Continue straight: From the ridge line, this walk follows the GNW arrow east downhill, initially keeping the 'Stop! Look! Listen! and Smell!' information sign[57] on your right. The track bends left and follows the timber steps[58] as the track winds steeply down the side of the hill. Near the bottom of the hill, the track passes a 'Rock n Roll' information sign[59] then comes to a long, metal footbridge[60]. The walk crosses the bridge over Calna Creek and comes to a signposted intersection, with a 'Fragile Marsh' information sign[61]

Continue straight: From the intersection, the walk follows the wide trail gently downhill as it bends right[94], keeping the valley to your left. After about 140m, the trail narrows a bit, leading down a few short but steeper sections[95] to an intersection (with some steps[96] on your left), where a 'The Great North Walk' sign[97] points back up along the trail.
(5km) Int of Great North Walk and Berkeley Close service trail → Berowra Waters trackhead
Turn left : From the intersection, this walk follows the GNW arrow post north-west down the sandy track[112], directly towards the valley. The track soon becomes rocky[113] and leads fairly steeply down the hill for about 150m before mostly flattening out and coming close to the top of an unfenced cliff with good views over Berowra Creek[114]. Here the rocky track continues more gently down along the top of the ridge[115] for about 200m and comes to a large rock platform[116]. This walk veers right to lead down the gap in the rock[117][118], climbing down some steel pegs[119] to where the track flattens out again[120]. The track leads across the saddle[121] for about 60m then veers left and follows along the base of a long rock wall[122] (on your right). Here the track leads down around the side of the ridge for just over 400m, passing some unfenced views for rock platforms[123][124][125] then down some sandstone steps[126] to find a tall sandstone overhang[127] with a timber seat[128]. From this cave, this walk continues along the base of the rock wall[129], and soon bends left and winds fairly steeply down a series of rock[130] and timber steps[131] to come to the edge of Berowra Creek (where there is a 'no wash' sign[132][133] facing the water from the rock platform). The track leads along the shore line for a short time to head onto the rock platform[134][135] in Washtub Gully.
Continue straight: From Washtub Gully[136], this walk crosses the creek[137] and follows the track, keeping Berowra Creek not far to your left[138]. After about 50m, the track passes an old partially sunken boat[139], then about 100m further on, the track passes a view point that is an obviously popular (but not recommended) jumping spot[140]. The track then soon leads up some steps and over a rise[141] behind the 'Berowra Waters Garden House' restaurant[142], then heads down the steps[143] to come to the signposted 'Berowra Waters Trackhead'[144][145] on 'Berowra Waters Rd'[146].

(7km) End of Kirkpatrick Way → Deep Bay Creek crossing
Veer right: From the seat and view[164], this walk follows the 'Cowan' sign[165] steeply uphill, following the series of timber[166] and rock steps[167]. After about 50m, the track leads up beside a rock wall[168], and at the top, turns right and mostly flattens out[169] for about 80m before starting to climb again[170]. At the top of this hill, this walk comes to a small clearing[171] (on the left, that has been used as a campsite[172]) and a large unfenced rock platform with great views[173] back over the valley (on your right).
Continue straight: From the view at the top of the ridge, this walk follows GNW arrow post[174] east, directly away from the Berowra Water views and over the small rise. The track soon leads down off a rock[175], where the track bends right and starts to lead fairly gently downhill[176]. The track then leads down a few short, steep, rocky sections[177] before crossing a lovely creek[178], flowing over the sandstone rock platform[179][180]. This creek may be slippery and can be particularly risky to cross after rain.

Continue straight: From the intersection[210], this walk follows the GNW arrow post[211] east along the track as it leads very gently downhill along the top of the ridge. Over the next 300m, the track passes a rock platform[212] and comes to a second rock platform with more views[213] and a 'Great North Walk' log book box[214] on a post. After leaving your note (and reading through a few entries), this walk continues down along the top of the ridge for another 200m to step down off another rock platform[215] (ignoring the track to your left). Here the walk starts to head downhill for the next 1km - initially the track leads down a series of short rocky steep sections[216][217], and passes some interesting large rock boulders[218][219] along the way. As the track moves further into the valley, it becomes consistently steeper[220] until leading down leading into the ferns and beside Joe Crafts Creek[221][222].

(12km) Valley viewing area → Int of GNW and Pacific Highway service trail
Continue straight: From the intersection, this walk follows the 'Cowan' sign[251] away from the dirt road and down along the rocky and sandy track. The track winds through the forest (with some interesting twisted, thin scribbly gums[252][253]) for about 600m before bending left and following under a set of power lines[254]. Near the Pacific Hwy (up to your right), this walk continues for about 150m and crosses over a very short section of timber boardwalk[255] before climbing up a few steps to a T-intersection with a wide management trail[256].

(14km) Freeway Bridge → Jerusalem Bay
Continue straight: From the intersection, this walk heads downhill along the rocky track[285][286]. The track leads past a few rock walls[287] over about 350m, then turns right onto, then steps down off, a long thin rock platform[288]. The track continues down along the side of the valley for another 200m, passing into a much more lush and dense forest[289], where the track then crosses the creek at a large rock platform[290]. On the other side of the creek, the track leads right down along the other side of the valley[291], passing a few small sandstone overhangs[292][293] then a particularly broad angophora tree[294] after about 500m. Soon after this angophora, the track leads down some rock steps[296] then begins to widen for about 300m, and passes a small track (on your right) marked with a 'No Camping or fires allowed' sign[297]. By this point, the broad waters (or mud flats, depending on the tide) of Cowan Creek are obvious[298], on your right. The walk now continues along the generally broad and flat track[299] for another 500m, then climbs up a set of concrete steps[300], marked with a GNW arrow post. At the top of these steps is a large, fairly flat clearing[301] with a 'No Camping' and a 'Great North Walk' sign[302] and a great view up the middle of Jerusalem Bay[303].

Continue straight: From the intersection, this walk follows the 'Great North Walk' sign[371] along the wide management trail as it initially leads over a small rise[372] then heads downhill, keeping the valley to your right. After about 300m, the trail turns sharp right at the T-intersection with another wide trail[373]. This flat wide trail[374] follows the power lines for about 250m to then veer left (at the Y-intersection[375]), heading downhill away from the power lines. The trail leads downhill for just shy of 300m, passing the speed hump signs[376] to then bend right at the large clearing[377] (ignoring the fenced trail[378] on your left). Then about 100m later, this walk ignores another fenced trail[379] (on your left) as this trail is still bending right. Here the trail heads around the side of the hill for 400m to come to an intersection with a track[380] (on your left, leading a few meters to the signposted campsite[381]) marked with a GNW arrow post[382].
Small Campsite Brooklyn Dam

(24km) NW Brooklyn Dam Campsite intersection → NE Brooklyn Dam Campsite
Continue straight: From the intersection, this walk follows the GNW arrow post along the wide trail, keeping the dam to your left. (This section of trail leads around to the far side of the dam.) After just over 250m, the trail crosses a small creek (at the apex of the dam) then continues bending left. The track passes some old concrete pipes[396] (on your left) then after about 400m, the trail comes to an intersection with a clearing and dam wall (to your left).
