Rugged ridgelines above the Murrumbidgee
Overview
Bullen Range Nature Reserve forms a long band of hill country on Canberra’s south-western edge, extending north from Pine Island to the meeting point of the Murrumbidgee and Cotter rivers. Covering about 4,024 hectares, it protects a substantial stretch of the Bullen Range and helps link the Murrumbidgee River corridor with the broader mountain and reserve system to the west and north.
This is a larger and rougher reserve than many of Canberra’s suburban nature parks. Its steep slopes, ridges and river-facing escarpments give it a more remote feel, even though it sits not far from the city.
Highlights
The reserve’s defining feature is the range itself: a rugged line of hills and steep country rising above the western side of the Murrumbidgee. The scenery is shaped by long ridges, broken gullies and rocky sections that create a distinctly dry, bushy character.
One of the standout natural features is Red Rocks Cliff near Kambah Pool, a striking cliff line above the river. Elsewhere, the reserve’s elevated ground and connected bushland give it a strong sense of scale, especially where the hills drop towards the river corridor.
Best Time to Visit
The most comfortable months are generally from autumn through spring, when the cooler air suits the reserve’s exposed slopes and ridgelines. Spring is especially appealing if you enjoy seeing shrubland and dry forest in flower, while the clearer light in autumn and winter tends to sharpen the shape of the range and the surrounding valleys.
Summer can be harsh on these open hills, so the reserve often feels better in the milder parts of the year.
Plants and Animals
Bullen Range protects dry open forest and shrubland on shallow, often sandy soils. These tougher hillside communities suit a reserve defined by steep terrain and exposed ground rather than lush gullies.
The reserve is one of the ACT sites where pale pomaderris is conserved, a vulnerable native shrub that grows in dry open forest and shrubland. Red Rocks Cliff is also an important Peregrine Falcon breeding site, which speaks to the value of the reserve’s rocky escarpments and relatively undisturbed cliff habitat.
