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.
