The Peak River rises below Bogong Peaks, on the northeastern slopes of Mount Bogong within the Bongong Range, part of the Snowy Mountains, contained within the Kosciuszko National Park. The river flows generally north before reaching its confluence with the Goobarragandra River near Macks Crossing.[1] The river descends 720 metres (2,360 ft) over its 21-kilometre (13 mi) course.[2]
