Cotter Reserve

Cotter Reserve is a tranquil riverside escape just a 20-minute drive from Canberra’s city centre, offering a refreshing blend of bushland, swimming holes, and picnic spots along the Cotter River. This ACT Parks and Conservation area is beloved by locals for its clear, cool waters and shaded grassy banks, making it an ideal spot to unwind after exploring the capital’s museums and galleries. The reserve’s history as a former water-supply catchment gives it a pristine, protected feel – you’ll hear birdsong and the gentle rush of the river rather than city noise. Whether you’re after a quick dip or a lazy afternoon barbecue, Cotter Reserve feels like a secret slice of the Australian bush, yet it’s remarkably close to town.

Highlights & What to See

• Cotter River Swimming Holes – Plunge into the clear, deep pools that form along the river; the main swimming area near the picnic shelter is popular, but you can find quieter spots upstream.
• Riverside Picnic & BBQ Facilities – Scattered tables, electric barbecues, and plenty of shade make this a perfect spot for a relaxed lunch. Bring your own supplies and enjoy the bush setting.
• Cotter Avenue Walking Track – An easy 1.5 km riverside walk that follows the old water-supply pipeline, offering views of the river and a chance to spot kangaroos and birdlife.
• Historic Cotter Dam – A short walk from the reserve, the original concrete dam (built 1912–1915) is a remnant of Canberra’s early water supply. The lookout provides a glimpse into the area’s engineering past.
• Mountain Biking & Cycling – The reserve connects to the Canberra Centenary Trail and other fire trails, making it a great launch point for a ride through the surrounding bush.

Suggested Time to Spend

Most visitors spend half a day (3–4 hours) at Cotter Reserve, combining a swim, a picnic, and a short walk. If you’re keen on a longer cycle or hike, allow a full day to explore the trails deeper into the Namadgi National Park area. The reserve is especially lovely in the warmer months (October to March), but it’s a peaceful spot year-round for a quiet escape.
