This walk starts at a small isolated train station, and takes in some great scenery on the way to Woy Woy station. The walk gets most of the climbing out of the way quickly. Once up on the main ridge there are great views along the Hawkesbury River and Mooney Mooney creek. Highlights of the walk include Kariong Brook Falls and Mt Wondabyne, the highest point in the area. The walk does pass Woy Woy tip, and has a bit of a road slog at the end, but overall is a lovely one way walk.

Wondabyne is situated in Brisbane Waters National Park on the banks of Mullet River, which feeds into the Hawkesbury River north of Brooklyn. The area is defined by the National Park's flora and fauna, the quarry, railway station and a few houses sitting above the water around the river. The quarry produced sandstone building materials, used in the construction of the National War Memorial in Canberra. More recently, in 2000, the quarry was re-opened for restoration of St Mary's Cathedral spire in Sydney. Wondabyne Station, named after the nearby Mt Wondabyne, was built in 1889 and exclusively used for the quarry - it was then known as Mullet Creek Station. The station is one of the smallest on the line and one of very few railway stations in a NSW National Park. When you catch the train to Wondabyne, let the guard know you want to get off at Wondabyne Station, otherwise the train will not stop. Travel in the last carriage as the platform is very short. To catch the train from Wondabyne, wave to the driver.

From the north-bound platform of Wondabyne Station, this walk follows the 'The Great North Walk' sign[1] off the southern the end of the platform[2], keeping the train lines (and water) to your left. The track soon leads past a strangler fig[3] and a large boulder[4] then bends right and heads up a timber staircase[5] with a metal landing at the top. The track winds steeply uphill, up a series of timber[6] and rock steps[7] for just over 200m to pass a filtered view of the cranes[8] (right), down at the old Gosford Quarry. Here the walk continues a bit more steeply uphill for another 150m, up a series of rock steps[9], and then, soon after passing up the carved steps in a cleft in a rock[10], the track flattens out[11] and comes to a clearing at the end of a management trail[12], marked with a 'Brisbane Water National Park' sign[13]. Continue straight: From the clearing[14], this walk follows the wide management trail uphill past the 'Brisbane Water National Park' sign[15]. The trail leads up quite steeply[16] for about 250m, where the trail bends right then leads gently uphill[17] for about 600m. Here the trail leads up a short but quite steep hill[18], to then bend left and, about 150m later, come to an intersection with the Pindar Cave track (that leads over a rock platform[19], on your left), marked with a GNW arrow post[20] (on your right).

Turn right: From the intersection, this walk follows the 'Patonga' sign[24] heading east down along the rocky track[25]. The track soon bends right and heads around a rock outcrop[26] then continues down through the heath and scribbly gums[27] for about 400m to come to a flat rock platform[28]. Here the track continues downhill over several more rock platforms, becoming progressively steeper[29] for just over 1km to head into the cool valley and come to the bank beside Myron Brook[30]. Continue straight: From the western side of Myron Brook, this walk crosses the creek on the sandstone rock platform[31] to follow the track up a few stone steps and up the short steep hill[32]. The track then flattens out as it leads around the side of the hill for about 200m to pass alongside a long rock wall[33] (on your left). Now leading downhill, the track continues for another 100m then heads down a short steep section[34] into the dense moist gully, coming to a faint intersection in front of Kariong Brook Falls[35] (on your left) (just before crossing the creek, which is often underground).
Kariong Brook Falls
Alt = 27 m
This tranquil spot of the Great North Walk is home to some lovely falls and a water hole. The eastern side of the creek has a tall sandstone cave and wall. After rain these falls can become very spectacular, other times is a cool place to rest. A great spot to stop for a snack.

The track leads under the overhang[39] and then winds up the rocky path for about 400m, past a few rock walls[40] and among the grass trees[41]. The walk then heads up some more stone steps, bending left on the steps with a metal handrail[42]. The rocky track continues up for another 130m over a few more rocks[43] to come to a flat clearing[44] (on your right, that has been used as a campsite). From the clearing, the track continues uphill, passing another rocky outcrop[45] after about 60m, then after about 80m more, the track leads to a T-intersection[46] with a management trail (and a sign pointing back to 'Girrakool'[47]).

