Hike overview
The Old Noarlunga Circuit provides a challenging 3.5 kilometre loop hike for experienced walkers (grade 4) within Onkaparinga River National Park, South Australia. This trail offers a taste of the Gorge Trek, incorporating a single rock scramble and sections of narrow walking track. The route ascends a hill alongside a pipeline before a steeper descent back to the Onkaparinga River.
Careful navigation is required at Old Coach Track near Gate 30, as the continuation of the walking trail is easy to miss. Look out for the path branching left after the second stobie pole. If you do miss the turn, you can continue along Old Coach Track until rejoining the river and retrace your steps from there.
A pedestrian bridge across the Onkaparinga River in Old Noarlunga now provides a convenient starting point for this hike.
