Wadi Rum, often referred to as the Valley of the Moon, is a valley carved out of granite and sandstone in southern Jordan, close to the Saudi Arabian border and roughly 60 kilometers (37 miles) east of the city of Aqaba. It is the biggest wadi (river valley) in Jordan, covering 720 km2 (280 sq mi).
Wadi Rum is home to ruins, rock inscriptions, and petroglyphs from several prehistoric civilizations. It is now a tourist destination with hiking, rock climbing, and guided excursions available. Since 2011, the Wadi Rum Protected Area has been included as a UNESCO World Heritage site.
