Circumnavigating Sugarloaf Reservoir, guided by Top Walks in Victoria by Melanie Ball.
Most of it was marked by orange markers, but in a few places the only way was to follow the shoreline until another marker was sighted.
At 18km (16km according to the book) it was our longest walk to date. The scenery and terrain varied from rural, industrial, to bush. Well worth doing despite the aching legs and feet at the end. Kyle and Connor led most of the way and coped very well.
