches across a large upland area of about 12,718 km², with elevations climbing from near sea level in surrounding lowlands to 3,494 m at the highest point. The range is a compact but substantial highland mass rather than a single sharp ridge, with dozens of named mountains spread through steep terrain. It sits within the interior highlands landscape, where valleys, escarpments and forested slopes connect it to neighbouring upland systems and to the wider central mountain spine of the island.
The Murray Range was formed by long-running tectonic uplift linked to the collision and interaction of the Australian and Pacific plate systems in the New Guinea region. Its mountains are geologically young in Himalayan terms, but the landscape has been deeply carved by erosion, river incision and repeated uplift. The range is dominated by hard basement rocks and uplifted highland formations, with steep slopes, narrow ridges and deeply cut valleys. In the highest areas, cooler conditions have supported local glacial and periglacial shaping in the past, leaving a rugged alpine-style relief even in a tropical setting.
Mount Imila is the highest named summit in the range at 2,983 m and the main objective for climbers looking for the range’s top point. Tari Gap, at 2,977 m, is almost as high and is a major high pass and landmark for route planning. Mount Ne (2,887 m) is another important high summit, while Mount Waga (2,537 m) and Mount Kerewa (2,508 m) offer additional high-country objectives. Lower but still notable peaks such as Mount Pulim, Mount Waranubu and Mount Murray help define the range’s rugged skyline and provide trekking and exploratory climbing targets.
Trekking in the Murray Range is best suited to travellers who want remote, off-the-beaten-path highland travel rather than marked tourist trails. Routes are generally local-path based, linking valleys, ridges and high passes, and may require route-finding, village coordination and flexible itineraries. There is no widely known hut network, so most trips are expedition-style and self-supported or arranged with local support. The appeal is the sense of discovery: forest approaches, cool upland camps and broad views from the higher ridges. Expect rough ground, river crossings and limited infrastructure rather than classic lodge trekking.
Mountaineering in the Murray Range is more about rugged highland ascents than technical ice climbing, but the terrain can still be demanding. The main objectives are high summits such as Mount Imila and neighbouring peaks, usually approached by long ridges, steep grassy slopes, forested sections and occasional exposed rock. Difficulty is often moderate in technical terms, but the real challenge is navigation, endurance and self-sufficiency. Conditions can make even straightforward lines slow. The best climbing windows are usually the drier periods, when access is easier and slopes are less slippery.
The Murray Range supports a strong tropical mountain ecosystem, with lower slopes covered in rainforest and higher ground shifting into montane forest, mossy woodland and open upland vegetation. Orchids, tree ferns, pandanus and dense undergrowth are typical in wetter zones, while cooler ridges carry tougher highland plants adapted to wind and cloud. Wildlife is rich but often elusive, with birds of paradise, parrots, possums and other endemic highland species likely to interest nature travellers. The range’s remoteness means many habitats remain relatively intact compared with more accessible mountain areas.
The Murray Range has a humid tropical mountain climate with frequent cloud, heavy rainfall in many months and cooler temperatures as elevation increases. Lower slopes can be hot and wet, while higher ridges are often misty, windy and much colder at night. Trails may become slippery after rain, and river levels can rise quickly. The most practical time for trekking and climbing is usually the drier season, when visibility improves and access is more reliable. Even then, expect sudden showers and plan for wet-weather gear, warm layers and flexible summit timing.
Q: How do I get mobile signal or satellite communication in the Murray Range?
A: Do not rely on normal mobile coverage once you leave settled valleys. In the Murray Range, a satellite phone or satellite messenger is the safest option for check-ins and emergencies. Carry spare batteries and a power bank, and agree on scheduled contact points before departure. Local SIMs may work only near towns or roadheads, not on the mountain itself.
Q: Are there huts or refuges in the Murray Range, or do I need to camp?
A: Plan for expedition-style camping. The range is not known for a developed hut or refuge network, so climbers usually carry tents, cooking gear and all food, or arrange local support where possible. Camps should be chosen with drainage and river safety in mind. If you expect shelter, confirm it locally before setting out, because facilities can be very limited.
Q: Do I need permits, local fees, or special permission to climb here?
A: Access can depend on local land ownership and village agreements, so permission is often more important than a formal park permit. Some areas may involve customary fees, guide payments or community contributions. Check for any restricted zones, especially near borders or sensitive local areas, and confirm access with local contacts before travel. Rules can change by valley.
Q: Can I climb the Murray Range independently, or do I need a guide or agency?
A: Independent travel may be possible for experienced climbers, but local knowledge is strongly recommended because navigation, access and logistics are not straightforward. A guide or expedition contact can help with village permissions, transport and route-finding. Solo climbing is only sensible for very self-reliant mountaineers who are comfortable operating without marked trails, rescue support or reliable communications.
Q: How do I reach the Murray Range, and how long is the approach to base camp?
A: Most trips start from a regional town or airstrip in Papua New Guinea’s highlands, then continue by road where possible and on foot from the last accessible point. Exact approach times vary widely by objective and village access, but reaching a base camp often takes a full day or more after the roadhead. Porters or local carriers may be available in some areas and are useful for heavy loads.
Q: Is the Murray Range suitable for a first-time climber in Papua New Guinea?
A: It can suit a first-time visitor to Papua New Guinea’s mountains only if they already have solid trekking fitness, basic navigation skills and comfort with remote camping. It is not a beginner-friendly place for a first-ever mountain trip, because access is rough and support is limited. Start with a non-technical objective and go with a well-organised local plan if you are new to the region.
