Where were you planning on camping?
We've only been the once for a poke around so have vague memories that there wasn't any nice place there.
One the way in along Meryla Road, there was a bare triangle right at a right fork to a property, then after you come back and go along Meryla fire Trail road, there was one nice spot with space for one on the left and one on the right. I don't remember anything else.
We ended up going first to Bundannon(small tent only & $$$), then to the Forest HQ camp in Wingello Forst (free). Very nice spot if you like pines. Nice long drop and wood stoves(take own), except no wood fires weekend we were there. I'd suggest keeping it in mind if you don't find something nice in Meryla.
Our apologies but The Boss has shelled out for some course that weekend, so I can't even register a tyre kick.
Enjoy yourselves.
