From Jordan's port on the Red Sea, you can travel, first by
motorcoach and then for a short distance by horseback, to the
hidden city of Petra. At first it looks like a mirage; rugged
sandstone hills seem to melt into windows and doorways, columns
and gargoyles. But this is not a figment of the desert heat: all
the buildings of Petra, except one, were elaborately carved into
the rock hills by a nomadic Arabian tribe in the 6th century B.C.
It is a remarkable sight. You can also visit Wadi Rum, where
Bedouin families set black goat-hair tents at the base of massive,
striated "jebels," the sheer-faced hills of the region.
