A quiet summit walk in the Australian Capital Territory offering expansive views across the Brindabella Ranges and surrounding bushland.
Mount McKeahnie rises in the northern Brindabella Ranges within the Australian Capital Territory, providing a less-crowded alternative to more famous Canberra day walks. The mountain rewards visitors with sweeping vistas over the Cotter River catchment, distant Canberra skyline, and layered eucalypt forests that change colour with the seasons. Its position on the edge of Namadgi National Park makes it an accessible escape for those seeking genuine wilderness without leaving the territory.
The mountain is reached via the sealed Brindabella Road that leaves the ACT and climbs into the ranges. From Canberra, drivers head west through the suburb of Weston Creek then continue on the Cotter Road before turning onto Brindabella Road. A high-clearance vehicle is useful on the final gravel sections, though standard cars manage in dry conditions. Parking is available at the informal trailhead near the Mount McKeahnie fire trail. No public transport serves the area, so private vehicle or organised tour is required.
The main route follows an old management trail that ascends steadily through tall peppermint gum and snow gum woodland. After roughly two hours of walking the track narrows to a footpad that circles the rocky summit tor. From the top, clear days reveal the full length of the Brindabella Range, the distant peaks of Bimberi and Scabby, and the winding ribbon of the Cotter Reservoir below. The return journey can be varied by descending via the northern spur, adding extra distance and different vegetation zones.
Spring brings colourful displays of native peas and wattles along the lower slopes. In autumn the snow gums take on bronze tones. Keep an eye out for wedge-tailed eagles riding thermals above the ridge and for the distinctive calls of gang-gang cockatoos in the canopy. Eastern grey kangaroos often graze near the trailhead at dawn and dusk.
Autumn (March to May) and spring (September to November) offer the most comfortable temperatures and clearer skies. Summer can bring high fire danger and thunderstorms, while winter occasionally delivers snow on the higher ridges, transforming the walk into a more demanding outing. Always check the ACT bushfire and park alerts before setting out.
Combine the hike with a visit to the historic Cotter Dam or the picnic areas along the Cotter River. The nearby Mount Franklin area offers additional snow-play opportunities in winter, while the long-distance Australian Alps Walking Track passes within a day’s walk for experienced hikers seeking multi-day adventures.

The trail is moderate, with steady elevation gain on a management track followed by a short rocky scramble near the top. Most fit walkers complete the return trip in four to five hours.
Dogs are not permitted because the mountain lies within Namadgi National Park, where pets are prohibited to protect native wildlife.
No reliable water sources exist on the mountain itself. Carry all drinking water from Canberra or the Cotter River area.
Snakes are common in warmer months. Give them space, back away slowly, and wear sturdy boots and long trousers for protection.
No designated campsites exist on the mountain. The nearest legal camping is at the Cotter Campground or further south in Namadgi National Park.
