Uluru is not the world's biggest rock, and that's not the point. It stands 348 meters out of a flat red desert, sandstone about half a billion years old, and for the Anangu, the Traditional Owners, it's part of a living law. The park was handed back to them in 1985, and since 26 October 2019 the climb is closed for good. You walk around the rock now, which is the better way to meet it.
The logic is simple: one resort, Yulara, 20 minutes from the rock, and two sites in the park, Uluru and Kata Tjuta, 50 km apart. Add the Cultural Centre, the walks, a sunrise, a sunset and the Field of Light, and you have three days, which is also exactly what the park pass covers. More days only make sense for Kings Canyon, a long drive away.
Day one is the Cultural Centre and your first sunset, day two Kata Tjuta at dawn and the Field of Light, day three sunrise and the walks around the base of Uluru. It's all planned around the heat: from October to March daytime temperatures regularly exceed 35 degrees and the park closes tracks by the thermometer. Uluru is the one place in Australia where you should read the rules before you go. Start on any weekday: the park, the Cultural Centre and the resort are open every day of the year.
