Rising out of nowhere, the massive monolith dominates the outback and the eye. Visitors can watch spellbound as the rock’s light show cascades through otherworldly reds, oranges, yellows and pinks, reflecting the clouds and sky above. It’s also possible to walk around or climb the sandstone giant. Sunset is when the rock literally glows, though, and practically pulses through the light changes, cementing its status as the heart of Australia.
