Connecting the two legendary sites of Wadi Rum and Petra is a week-long trek across one of the  longest stretches of wilderness on the Jordan Trail. Here in the empty but striking desert, with its  dramatic rock formations, stargazing and peace are found at their best. Starting with open, sandy  plains and moving into deep, rugged wadis, this section of the trail takes you deep into the places  where humans seldom go. This section’s most dramatic and memorable aspect is the arrival at  the Nabatean masterpiece, Petra.
