Uluru is one of Australia's most recognisable natural landmarks. The sandstone formation stands 348 m (1,142 ft) high, rising 863 m (2,831 ft) above sea level, with most of its bulk lying underground, and has a total circumference of 9.4 km (5.8 mi).Both Uluru and the nearby Kata Tjuta formation have great cultural significance for the Aṉangu people, the traditional inhabitants of the area, who lead walking tours to inform visitors about the local flora and fauna, bush foods and the Aboriginal dreamtime stories of the area.
