The challenging six- to eight-day South Coast Track starts (or ends) at Cockle Creek, tracking between here and remote Melaleuca in the Southwest National Park. Combined with the Port Davey Track you can walk all the way to Lake Pedder, though it'd take about two weeks. Shorter walks from Cockle Creek include ambles along the shoreline to the lighthouse at Fishers Point (4km, two hours return; best done at low tide), and a section of the South Coast Track to South Cape Bay (15.4km, four to five hours return). National-park entry fees apply; self-register at Cockle Creek.
