The Great South West Walk is a 250-kilometre (155 mi) walking track, established in 1981, and located predominately in the Barwon South West region of Victoria, Australia. Much of the course of the track passes through the Lower Glenelg National Park, the Cobboboonee National Park, the Discovery Bay Coastal Park, the Mount Richmond National Park and the Cape Nelson State Park, and may be explored through shorter or overnight hikes, or the entire 12- to 14-day circular hike, starting and finishing in either Portland or Nelson. A short portion of the track is located in South Australia, near Donovans.[2]
