Uluru appears solid and curvaceous from a distance. Up close the curves remain but solidity is tempered with a ‘peeling’, crusty surface that delivers a hollow sound when tapped. The latter fascinated me on my last visit. The third photo is one of the many rock art images – layers and layers over thousands of years – that adorn the overhangs and shallow caves. I love the subtle colours of this waterhole symbol, which is part of an ancient educational blackboard for passing on knowledge to countless younger generations. The base walk is a truly special Uluru highlight that allows you to get up close and personal with the surface, nooks and crannies of this spiritually important place.
