De Burgs Bridge to Thornleigh station
(0km) Int. Opposite the end of Lady Game Drive → Int of GNW and Christie Park track
Turn right: From the intersection, this walk follows the 'The Great North Walk' sign[1] north, gently downhill along the management trail. After about 80m, this trail crosses a concrete bridge[2] over Rudder Creek (beside a concrete sewerage pipe[3]). From here, the trail leads uphill for just shy of 200m to come to an intersection with the GNW track (on your left), where a 'Lane Cove Weir' sign[4] points back down along the trail.
Turn left: From the intersection, this walk follows the 'Thornleigh Oval' sign[5] west, gently down the track, away from the management trail. The track almost immediately passes the large metal pipe (crossing the Lane Cove River[6]) then winds down the rocky track[7] for about 200m, through open eucalypt forest[8] with some limited views left over the valley, to come to a weedy section of track marked with a concrete sewerage access point[9]. Here the track mostly flattens out and leads along the side of the hill for about 400m to head down a few steps and cross Quarry Creek[10]. The walk then heads up some steps and follows the track for another 30m to come to a T-intersection[11] with the Gloucester Ave fire trail, marked with a GNW and NPWS arrow post[12].
Turn left: From the intersection, the walk follows the GNW arrow post[13] gently uphill along the management trail, away from the gate whilst keeping the power line poles on your left. After about 30m (just past the second power pole), this trail leads to an intersection with a track (on the left), marked with another set of NPWS & GNW arrow posts[14] (just under the high tension power lines[15]).
Turn left: From the intersection, this walk follows the GNW arrow post[16] south, downhill along the track and under the high tension power lines[17]. The track winds gently downhill for almost 150m until, just after passing close to the the high tension power line tower[18], this walk comes to a locked green shed[19] opposite a fenced-off pipe bridge[20] (down in the valley to your left).
Continue straight: From the green shed, this walk follows the track[21] along the side of the hill, keeping the valley to your left (running parallel with the high tension power lines, up to your right). After about 150m, this walk comes to an intersection with a faint track on your right (that leads a short distance to a management trail), marked with a GNW arrow post[22].
Continue straight: From the intersection, this walk follows the GNW arrow post along the mostly flat track, through the dense forest, and almost immediately passes a concrete sewerage access point[23]. After about 70m, this walk heads down a few timbers steps to cross a small gully[24], where the track continues for another 100m (passing close to a few houses[25]), then crosses two flat timber bridges[26] over Congham Creek. Here the walk veers left up onto the rock platform[27] and follows the track gently uphill for another 80m to come to a three-way intersection, marked with a GNW arrow post[28] (and a sign pointing left to 'Marsfield'[29]).
(2km) Int of GNW and Christie Park track → Int of the Great North Walk and the West Pymble service trail link track
Veer left: From the intersection, this walk follows the GNW arrow post[32] gently uphill along the side of the hill (keeping the valley to your left) for about 100m to come to a small clearing and three way intersection, marked with yet another GNW arrow post[33] and a pile of rocks[34] (on your left).
Turn left : From the intersection, this walk follows the GNW arrow post[35] up the short rocky hill[36] and away from the high tension power lines[37]. The track (rocky early on[38]) leads along the side of the hill among some grass trees[39] for about 300m before passing under the power lines again. Here the track continues for another 300m along the side of the valley to come to a clear intersection with intersection with a wide management trail[40].
(3km) Int of the GNW and the West Pymble service trail link track → Int of the GNW and the South Turramurra High School trail
Turn left : From the intersection, this walk follows the GNW arrow post, directly away from the face of the 'Lane Cove Valley' aluminum sign and map[45], down the track and timber steps[46] to a sandy beach on the Lane Cove River[47]. Here the walk turns right to cross the weir and bridge[48] over Avondale Creek, (this may become impassable after heavy or prolonged rain) then climb gently uphill for about 120m to come to a faint intersection with a faint track (on your left - this faint track leads down to another old weir).
Continue straight: From the intersection, this walk heads gently uphill following the main track, whilst keeping the valley to your left for about 30m to come to a clear Y-intersection marked with a GNW arrow post[49].
Veer left: From the intersection, this walk follows the GNW arrow post[50] along the track, keeping the Lane Cove River a short distance to your left[51]. After about 80m, the track steps up to and crosses a short section to timber boardwalk/bridge[52]. Here the walk climbs up the rocky hill following a series of concrete access points[53] and timber steps[54] for about 230m to come to a T-intersection with a management trail, marked with a GNW arrow post[55].
(3km) Int of the GNW and the Turramurra High School service trail → Int of GNW and Kissing Point Road path
Continue straight: From the intersection just below the Koombalah Ave gate, this walk follows the management trail gently downhill, whilst keeping the valley to your left. The trail initially leads over a rock platform, then about 50m later, leads down a steep hill[58]. The trail then heads gently down for about 400m before a short steep hill[59] leads down to a metal high tension power line tower[60]. Here the trail bends right and leads down and along the side of the hill for another 200m to pass another high tension power line tower[61] and head behind a few houses. Just behind the second house, this walk comes to ephemeral creek on a rock platform[62].
Continue straight: From here, this walk crosses the ephemeral creek[63] (keeping the houses up to your right) and continues along the trail for about 30m to come to a T-intersection with a wide, shared, concrete path, marked with several signposts[64].
(4km) Int of GNW and Kissing Point Road trail → Browns Waterhole int
Continue straight: From the intersection, the walk heads fairly steeply downhill along the concrete path. The path passes a few signs[70] over about 100m, then comes to an intersection with a track (on your left), marked with a timber barricade and a GNW arrow post[71].
Veer right: From the intersection, this follows the concrete path downhill for just shy of 50m to come to a intersection with a dirt management trail[72]. This intersection is beside the Lane Cove River crossing[73] (on your left) and is marked with a 'The Great North Walk' sign here[74].
Browns Waterhole
(4km) Browns Waterhole int → Int of GNW and the STEP track (east)
Veer left: From the intersection, this walk follows the GNW arrow post[82] downhill along the management trail for about 30m to cross a small culverted creek[83]. The walk then follows the trail up the short hill to come to an intersection with the signposted 'STEP track'[84][85] (on your right).
(5km) Int of GNW and the STEP track (east) → Int of GNW and the STEP track (west)
(6km) Int of GNW and the STEP track (west) → Int of GNW and the Pennant Hills Park track
Veer right: From the intersection, this walk follows the 'Thornleigh Station' sign[97] past the 'Lane Cove Valley' map, initially keeping the other trail and river to your left. The trail follows the valley floor, keeping the river just to your left, for a bit over 500m, to then cross the Lane Cove River at a rocky ford[98]. This crossing may become impassable after heavy or prolonged rain. On the other side of the river, this walk continues along the trail[99] for about 400m (with the river now close by on your right) to come to an intersection with a faint track[100] (on your left, that leads up towards Pennant Hills Park).
