Summit the tallest mountain in the Australian Capital Territory for sweeping alpine views and a true wilderness experience.
Little Bimberi rises to 1,912 metres, making it the highest point in the Australian Capital Territory. Located deep in Namadgi National Park within the Bimberi Range, the mountain offers hikers a genuine alpine challenge without leaving the ACT. Granite tors, snow-gum woodlands and expansive views across the Australian Alps reward those who reach the summit.
Access begins from Canberra, roughly 90 minutes’ drive south via the Tidbinbilla Road and then Mount Franklin Road into Namadgi National Park. The trailhead lies near the locked gate on Mount Franklin Road, close to the former Mount Franklin ski area. A high-clearance vehicle is recommended for the final unsealed sections, especially after rain. No public transport reaches the park boundary, so private vehicle or organised tour is required.
The out-and-back route covers approximately 22 kilometres with 800 metres of elevation gain. Most walkers take eight to ten hours. The path follows old fire trails before climbing a steep ridge through snow gum and alpine herbfield. Navigation is straightforward on the main track, though side spurs can confuse in poor visibility. Carry a topographic map and compass or GPS.
Late spring through autumn (October to May) provides the most reliable conditions. Wildflowers peak in December and January, while March and April bring cooler temperatures and fewer insects. Winter visits are possible but demand snow and ice experience plus appropriate gear; the road is often closed by snow.
Above the treeline, hardy shrubs and cushion plants survive harsh winds. Look for eastern grey kangaroos at lower elevations and wedge-tailed eagles soaring overhead. On clear days the summit panorama includes Mount Kosciuszko to the south-west and the Brindabella Range to the north.
Combine a Little Bimberi summit with a night at one of Namadgi’s campgrounds for a complete alpine weekend.

It is a strenuous full-day walk suitable for experienced bushwalkers with good fitness. The track is unformed in places and the distance is long.
No permit is required for day walks, but overnight stays in the backcountry need a camping permit from ACT Parks.
Coverage is patchy once you leave the Mount Franklin Road; do not rely on a phone for navigation or emergencies.
The long distance and steep sections make it unsuitable for young children or novice walkers. Consider shorter Namadgi walks first.
Turn back immediately. The exposed ridge offers little shelter and lightning risk is high above the treeline.
