this follows part of the Australian Alps Walking track (AAWT) where there are no trail markers or signs and you need to have remote navigation capability
trail passes along and over places called, The Cross Cut Saw, Mt Buggery, Horrible Gap, Mt Speculation (camp), Mt Despair, The Viking (camp at Viking Saddle), Wonnangatta River and the Zeka Spur Track and Wonnangatta Spur and looks down over the Terrible Hollow
requires bush bashing down the Wonnangatta Spur for hours then the awful steep slippery gravel Zeka Spur 4wd track for 5km
likey to have lots of trees fallen on the tack especially on the way to Catherine Saddle
you will need some preparation for this trip and good weather - alpine copperhead snakes are common, as is narrow trails with close scrub, so boots and long gaiters are advisable
two groups can complete this circuit in opposite directions from Mt Howitt Car park and meet at Viking saddle to camp together for the night.
