I would like to do some exploration of the engineers track and Wentworth Cave. I have found some reports (including on this website) of routes to Wentworth Cave via Faulconbridge Point. But when I look at the topo, I can see what appears to be a firetrail with no locked gate along Patersons Range, and then a couple of tracks that seem to end close to the Grose, at points that look to be passable (at least - there are no cliff lines on the topo)
Can anyone advise if this is a viable route ? And how far along the Paterson Range could a 2WD get?
