Katoomba to Jenolan Caves

My partner and I are travelling in this area in April. We are keen to bush camp and have a swag so the more formalised camp grounds don't suit as much as being able to decide to stop and pitch.Canberra to Hill End, then down the Bridle Track then onto the Kanimbla Valley Area. I have heard there is a camp ground called Cox's River Camp Ground but cannot find reference or topo's indicating location. We would like to base for 3-5 days in the area around Kanimbla, Ganbenang or basically between Katoomba and Jenolan Caves. We have a 4wd and are obviously able to go offroad, but would like to know if anyone can give directions, or suggest a map that would show both Cox's River campground or Black Range Campground. If someone has any other ideas for another area between Katoomba and Jenolan Caves (don't want to go as far down as Megalong Valley) to bush camp then I'd appreciate the post.
