These are the less-known sisters to Uluru (Ayers Rock), 25km further west. A collection of monoliths, like Uluru, shaped by the wind and water into smooth domes. The tallest is Mt. Olga that stands 546m above the plain, more than 200m higher than Uluru. Tracks wind through the ravines and gorges and make a fantastic hike into the maze of red cliffs. You might even think they are more impressive than Uluru, due to the serenity of place and lack of everything except natural beauty.
