Nice flattish grassy areas with lots of potential camping spots all the way along the Jounama Creek.
Access for the first part is along a very short dirt track directly opposite the entry road to Talbingo, and could be managed by almost any vehicle.
Further access up the track may require 4WD.
Non-Drinking water could be available from the creek most of the time.
I vaguely recall there were toilets there, but am not certain as the last time I camped there was a while back.
But it was a really tranquil and pretty spot, and made a great overnight stop for a round trip from Canberra to Yarrangobilly and home via Tumut and the Brindabellas.
