The Al-Khubta Mountain. This mountain range is a natural barrier on the eastern ridge of the Petra Basin. The newly restored stairway provides easy access to the top. A niche on the way is dedicated by Wahballah to the goddess al-‘Uzza and to the Lord of the Temple. At least three High Places are carved or built at the top. Several idol niches, cisterns and a large water reservoir are spread out on the flat top of the plateau. Text from notice on site.
On the top one can continue to a point where you can look down on The Treasury, great spot.
