I'm planning a loop walk starting from Barren Ground carpark, off Flying Fox Pass, bashing downstreams along Brogers Creek (which I've already done), then get across some private land until reaching the start of Drawring Room Rock track, up to the rock, then off the saddle and link off Kangaroo Ridge Trail back to Barren Grounds. Full length is about 23 - 25km.
The only section I'm not sure is in the blue shaded circle, which are all private farms. There is a road, but I don't know if that's private or public. Have anyone ever walked across the area? Maybe stick to the Brogers creekbed is safter? Dealing with people is far more troublesome than dealing with nature.
