Blue Mountains National Park

The Blue Mountains is a mountainous region in New South Wales, Australia. It borders on Sydney's metropolitan area, its foothills starting approximately 50 kilometres west of the state capital.[1] The area begins on the west side of the Nepean River and extends westward as far as Coxs River[2]. Consisting mainly of a sandstone plateau, the area is dissected by gorges up to 760 metres deep. The highest point of the range is 1,190 metres above sea level. A large part of the Blue Mountains is incorporated into the Greater Blue Mountains Area World Heritage Site, consisting of seven national park areas and a conservation reserve. The Blue Mountains area includes the local government areas of the City of Blue Mountains, the City of Hawkesbury, the City of Lithgow and Oberon.
