East Walk and Cowan Track is a 13.4km, grade 4 Circuit hike located in Lerderderg State Park Victoria. The hike should take approximately 4hrs to complete.


The East Walk and Cowan Track hike follows the Lerderderg River downstream from O’Briens Crossing through to Mine Camp. The trail, which initially hugs the Lerderderg River is rough and narrow in places and subject to flood damage.

The return part of the circuit via Cowan Track is steep and climbs more than 200 metres from the river to O’Briens Road. Return along O’Briens Road and Short Cut Track to O’Briens Crossing.

About the region

The Lerderderg State Park (incorporating the former Pyrete State Forest) is a 14,250 hectare park located between Bacchus Marsh and Blackwood, an hour’s drive from Melbourne, Australia. There are several maintained tracks for walking through the park and camping is allowed.

The park is named for the Lerderderg River which has cut the 300 metre deep Lerderderg Gorge through sandstone and slate, almost bisecting the park.

Getting there

O’Briens Crossing is located in the centre of the northern section of the park, along O’Briens Road. The crossing is located approximately 4km from the Greendale-Blackwood Road, with the turnoff approximately a 5km drive north of Greendale. The track into the crossing is quite good with sufficient access for 2WD’s and caravans.


  • Hiking Poles recommended for the Cowan Track part of the trail.
  • Do not attempt this hike following heavy rains as the river is subject to flooding.
  • Allow 4-5 hours depending on your level of fitness.

    1. Hey Tracey. There aren’t really a lot that are easy to navigate there. The east walk and a few from O’Brien’s crossing are the easiest and there is a good trail from the crossing to Blackwood. The ones on the western side of the park are all challenging and from the south there is a short walk to grahams dam which is easy and then a good circuit into the lerderderg weir or links 1 and 2 tracks.
