Wadi Rum, Nature reserve is by far one of the greatest desert experiences I have ever had (Baring Jaisalmer, because Rajasthani for life *wink wink*). Described by Lawrence of Arabia as "Vast and echoing" Wadi Rum is an outstanding desert landscape. This remarkable landscape is a protected area, it covers over 700 sq. km. One can spend days and weeks exploring it.
Wadi Rum is home to the Bedouins, a tribe known for their hospitality, craftsmanship and sweet tea. A lot of them earn their living via tourism in this area. My experience with them has been exquisite. A Large part of the desert is covered by red sand dunes, canyons, mountains and white sand. The fauna includes Syrian Wolf, Nubian Ibex and striped Hyena.
