The Port Davey Track, officially the Old Port Davey Track, is a bushwalking track located in the south western region of Tasmania, Australia. The 70-kilometre (43 mi) track traverses remote wilderness within the Southwest National Park, part of the Tasmanian Wilderness World Heritage Site, and is managed as a wilderness walk. The Tasmanian Parks & Wildlife Service recommend that experienced bushwalkers can take four-to-five days to cover the track in one direction.
