Tackle rugged trails to the ACT’s highest peak amid pristine wilderness just outside Canberra.
Bimberi Wilderness protects a large tract of the Brindabella Range where granite peaks, snow-gum woodlands and subalpine bogs create one of the most intact natural landscapes near any Australian capital city. At 1,913 metres, Bimberi Peak is the highest point in the ACT, offering 360-degree views across the Australian Alps on clear days. The area’s isolation has preserved populations of wombats, gang-gang cockatoos and the rare broad-toothed rat, making every walk a chance to observe wildlife that has largely disappeared from more accessible parks.
The main draw is the full-day return hike to Bimberi Peak via the Oldfields Hut route or the steeper approach from Mount Gingera. Both trails cross open alpine meadows and pass historic stockmen’s huts that provide emergency shelter. Shorter options include the gentle circuit around the upper Cotter River headwaters or a half-day climb of Mount Morgan for sweeping views without the full summit commitment. Off-track navigation through the western section rewards experienced bushwalkers with quiet campsites beside small tarns. All activities require a topographic map and compass; mobile coverage is absent beyond the first few kilometres.
Most visitors start from Canberra, driving south on the Cotter Road then turning onto the unsealed Brindabella Road. A high-clearance vehicle is strongly recommended, especially after rain when clay sections become slippery. The final approach to trailheads involves locked gates; arrange access permission through ACT Parks before departure. There are no facilities inside the wilderness boundary, so carry all water, fuel stoves and waste out with you.
Late spring through autumn (October to May) offers the most reliable conditions. Snow can fall any month above 1,500 metres, and the area is closed during total fire bans. Summer thunderstorms arrive quickly, while autumn brings clear, cool days ideal for long ridge walks. Winter visits are possible for experienced, equipped parties but demand ice axes and awareness of sudden weather changes.
Combine a Bimberi trip with exploration of Namadgi National Park’s Yankee Hat rock-art site or the historic Cotter Dam precinct. Canberra’s national institutions are less than two hours away, allowing visitors to balance wilderness days with museum visits or dining in the capital.

A high-clearance vehicle is recommended; standard cars can reach the general area in dry conditions but may struggle on the final unsealed sections after rain.
Some routes follow faint management tracks and old stock routes, but navigation skills and a good map are essential as signage is minimal.
Yes, but only at established sites or on durable surfaces; no facilities are provided and all waste must be carried out.
Common sightings include eastern grey kangaroos, wombats, crimson rosellas and gang-gang cockatoos, especially near water sources at dawn and dusk.
The terrain and lack of services make it best suited to experienced bushwalkers; novices should join a guided group or start with easier walks in nearby Namadgi.
