Mount Bingar is one of the highest peaks in the Cocoparra National Park and is home to one of the nicest views around the place.
I've been coming up here to admire the views for quite some time and feel the place could use a geocache.
It's also home to multiple radio antennae and transmission towers, all fenced off. You don't need to go anywhere near the fences or buildings to claim this cache.
I would also heartily recommend not driving any further up the track than the end of the bitumen. You can walk up to the trig point if you would like to look at the views in that direction, however, my little car didn't like coming back down the rocks.
You will need to climb a little way for this cache, though, and it's easily seen from exactly the right angle. You will also have no problems with mobile phone reception here.
