This walk follows a wide concrete trail through Berowra Valley Regional 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.

Thornleigh zigzag railway

Thornleigh zigzag railway
The Thornleigh zigzag railway originally ran from the main rail line near Thornleigh to a historic quarry, near present day De Saxe Cl, Thornleigh. There are only minor fragments still visible today. The 'Heritage Trail' in Thornleigh has interpretive signs for the railway and the old Thornleigh Quarry. A book is available with some detail on railway and associated quarry: 'Sydney's Forgotten Quarry Railways' by John Oakes, ISBN 0 9757870 3 9

The bridge path now merges back to the main wide trail[19] and heads steeply uphill[20] for about 50m(with a handrail on the left side[21]). The trail then mostly flattens out for about 50m and leads gently up to the front of the old 'Thornleigh Quarry'[22], marked with a plaque on a large stone[23][24][25].

Old Thornleigh Quarry

Old Thornleigh Quarry
The old Thornleigh Quarry[26] is located beside the Heritage Trail in Thornleigh, within Berowra Valley Regional Park. The quarry dates back to 1883 and was initially a source of 'ballast' for portions of the Sydney (Homebush) to Newcastle (Waratah) rail link. There is a firm, flat dirt track[27] that leads about 40m from the concrete trail to the centre of the old quarry[28]. You will find a series of log seats in this amphitheatremaking this a pleasant spot to sit and enjoy the intriguing mix of nature and history. A book is available with some detail on this quarry and the associated zigzag railway: 'Sydney's Forgotten Quarry Railways' by John Oakes, ISBN 0 9757870 3 9