Veer right: From the intersection, this walk follows the GNW arrow post and 'Patonga' sign[54] east, gently downhill along the narrow track. After about 250m, the track leads to a notably large rock platform[55] with a clear view across the valley to Mt Wondabyne[56]. Here the track continues gently downhill, crossing more rock platforms[57] for about 300m to head over a section of timber boardwalk[58] and past a few disused power poles[59]. The track then continues over another rock platform for another 200m to cross a small ephemeral creek[60]. From the creek, the track leads up a short distance up under the power lines to come to a T-intersection[61] with a wide trail, where a sign points back to 'Girrakool'[62]. Turn right: From the intersection, the track follows the GNW arrow post along the management trail[63], initially keeping the power lines to your right. The trail soon bends left and leads uphill. As the trail flattens out again, it comes to a three-way intersection marked with a 'Great North Walk' and 'Wondabyne Station' sign[64], pointing back along the trail. Turn left: From the intersection, this walk follows the 'Mt Wondabyne' sign[65] south up the trail. The trail soon begins to narrow[66] and after almost 200m, the track steps up to cross a rock platform[67], following a few GNW arrow posts to find a GNW 'Walker Register' tube[68]. After writing a comment, the walk continues uphill[69] along the track for about 700m, as the track become progressively flatter[70], passing beside the Mt Wondabyne Peak (up to your left). Then about 50m after leaving the trees and entering a section of low heath, this track then comes to a three-way intersection[71] (the Mt Wondabyne peak track, on the left[72]), marked with a GNW arrow post.

The track is leads gently at first then starts to climb up a series of rock ledges[73]. After about 60m, the track passes a small cave[74] (large enough for 2 or 3 people to lie in). The track then continues to climb for another 90m, up the rocky track then for through a grove of small trees[75], to come to the first peak[76]. The faint track continues along the ridge for another 60m then comes to the main peak, where there is an old trig station[77] and great panoramic views[78]. (Retrace your steps back to the main track, then turn left to continue along this walk.)
Mt Wondabyne
Alt = 230 m
Mount Wondabyne is one of the most prominent peaks in Brisbane Water National Park. The long cone-shaped hill has a rocky top and is home to a trig station. Walkers can enjoy full 360-degree panoramic views from the top. To the east are good views over the Brisbane Water, Woy Woy and other central coast suburbs. West, down next to Mullet Creek, you can see some buildings near Wondabyne Station and the train line. Otherwise, most of the expansive views are over much of Brisbane Water National Park. There are some small trees providing limited shade, a great place to soak up the views.

I met scouts who walk here regularily and they said they use a GPS because of the myriad side tracks
Still the impromptu camping out was great

IP:129.78.32.xxx | 2011-11-04 05:35:26
Not sure what the 'labyrinth' comment is about. The track notes are precise, accurate and just about infallible. There are a number of tracks in the area, but you can't go wrong following these notes. Take a GPS for extra navigational fun, but it's not essential. The walk's end is a bit of a downer (tip and long street/road slog), but it's pretty magnificent before then. Thanks for the excellent instructions, WildWalks!

CAC - 2011-11-07 Woy Woy to Wondabyn
IP:203.206.233.xxx | 2011-11-07 13:26:56
Walked this in the opposite direction to make sure I made it to the landfill gates before they closed, which turned out to be completely moot as there's 24-hour signposted pedestrian access through both gates (worth adding to the track notes, I think). Navigation was no problem; in this direction you just walk up the unpleasant shadeless road forever and once in the bush follow the GNW/Girrakool/Wondabyne signs. Took 4.5 hours walking at a normal pace.

Hi CAC
Thanks for you feedback over the past few days, greatly appreciated. Did you happen to snap a photo of the 24hr pedestrian access at the lower gate?? When I walked it there was obviously some people had climbed the embankment, but no formal hole for pedestrians (like at the upper gate).
Matt :)

Hi Matt, sorry for the delay, wasn't expecting a reply. I didn't take a photo, but as I remember there was a formal pedestrian gap left in the fence near to where people'd climbed the embankment, and the right hand sign said pedestrian access was allowed. Or maybe it was a heat-induced mirage? :) Anyway, cheers and thanks for running this site!
