Australia's Uluru at sunset © Tourism NT

The wow factor: Formerly known as Ayers Rock, this UNESCO World Heritage Site is a landmark almost in the geographical centre of Australia and sacred to the local Aboriginal people. It rises 1,260ft (384m) from the flat Outback of Northern Territory and measures 2.2 miles (3.6km) long by 1.2 miles (2km) wide. Throughout the day, and especially at sunset, it changes colour to a multitude of hues.

Did you know? Uluru is like a giant iceberg; most of its bulk is below the surface – around 3.7 miles (6km) deep!

Experience: Travelbag offers a five-day Discover the Red Centre self-drive tour, including Alice Springs and Kings Canyon as well as Uluru, from £2,199 per person including return international flights into Darwin, car hire and accommodation. Intrepid Travel’s three-day Central Rock & Canyon tour also visits Kata Tjuta (The Olgas) and Kings Canyon and costs from £370pp including two nights’ camping.,
