Both sides of the Jordan River belong to a unique land-bridge joining Africa with Asia and Europe. Both abound in nature and history. On the east side, the Hashemite Kingdom of Jordan has preserved large stretches in their pristine beauty. We can walk through a forest of pillars in Roman Jerash and spend another half day in the real forests around it. We will want a day at Petra, now counted among our world’s seven wonders, but just 40 miles to the south is Jordan’s most stupendous landscape, Wadi Rum: wide valleys flanked by silent twisted giants—mountains rising from an ocean of sand, inviting the hiker.
