Gibraltar Ranges National Park, NSW

There is a longer walk through Washpool which is 8.5 kilometres in length. Initially, it twists and turns along the Coombadjha Creek. It then climbs through hardwood forest - bluegum, brushbox and tallowwood to the top of a ridge, before descending again, past Bill Haydon's trees, into deep green subtropical rainforest. It will take 3-5 hours, depending upon your speed.
