Tackle the remote trails and sweeping alpine views of this rugged spur in Namadgi National Park.
Flat Rock Spur rises as a prominent ridge in the Brindabella Ranges, offering hikers a genuine sense of wilderness within easy reach of Canberra. Its exposed granite outcrops and open eucalypt woodland deliver uninterrupted panoramas across the Cotter Valley and distant snow-capped peaks of the Snowy Mountains. Unlike more crowded lookouts, the spur retains a quiet, untouched character that rewards those prepared for a full-day bushwalk.
Drive south from Canberra via the Cotter Road, then turn onto the unsealed Brindabella Road. Continue past Mount Franklin until the marked trailhead near the spur’s northern end. A high-clearance vehicle is recommended for the final gravel section, especially after rain. From the car park, the main route follows a faint fire trail that climbs steadily through stringybark forest before emerging onto the rocky crest.
April to June and September to November provide the most comfortable temperatures and clearer skies. Summer brings intense heat and bushfire risk, while winter can close access roads with snow or ice. Always check current conditions before setting out.
The primary draw is the 8-kilometre return ridge walk that gains roughly 400 metres in elevation. Along the way, granite tors provide natural rest stops and vantage points for spotting wedge-tailed eagles. At the southern high point, 360-degree views encompass the entire ACT western ranges. Experienced walkers can extend the day by linking to the nearby Mount Gingera trail for an overnight camp at the saddle.
Combine your visit with a stop at the historic Cotter Dam or the Tidbinbilla Nature Reserve, both less than an hour’s drive away. The same road continues to the Mount Franklin ski area in winter, offering seasonal variety for repeat visitors.
