This walk follows a wide concrete trail through Berowra Valley National Park, through lovely bushland and the site of the historic Zig Zag railway. The railway is long gone, but the quarry site is interesting to explore and crossing Zig Zag Creek on the bridge gives a lovely view down on the fern trees. Stop and read the information signs along the way, bring your dog for a walk or use this trail for fitness training. The trail on the north side of Zig Zag Creek is very steep for about 50m, otherwise, this walk is easy to follow. To save the car shuttle you can just allow extra time and retrace your steps back to the start. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
