The Princess May Ranges are a little-known mountain area in remote northern Western Australia, forming part of the broader Wunaamin Miliwundi Ranges. Low by global standards but striking in an outback setting, they rise from flat country into rugged ridges, rocky slopes and isolated high points. For travellers, the appeal is not crowded trails or famous summits, but space, silence and a true sense of remoteness. Mount Anderdon is the best-known named peak, and the whole range suits visitors looking for a wild, off-the-beaten-track landscape rather than a developed alpine destination.
The Princess May Ranges lie in northern Western Australia, within the Kimberley region and as part of the Wunaamin Miliwundi Ranges system. They occupy a compact area of about 530 km², with a rough north-south to northwest-southeast mountain trend typical of the broader range country. The landscape is isolated and sparsely populated, with the ranges standing apart from major settlement and road networks. There are no major sub-ranges listed, and the area is best understood as one small component of the larger Wunaamin Miliwundi uplands rather than a standalone alpine chain.
The Princess May Ranges belong to an ancient Australian landscape shaped by deep geological time rather than recent mountain building. Like much of the Kimberley, the rocks are old and heavily weathered, with resistant ridges standing above surrounding lowlands after long periods of erosion. The range is not a young, high fold mountain system; instead, it reflects uplifted and dissected terrain that has been worn down over immense spans of time. Rock types in the wider region commonly include hard sedimentary and metamorphic units, with steep slopes, cliffs and broken outcrops giving the range its rugged character.
Mount Anderdon is the highest named peak associated with the Princess May Ranges at 484 m. While modest in elevation, it is significant as the range’s best-known summit and a reference point for travellers exploring this remote part of Western Australia. In a region where the land is generally low and open, even a few hundred metres of relief can create distinct ridgelines, viewpoints and rough approaches. For mountaineers, the interest lies less in altitude and more in navigation, isolation and the challenge of reaching a seldom-visited summit area.
There are no widely developed long-distance trekking routes or hut-to-hut systems in the Princess May Ranges, so most visits are expedition-style rather than trail-based. Travellers usually combine the ranges with broader Kimberley outback travel, using 4WD access where available and then moving on foot through rough country. Expect scrub, uneven ground and limited signage rather than marked paths. This is best suited to experienced bushwalkers who are comfortable with self-reliance, route-finding and carrying all supplies in a remote environment with little or no visitor infrastructure.
The Princess May Ranges are not a technical alpine climbing destination, but they can still demand careful movement over broken rock, steep slopes and remote terrain. There are no standard graded routes or famous rock-climbing lines, and objectives are generally exploratory rather than route-specific. The main challenge is navigation and self-sufficiency, not altitude or glacier travel. The best time for mountain travel is usually the dry season, when access is easier and heat, flooding and slippery surfaces are less severe. This range suits experienced outback walkers more than first-time mountain climbers.
The ranges sit within the tropical north of Western Australia, where ecological zones shift from open woodland and savanna on lower ground to rockier, more sheltered habitats on slopes and ridges. Seasonal creeks, spinifex, shrubs and hardy trees dominate much of the landscape, with wildlife adapted to heat, dryness and periodic heavy rain. The broader Kimberley region is known for rich biodiversity and remote protected landscapes, though specific park boundaries around the Princess May Ranges may be limited or overlapping with wider conservation areas. Visitors should expect a wild, lightly developed environment.
The Princess May Ranges have a tropical monsoonal climate with a strong wet and dry season pattern. The wet season brings heat, humidity, storms and difficult access, while the dry season is generally more comfortable for travel, camping and overland approaches. Daytime temperatures can still be high, and exposed slopes offer little shade. After rain, creeks and tracks may become impassable, so timing matters as much as fitness. For most visitors, the dry season is the safest and most practical window for exploring the range.
Q: How do I get mobile or satellite coverage in the Princess May Ranges?
A: Do not rely on mobile service in the range itself; coverage is often patchy or absent once you leave settled roads. A satellite phone or personal locator beacon is strongly recommended for any serious trip, along with a pre-arranged check-in plan. Carry offline maps and a backup power source, because navigation and emergency contact may both depend on your own equipment.
Q: Can I camp in the Princess May Ranges, or are there huts and refuges?
A: Expect expedition-style camping rather than huts, refuges or serviced campsites. You will usually need to be fully self-contained with water, shelter, food and navigation gear. Choose durable camps well away from drainage lines, and plan for hot conditions, insects and limited shade. If you are using a 4WD-supported approach, confirm where vehicles can safely be left before setting out on foot.
Q: Do I need permits or permission to climb in the Princess May Ranges?
A: Permit requirements can vary depending on the exact access route, land tenure and whether you cross Aboriginal land or other restricted areas. Check with local authorities and traditional owners well before travel, especially if you plan to leave public roads or enter remote country. Do not assume open access, and be prepared for route-specific permissions or access conditions.
Q: Can I climb the Princess May Ranges independently, or do I need a guide?
A: Independent travel is generally the norm for experienced outback visitors, and there is no known requirement for a guide or expedition agency. That said, solo travel is a poor choice unless you are highly self-reliant, because rescue response can be slow and navigation is demanding. A guided trip may be wise for first-time visitors to remote Kimberley terrain.
Q: How do I reach the Princess May Ranges, and how long is the approach to base camp?
A: Access is typically via remote roads from Kimberley towns and air access through regional airports, followed by a long overland approach. The final leg may require a 4WD, and in some cases walking in from the nearest vehicle access point. There is no standard base-camp trail, so approach times vary widely and can be substantial. Pack animals are not a normal feature here.
Q: Is the Princess May Ranges climb suitable for a first-time visitor to remote mountains?
A: The range is better for experienced bushwalkers than for first-time remote-mountain climbers. The terrain is not technically hard, but the real demands are heat management, navigation, water planning and self-rescue. If you are new to isolated outback travel, start with a shorter, well-supported trip elsewhere before attempting a solo or unsupported visit here.
