Newnes is good camping and hiking.
You need to be self contained.
A 4wd will get you over the river to better camping.
It is about 40 mins from Lithgow.
You can walk around the old shale oil site from the camp.
Walk up to the glow worm tunnels from camp or drive part of the way.
Also you can walk to Glen Davis on the Pipeline track.
Camping at Glen Davis not the one in town the NPWS area.
Boyd River camp ground is close to a lot of hiking, Kanangara walls, Jenolan Caves and Uni Rover trail to the Kowmung River (hiking).
Wiki Camps should be your friend.
I dont do caravan parks so I cant help you there.
Enjoy.
