The Turton River rises below Trapyard Hill, drawing its source from the southeastern slopes of Mount Wellington and the southwestern slopes of the Moroka Range, both part of the Great Dividing Range. The river flows in a highly meandering course generally south, then west, before reaching its confluence with the Avon River northwest of Briagolong. The entire course of the river is contained within the Avon Wilderness Park. The river descends 1,120 metres (3,670 ft) over its 31-kilometre (19 mi) course.[2]
