This mammoth rock is commonly believed to be the biggest monolith in the world, however, that distinction goes to another Australian outcrop - Mount Augustus in Western Australia. To reach the top of Uluru, you would need to climb 1.6 kms and its perimeter is some 10 kms. As this is a sacred site to the local indigenous people, climbing the rock is now regarded by most Australians as a mark of disrespect.
