OK, I'll put up some things that might be of interest for those down here for the GTG.
Obviously, I like Sandy Cape - if accessable.
There is the township of Balfour (can be accessed without doing the Balfour track) in the same area.
I also like Montezuma Falls on the West Coast.
Of course there is the Balfour track for those that want to do it.
I'm sure others will chime in with other ideas.
