A remote peak offering quiet trails, native forests and sweeping views over Namadgi National Park.
Black Spring Mountain rises in the northern Brindabella Ranges within Namadgi National Park, roughly 50 km southwest of Canberra. Its modest elevation and position on the ACT–NSW border deliver expansive vistas across eucalypt ridges and the Cotter River catchment without the crowds found on more accessible peaks. The mountain forms part of the park’s western wilderness zone, where granite outcrops, snow-gum woodlands and wildflower meadows create a distinctly Australian high-country landscape.
Access begins from the Cotter Road or Uriarra Crossing, then follows Brindabella Road before turning onto the unsealed Mount Franklin Road. A high-clearance vehicle is recommended, especially after rain, as sections become slippery clay. The final approach to the summit area is via a walking track that starts near the old Black Spring hut site; allow 45 minutes from Canberra’s western suburbs in dry conditions.
April to June and September to November offer the most comfortable temperatures and stable track conditions. Summer can bring bushfire risk and heat, while winter snow occasionally closes the higher roads. Wildflowers peak in late spring; autumn delivers golden wattle and changing foliage in the valleys below.
The main route is a 6 km return walk that climbs steadily through snow-gum forest to a broad summit plateau marked by a trig point. From the top, clear days reveal Lake Burrinjuck to the west and the Canberra skyline to the east. Side paths lead to granite tors offering sheltered lunch spots and opportunities to spot wedge-tailed eagles. The area is also popular with experienced mountain bikers on the longer Brindabella fire-trail network.
Visitors may encounter eastern grey kangaroos at dawn, crimson rosellas in the canopy and occasional sightings of the endangered northern corroboree frog in moist gullies. Stay on marked tracks to protect fragile alpine bogs and avoid disturbing breeding birds.
Combine the visit with the historic Cotter Dam visitor centre, the scenic drive to Mount Gingera, or a picnic at the Bendora Arboretum. Canberra’s National Museum and Parliament House are less than an hour away for those extending the day into the capital.
