Landscape photographs of New South Wales mountains, rivers and lakes. West of Sydney lie the Blue Mountains, an area of dramatic steep-sided valleys, delicate waterfalls and spectacular scenery. It is one of the most visited regions in New South Wales. In the Barrington Tops National Park near Gloucester are beautiful rivers and forests. Further west, in the outback, is the Darling River, the longest river in the country which with the mighty Murray River forms the biggest river catchment in Australia.
