This short walk follows a concrete management trail between Bellamy St and De Saxe Close. This is one of a few dog friendly bushwalks in the Berowra Valley Regional Park. You walk through some beautiful bush with a good array of grass and eucalyptus trees. At the bottom of the valley a bridge spans ZigZag Creek allowing you to keep you feet dry. There are also some good information signs explaining the rich history of the railway line and quarry that once passed through here. The authorised dog walk exits up the steps to the base of De Saxe Cl. We have also include an alternate exit staying on the main trail to then end of Timbarra Rd for those walking without dogs.
