Uluru, also known as Ayers Rock and officially gazetted as Uluru / Ayers Rock is a large sandstone rock formation in the southern part of the Northern Territory in central Australia. It lies 335 km (208 mi) south-west of the nearest large town, Alice Springs.

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 food and the Aboriginal dreamtime stories of the area.
