We have a run through
Yengo National Park tomorrow but that's a bit north of you. Haven't planned too many down in your direction because I don't know the area.
If you put a run together, we'd be happy to get ourselves organised to come along. Some of the country around Tumut is very nice.
I know of one challenging track that I used to go to on my motorcycle when I went to the Alpine Rally out of Brindebella. There's a large area where we used to camp that would be good for the lunch stage. There's a rock climb and a river crossing in that, or there used to be back in the early 80's.
