Turn right: From the intersection, this walk follows the ‘Great North Walk’ sign[42] down the narrower track. The track leads downhill for about 70m, getting steeper[43] as it goes, and then crosses Berowra Creek[44] – this creek may become impassable after rain. On the other side, the walk comes to an intersection on a small sandy beach. Here, the walk turns left, following the GNW arrows downstream for about 250m among the grass trees and crossing a flat timber bridge[45]. The rocky track then continues for just shy of 250m and crosses a mossy gully on a large flat rock[46]. The track then continues, staying fairly flat[47] for another 170m before bending right and heading steeply uphill[48]. At the top of this climb, the track soon leads to a section of fenced cliff[49]. At the end of the fence, the walk passes through casuarina forest[50] for a short distance before passing alongside another (longer) fenced cliff and coming to the Elouera Lookout[51], where there is an intersection with the ‘Westleigh’ track[52] (on your right).

Turn left: From the intersection, this walk follows the management trail uphill[70]. The trail soon bends right and after about 90m (ignoring side tracks), the walk heads around a locked gate[71]. Here the walk follows the grassy (and rocky) trail between two houses[72] to an intersection with Quarter Sessions Rd[73] (between 394 & 396).
Turn left : From the intersection, this walk follows Quarter Sessions Road uphill. The road passes over the rise and, after 130m, comes to a point where the road bends right[74], just beside a ‘Berowra Valley Regional Park’ sign[75] (on your left).
Turn left: From beside 280 Quarter Sessions Road (Westleigh)[76], this walk heads towards the ‘Berowra Valley Regional Park’ sign[77], over the grass towards the timber platform[78]. The walk steps onto the timber platform (with a handrail[79]) to find a filtered valley view[80] (to your right) and the engravings[81] in the sandstone (to your left). At the end of this side trip, retrace your steps back to the main walk then Turn right.

Veer right: From the cave, this walk follows the ‘Galston Gorge’ sign[118] up the track and timbers steps. Soon the track turns left and follows a Great North Walk arrow up the hill[119], at the red and white ‘Danger’ sign[120](ignoring the other track). The track climbs up the carved steps[121] onto the rock platform and continues up the rocky track until just after passing through a narrow gap between two rocks[122], where this walk comes to the un-signposted (and faint) intersection with the Pogson’s Trig track (on the left).
Continue straight: From the intersection, this walk heads down along the side of the hill[123], whilst keeping the main valley to your right. The track leads down some rocky steps, passing just above a rock platform (a short distance down on your right, with a plaque dedicated to ‘Cora’[124]). The track then leads down along the base of a cliff, passing under a rock overhang[125]. The track continues along the base of the cliff for another 50m then starts to wind downhill (with some handrails[126]) to come to a rock platform beside the creek[127]. This walk then crosses Berowra Creek on the flat timber bridge[128]. At the end of this side trip, retrace your steps back to the main walk then Turn left.
