This enjoyable walk starts from where the old Pacific Hwy where you walk along dirt roads and trails for while alongside the wide Mooney Mooney Creek, and under the huge F3 Mooney Mooney bridge. The wide track continues upstream, passing a few campsites before crossing the wide creek at a pleasant large rock platform. Not too long after crossing the creek you will pass the lower Mooney Mooney Dam where the old trail leads you uphill past another campsite, a quarry to the Somersby Reservoir. The track then leads past some rural properties and across the delightful Robinson Creek among the Gymea Lilies before finishing with a section of road walking to the Somersby Store.

Length = 321 m
Time = 7 mins
Climb = 12 m
Descent = -25 m
From the intersection, this walk follows the 'Newcastle' sign along the narrowing gravel verge, keeping the Old Pacific Hwy just to your right. After about 200m, this walk comes to then crosses the concrete road bridge over Mooney Mooney Creek, enjoying the view of the wide creek below. Once on the other side, this walk heads past a detailed 'Risk Warning' sign suggesting you be sensible as you cross the bridge (hope it is not too late) to then come to an intersection with Karool Rd, just on the other side of the highway (on your right).
Old Pacific Highway Mooney Mooney Creek Bridge
Alt = 2 m
The Sydney-Hawkesbury stretch of the Pacific Highway was built in the 1920s, replacing a route that had existed since the 1830s. The original Peats Ferry Road was cut by a settler named George Peat, making a track to his property on the banks of the Hawkesbury River.
This road became the 'Old Pacific Highway' upon the opening of the F3, or Sydney-Newcastle Freeway, in the 1980s. This bridge is the smaller of two crossing Mooney Mooney Creek - the other, Mooney Mooney Bridge, is part of the F3 freeway and is the highest road bridge in Australia.

Continue straight: From the end of the dirt road (that branches of Karool Rd, just north of the Mooney Mooney Bridge), this walk heads uphill along the trail and around the locked gate next to the timber 'Brisbane Water National Park' sign. The trail leads uphill for about 200m to where the trail bends left to pass over the crest of the hill (passing a faint track on your left). Here the trail leads down the other side, still keeping Mooney Mooney Creek to your right for another 400m to come to an intersection marked with a GNW arrow post, beside a large grassy clearing and campsite (on your right).
Mooney Mooney Creek Campsite (south)
Alt = 4 m
This is clearing is beside the wide Mooney Mooney Creek and provides a large flat area to pitch a few tents. There are some high tension power lines nearby and you can hear the hum of the F3 from here, so it is not the most remote campsite. There are no facilities or water (the creek is salty). All that said it is still a pleasant spot beside the wide creek to rest for a while or for the night.
Mooney Mooney Creek Campsite (south)

Veer right: From the intersection just above the campsite, this walk follows the GNW arrow post down along the track, keeping the clearing and campsite to the right. The track soon leads over a small flat timber bridge then over the next 60m, the track heads under the high tension power lines (past the caution sign) and then along a short section of timber boardwalk. About 20m later, this walk veers right at a Y-intersection, then continues along the mostly flat track beside Mooney Mooney Creek for about 300m, to cross a small rocky tidal creek. The track then continues through the tall forest beside Mooney Mooney Creek for about 600m, passing a couple of she-oak stands before the track then bends left and comes to an indistinct intersection beside a timber and metal footbridge. Continue straight: From the intersection, this walk cross the timber and metal footbridge over a tidal, unnamed creek to then turn right and follow the track which soon bends left. Keeping Mooney Mooney Creek to the right, this track passes a small cliff then follows the mostly flat track through the tall forest for about 170m to come to a large clearing with tall blue gums and a metal fireplace (on your left), signposted as a 'Camping area'.
Mooney Mooney Creek Campsite (north)
Alt = 7 m
This signposted campsite is sits among the tall eucalypt and bracken fern forest beside the Mooney Mooney Creek. This is a very pleasant flat clearing to spend a night, there is a small metal fireplace hotplate and room for a small number of tents. There is No drinking water or other facilities at this campsite (Mooney Mooney Creek is salty at this point, treatable water may be found about 2km north).

Continue straight: From the campsite, this walk follows the clear track north, keeping the wide Mooney Mooney Creek to your right. The clear, wide and mostly flat track leads alongside the creek for about 1.2km to come to the southern bank of Ausburn Creek (about 130m past a rock wall, on your left), a few metres above its confluence with Mooney Mooney Creek Continue straight: From the south bank of Ausburn Creek, this walk crosses the narrow rock platform and creek, then follows the track fairly steeply uphill for about 200m. At the top of this climb, the track gently undulates alongside Mooney Mooney Creek for about 700m before heading down to find a large rock platform on the western bank of Mooney Mooney Creek. This large rock platform is a natural ford of the perennial Mooney Mooney Creek and is home to a scattering of small and large waterholes.

This creek may become impassable after heavy or prolonged rain. Here the walk turns left and follows the rocky track that leads gently up alongside the creek through the pleasant forest. After a little over 1km, the walk comes into view of the tailwater of the dam and then past a fenced cutting (on your right), the site of an old pump house. About 60m past this fenced area, the walk leads up along the now widening track to find the edge of the fenced lower Mooney Mooney Dam wall.
Lower Mooney Dam
Alt = 40 m
Lower Mooney Dam is located on the Mooney Mooney Creek, about 21 km upstream from the Hawkesbury River. In March 1938 the Gosford Mayor turned the tap to add the water from this dam into the small town water supply of the time. It is a concrete arch dam, with a capacity of 1,000 megalitres, and was superseded by the more than 4 times larger 'Upper Mooney Dam' in 1982. There is a set of timber steps and a faint track that leads down to the waters edge on the uphill side of the dam wall, the dam wall is fenced and is clearly out of bounds. A sign reminds visitors that swimming is not allowed.

The track leads into the bush among gymea lilies (Doryanthes excelsa) and eucalypts for almost 300m, crossing a couple of short flat timber bridges to then head along a few sections of timber board walk through a weedy section of bush. The track then continues gently downhill for another 150m to cross over a trail. Following the GNW arrow post, this track now begins to lead more steeply down for about 250m, passing through another large grove of gymea lilies, a small cave (on your left). The walk continues down the timber then stone steps to head into the dense moist forest and across a flat timber bridge, coming into view of the creek. Here the walk bends right and leads beside the creek for a short time before bending left, following the GNW arrow post across the creek flowing over the mossy rock bed. Just downstream is a small pool and cascade.
Here the walk starts to climb up the other side of the valley, soon crossing a small flat timber bridge. The track then winds steeply out of the ferny and densely forested valley, up a series of timber and stone steps for about 130m where another GNW arrow post marks the end of this section of steep climbing. This track now leads gently up among some tall eucalypts and past a large grove of gymea lily for about 230m to come to a T-intersection with a wide management trail. Veer right: From the intersection, this walk follows the GNW arrow post uphill along the wide sandy trail for about 40m to pass a faint trail (on your right).
