I was walking at Coolah Tops today, looking for the lava cave. I found the track down from pinnacle lookout OK, and just below the ridge top there was a sign saying the cave was 1.6 km along a rough unformed track. No problems so far. I followed the route down the steep slope then it reversed direction along the base of the cliff line. Passed a few small caves as the route made its way along the cliffs ans the valley narrowed. After an hour of scrambling I was almost at the end of the valley but had not seen any large caves at all. At this point the route seemed to peter out and I could not see any way forward, so I returned with my mission unaccomplished.
Did I take a wrong turn somewhere or should I have pressed on and searched for a route?
