Hornsby Shire residents can join a guided 5 km bushwalk along the Blue Gum track, taking about three and a half hours. This moderately challenging trail features diverse vegetation and offers views of the Hornsby Quarry development site.

Rated grade 3.5, the walk suits adults and older teens (16-19) with prior bushwalking experience. Children under 16 must be accompanied by an adult, as the trail includes steep sections and a tricky creek crossing.
