Wadi Rum, South Jordan
This desert covers 277 square miles, or 717 square kilometers, and looks like the surface of Saturn. This dramatic wilderness encompasses much of South Jordan, and its wide sandy valleys scratch over a mile, or 1600 meters, high. This is a UNESCO World Heritage Site with natural arches, narrow gorges, landslides, and caverns. It’s here you’ll find 25,000 rock carvings and 20,000 inscriptions that trace human evolution back millions of years (WHC).
