Devils Marbles (also known by the Aboriginal name Karlu Karlu) is an Outback reserve protecting a natural landmark in the Barkly Tableland region of the Northern Territory, located just off the Stuart Highway.
Devils Marbles are large granitic boulders precariously balanced on top of one another, which glow fiery red as sunset hits. They make for a nice stopover on the long Stuart Highway, and are culturally significant to the traditional Aboriginal owners, the Warumungu, who believe that these are the eggs of the Rainbow Serpent – a creature of a Dreamtime story.
The 'marbles' themselves are the main landscape feature. The surrounding is mostly flat desert.
The area is a desert. In the summer, temperatures get very high, while nights can get very cold.
This area is hot and dry - drink a lot of water.
