Pyramid Mountain: Hiking the ACT’s Southernmost Peak

Why Pyramid Mountain Stands Out

Pyramid Mountain rises sharply from the rolling eucalypt forests of southern Australian Capital Territory, offering hikers a true summit experience without the crowds of more famous ACT peaks. Its distinctive triangular profile gives the mountain its name and provides 360-degree panoramas that stretch from the Canberra skyline to the snow gums of the Brindabellas and across the NSW border. The summit rewards visitors with a sense of isolation rare so close to the capital.

Getting There

Access begins from Canberra’s southern suburbs. Drive south on the Monaro Highway, then turn west onto Naas Road before following signs toward the Mount Clear camping area in Namadgi National Park. A high-clearance vehicle is recommended for the final unsealed stretch. The trailhead sits at the end of a rough management track; park responsibly and do not block gates.

The Hike to the Summit

The most direct route follows an old fire trail that climbs steadily through stringybark woodland before emerging onto open grassy slopes. After roughly three kilometres the path steepens into a rocky scramble near the top. Allow four to six hours return for the full day trip, including time at the summit cairn. Carry a topographic map and GPS as mobile reception is patchy.

What to Expect on the Trail

• Native wildlife including eastern grey kangaroos, wedge-tailed eagles and occasional sightings of the elusive spotted-tailed quoll.
• Seasonal wildflower displays in spring, particularly along the lower sections of the route.
• Stunning vistas of the Cotter Catchment and the distant peaks of Kosciuszko National Park on clear days.

Best Time to Visit

Autumn and spring offer the most comfortable temperatures and reliable water sources along the route. Summer brings hot, dry conditions and increased bushfire risk, while winter can deliver snow and ice on the upper slopes. Always check the ACT Parks and Conservation Service alerts before setting out.

Nearby Places Worth Exploring

Combine the hike with a visit to the historic Yankee Hat rock-art site or the wetlands of the Gudgenby River valley, both within Namadgi National Park. The nearby village of Tharwa provides the last reliable fuel and supplies before heading into the park.
