At 3.6km long and rising 348m from the earth to top, Uluru is a hugely impressive sight. But remember, two-thirds of the rock lies beneath the earth. The colours of Uluru changes dramatically as the day passes. In the afternoon, you may see an ochre-brown colour with lots of dark shadows. As the sun sets, it bursts into bright orange, then a series of deeper and darker reds before it fades into black. Dawn is the reverse scenario.
Neighbouring Kata Tjuta is explored on foot. Kata Tjuta, once known as The Olgas, are a striking group of domed rocks huddled together 35km west of Uluru. There are 36 boulders standing shoulder to shoulder, forming deep valleys and steep gorges. The tallest rock, at 546m is 200m higher than Uluru.
The 7.4km Valley of the Winds loop (2-4 hours) is one of the most challenging and rewarding, but the shorter Walpa Gorge (2.6km return, 45 minutes) is especially beautiful in the afternoon, when sunlight floods the gorge. Like Uluru, Kata Tjuta is at its blood-red best at sunset.
