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 . This series of valleys covered in softly colored sand, punctuated by huge, imposing, fantastically shaped jebels, is one of the most memorable destinations in Jordan, and has been so since the dawn of time. Deep in the valleys, far from any visible human habitation, it is possible to believe the view has not changed much since the beginnings of human habitation in the Valley of the Moon, approximately 800 Be. T.E. Lawrence, the legendary Lawrence of Arabia, came here many times, both in his pursuit of success during the Great Arab Revolt of 1917-1918, but also because he found solace in the isolation of Wadi Rum. Rum still rewards visitors today with peace and unceasing beauty.
The trail starts at the Visitor Center near the Mujib Bridge, where you will take the cantilevered walkway over the dam and follow the course of the river between towering sandstone cliffs to the base of a large waterfall. Depending on seasonal rainfall levels, the gorge may contain pools deep enough for swimming. This is an ideal walk to take slowly and enjoy the cool water and shade, especially in the heat of the summer.
