Went once ages ago, but the found this campsite again on a recent trip with fellow 4x4 earth'ers.

This a a simply stunning campsite. Head all the way out to the end of mini-mini forest road (the turnoff from Jenolan Caves road is marked).

There is some light 4x4ing to do at the end of the road.

If you have the Hampton NSW Topo 1:25,000 map it is marked as Gibraltar Rocks.
From the campsite, there is a great viewing rock if you walk down to it. You can also walk further along the road to the end and keep following the ridgline to the Gibraltar Rocsk and another great lookut over the Megalong Valley.
