Wadi Rum also known as The Valley of the Moon is a valley cut into the sandstone and granite rock in southern Jordan 60 km (37 mi) to the east of Aqaba; it is the largest wadi in Jordan. The name Rum most likely comes from an Aramaic root meaning 'high' or 'elevated'. To reflect its proper Arabic pronunciation, archaeologists transcribe it as Wadi Ramm.
The area is centred on the main valley of Wadi Rum. The highest elevation in Wadi Rum is Mount Um Dami at 1,840 m (6,040 ft) high and was first located by Difallah Ateeg, a Zalabia Bedouin from Rum. On a clear day, it is possible to see the Red Sea and the Saudi border from the top.
