Hard track
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. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.

Old Pacific Highway Mooney Mooney Creek Bridge

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.

Mooney Mooney Creek Campsite (south)

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.

Lower Mooney Dam
Lower Mooney Dam

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 It is a concrete arch dam, with a capacity of 1,000 megalitres, and was superseded by the more than 4 times larger 'Upper Mooney Dam' in 1982.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.
