Kata Tjuta (literally "Many Heads", formerly known as "Mount Olga" or "The Olgas") is about 50km away from Uluru or Yulara Resort. Strange rounded mountains, like heads of buried giants. There are several walking trails and viewpoints well accessible.
The lush green trees you see in the image are "she-oaks", casuarinas, trees with needle-like leaves well accustomed to the dryness of the area.
