Once leaving Holloway's track the Razor back Spur track narrows a bit but is easy going. The Wombat track descends into the valley along a ridge for a km or two then drops into the valley from 1360m altitude down to about 500m very rapidly. Good rocky grip on the first decent but down lower becomes very muddy. Crossing the creek at the bottom of the spur is usually pretty easy. Great camping spot at the Post Office cabin in the valley.
