Razorback and Ah Kow Spurs is a 13.5km, grade 4 Circuit hike located in Lerderderg State Park Victoria. The hike should take approximately 6hrs to complete.


Razorback and Ah Kow Spurs represents a remote gorge walk along the Lerderderg River. It’s a demanding walk into one of the more remote areas of the Lerderderg Gorge. There is considerable evidence of gold mining operations in the form of diggings, water races and dry stone walls. Razorback Track’s decent into the gorge is along one of the easiest and most enjoyable spurs in the park.

HOWEVER, the Aw Kow Spur is one of the parks steepest and most tiring climbs!

Getting there

From Melbourne, follow the Western Freeway 9km past Bacchus Marsh and take the Myrniong exit. Continue along the Myrniog-Greendale Road for 1km, then turn right on the Mt Blackwood Road. Follow this narrow surfaced road north for 10km to pull into a turnoff on the right at Square Bottle Track (just 250m past Shuter Track). Park near the gate overlooking a small dam.

Suggested items to pack

Day Pack with picnic lunch and at least 2 litres of water.


A section of this hike (at least a 2.5 kilometres) follows the Lerderderg River. You may need to cross several times to find the best path so poles and water shoes will benefit if you have them. Wading may also be required.
