This spot is 33 Km along a so-so gravel road (probably impassable when wet) off the Barrier Highway, west of Cobar, with not much to see on the way. You could be excused for turning back to the highway. But even without the aboriginal paintings, it is an unexpectedly pleasant spot to spent an hour or two.
Recommendation: Walk slowly, look at the details, savour the atmosphere, imagine the life of the original inhabitants, then of the first discoverers. Speak quietly, take your time with your photography here. And don't hurry on the road, either.
The geotags here are a bit rough, because the landmarks we saw are not visible in the satellite pictures. At the end of the road there are shelters and toilets and a gate stopping cars going up the hill to an older turning circle just visible in the satellite picture. There are more shelters and toilets (not visible). Then there is a walking track up and over a low ridge to a more level grassy area. The caves with the paintings are on the west side of this area and a small creek runs south on the east side. It's possible that I've got things wrong and located everything too close to the road.
