there is some nice creeks out bellingen way, called the promise land, to get out there you do need 33's minimun due to dick heads ripping the tracks up out there.
and a local to show you how to get out there, lots of little off tracks every where and can get lost very easy.
there is also a nice look out, out near coramba, and a nice little stream on the top of the range.
i might be able to do a bit of a tour on the weekend?
