This walk follows the Sphinx and Warrimoo Tracks along scenic Cowan Creek to Bobbin Head, and then returns via the Bobbin Head Track along the ridge to the park entrance.


The start of the walk is at the Sphinx, near the end of Bobbin Head Rd in Turramurra, just before the road enters Ku-ring-gai Chase National Park. If you are using public transport, catch the bus from Turramurra Station to the Sphinx. The buses are relatively infrequent so check timetables.

Track notes

From 25 Feb 2007, last checked 25 Feb 2007

From the park entrance at the top of the Bobbin Head Rd, take the road to the right down to the Sphinx. Follow the sealed track from the Sphinx for about 30m, and turn right at the T-intersection. Turn left shortly after, following the Sphinx/Warrimoo Track sign down steeply down to a small creek. The track follows the small creek down to Cowan Creek, passing a number of twisted old Angophora costata (Smooth-Barked Apple) along the way. At the bottom turn left, and follow the well-formed track along Cowan Creek. The track winds in and out of a few bays along the way. It also passes an old aboriginal midden where a large cave overhangs the water. After about 3.5km along the creek you pass a sign to the Bobbin Head track.

If you have time, press on for 200m onto a sealed track behind the back of the marina and cross the bridge to Bobbin Head picnic area, a nice spot for a break. By wandering to the end of the car park you can follow the Gibberagong Track for about 10 minutes to visit some aboriginal engravings and rock art. Return back to the signposted track past the marina and climb up on to Bobbin Head Ridge.

After a steep climb for the first kilometre, including some switchbacks, the ridge flattens out and it is easy walking along a fire trail back to the park entrance.
