One of the important and must visit places in Jordan is Wadi rum. Wadi Rum also known as The Valley of the Moon (Arabic: وادي القمر) is a valley cut into the sandstone and granite rock in south Jordan at 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 highest elevation in Wadi Rum is Mount Um Dami at more than 1,800 m (5,900 ft) above sea level.
The visit can be done in a day together with Petra. But if you are an outdoor freak, you easily spend a week at the wadi, do all sort of things, from camping, mountain climbing, photographing sunset and sunrise or just exploring. Of course, dont miss the famous Seven pillars of wisdom ( Seven Pillars of Wisdom: A Triumph is the autobiographical account of the experiences of British soldier T. E. Lawrence (“Lawrence of Arabia”), while serving as a liaison officer with rebel forces during the Arab Revolt against the Ottoman Turks of 1916 to 1918. Charles Hill has called the Seven Pillars “a novel traveling under the cover of autobiography,” capturing Lawrence’s highly personal version of the historical events described in the book.)
