Smack in the middle of the Australian Outback is a truly massive hunk of rock—and one of the country’s most iconic landmarks: Uluru. Also known by its Western name (Ayers Rock), the sandstone monolith is the top draw in the vast, desert expanse of the Red Centre. The sacred sight magnetizes travelers eager to see a truly ancient edifice (it’s thought to have started forming 550 million years ago) and its daily light shows: The rock appears to change color—from charcoal to purple to crimson to ochre—with every sunrise and sunset. Some of the best things to do in the area include helicopter rides, camping, and walking the base of Uluru with an Indigenous guide.
