Uluru, also known as Ayers Rock, is a large sandstone formation in central Australia that is sacred to Aboriginal Australians. It was formed over 600 million years ago and Aboriginal people have lived in the area for 10,000 years. The Indigenous people own the land, while the Australian government holds a 99-year lease to operate it as a national park. Uluru is 3.6 km long, 1.9 km wide, and its circumference is 9.4 km, with a 1.6 km climb to the summit. Visitors can see colorful sunrises and sunsets on the rock, Aboriginal rock art, and walk or climb Uluru.
