Kata Tjuṯa, or the Olgas, consists of 36 dome-shaped monoliths that are as impressive as Uluṟu (Ayers Rock). Its name means 'many heads', which refers to the monoliths. The region around Kata Tjuṯa is known as the Valley of the Winds and a 6 km (4 mi) long circuit takes you past all the sights.

The highest monolith is 1,066 m (3,497 ft) high Mount Olga, which is actually much higher than Uluṟu, 25 km (16 mi) to the east.

Kata Tjuta is in the center of Australia, in the southern part of the Northern Territory, 1,430 km south of Darwin and 2,100 km northwest of Canberra. Kata Tjuṯa and Uluṟu are both part of the Uluṟu-Kata Tjuṯa National Park.
