I called into here today on the way past. "Castle Rock" camp ground where we decided to go is way better than the other one. More level and larger. The other one is more bush camping for tents.
So "Castle Rock" is 8km in from the turnoff off the New England Highway on the right, past the first campground. 6km past Ballandeen. I will draw a mud map to where abouts I think is the better spots but really, I wouldn't care where we get. With it being a busy time of year, all we can do is try and save spots for everyone to be around the same area.
Looks like there are 40 places left for Fri/Sat and 52 for Sun. Plenty more for the other days.
I will draw a mud map up now and post it so you understand the way the grounds are layed out. I will post that soon.
