Wadi Rum is the name given to a valley cut into the sandstone and hard rock in southwest Jordan.（46）The name Rum most likely comes from an Aramaic word meaning high or elevated,The area around Wadi Rum is now also one of Jordans most important tourist destinations,and attracts an increasing number of foreign tourists,particularly trekkers（越野者），but also for camel safaris（旅行） or simply day-trippers from Aqaba or Petra.In contrast,there are almost no local or Arab tourists through Popular activities in the desert environment include camping under the stars,riding Arab horses,and rock-climbing amongst the massive rock formations .Jebal Rum（Jebal means mountain ）is 1574 metres above sea level.（47）.
