The trail leads down across a usually small creek[4], then heads up to the well-signposted intersection[5] beside the Jungo campsite[6][7], where a 'Fishponds' sign[8] points back down along the trail.
The Jungo
Alt = 98 m
The Jungo is a relatively small clearing and campsite near the junction of Berowra and ZigZag Creeks at a well signposted intersection[9]. There is often water in the creeks (treat well before drinking) but there are no facilities[10]. Speculation on the source of the name 'Jungo' includes the Aussie tendency to abbreviate words ('Junction' gets corrupted to 'jung-o' etc) as well as a possible derivation from one of a few similar sounding aboriginal words.

The bridge path now merges back to the main wide trail[19] and heads steeply uphill[20] for about 50m[fac=8401] (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][fac=8402]. (Retrace your steps back to the main track, then continue straight to continue along this walk.)
Thornleigh zigzag railway
Alt = 120 m
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
Old Thornleigh Quarry
Alt = 129 m
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 amphitheatre[fac=8402] making 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
