Wander along a clear mountain stream winding through eucalypt forests and granite outcrops in the Australian Capital Territory’s southern wilderness.
Jacks Creek rises in the Brindabella Range and flows north through Namadgi National Park before joining the Cotter River. Its upper reaches remain largely untouched, offering visitors a genuine sense of remote bushland only an hour from Canberra. The creek carves small pools and riffles between mossy boulders, framed by tall alpine ash and snow gum woodlands that change colour with the seasons.
Several informal tracks follow the creek from the Jacks Creek Fire Trail. Short walks of two to four kilometres lead to shaded swimming holes and granite slabs perfect for picnics. Longer options connect with the Cotter River Trail or climb toward Mount Ginini for sweeping views over the catchment. Birdwatchers often spot wedge-tailed eagles, crimson rosellas and the occasional platypus in deeper pools.
Clear, cold water invites a dip on warm days, though currents can be swift after rain. Native fish such as the Macquarie perch inhabit the lower sections; catch-and-release fishing is permitted in designated zones. Always check current water levels and park alerts before entering the creek.
From Canberra, drive south on the Tuggeranong Parkway then follow the Cotter Road and Brindabella Road. Turn onto the unsealed Jacks Creek Fire Trail, suitable for two-wheel-drive vehicles in dry weather. The final approach may require high clearance after heavy rain. No public transport reaches the trailhead.
Spring and autumn provide the most comfortable temperatures and reliable water flow. Summer can bring bushfire risk and sudden thunderstorms, while winter brings frost and occasional snow at higher elevations. Avoid the creek after prolonged rain when tracks become boggy and water levels rise quickly.
Continue downstream to the Cotter Dam picnic area or head west to the historic Brindabella Valley homesteads. The Mount Franklin ski trails and the Australian Alps Walking Track offer further day-trip options within the same national park.
