Hundreds of rounded granite boulders, some balanced improbably on others, scattered across a shallow valley in the middle of the Northern Territory.

Karlu Karlu is a field of granite tors formed by spheroidal weathering: a 1.7-billion-year-old granite mass cracked into blocks, and water rounded the corners of each block underground before erosion exposed them. The result is boulders up to 6 m across, split cleanly in half or perched on pedestals. At sunrise and sunset the rock goes deep orange.

The site is sacred to the Warumungu, Kaytetye, Alyawarra and Warlpiri peoples; the name means "round boulders".

Why it stays quiet

It is 400 km from Alice Springs and 1,000 km from Darwin, on a highway most tourists drive straight through. Campers stop for a night; day visitors are rare.
