Bundalong, there is a camping area in the Lower Ovens state park and there are all the backwaters of the lake as well as the Ovens and Murray rivers, just have to watch out for us water skiers in the Murray, they have stopped skiing in most of the ovens now. Gets a bit crowded in peak times nowdays but still a good spot as there are miles of backwaters to explore in a boat / canoe.
Whack this into google maps -36.0557,146.20746 this is the main camping area
