The city curves around a bay with looming mountains hard behind. Travel up steep-walled canyons into the dramatic valleys where Lawrence of Arabia's armies harassed the occupying Turks. Continue past Wadi Rhum, still home to nomad Bedouin, until you reach the awe-inspiring, rock-cut city of Petra, one of the "lost" cities rediscovered in the 19th century. None is more dramatic nor more mysterious than Petra, the "rose-red city half as old as time." The only entrance to Petra, the Siq, is a twisting mile of narrow passage between soaring walls of sandstone, which made the entrance to Petra both difficult to find and easy to defend. Travel along a marble-paved Roman road, surrounded by huge and elaborate structures carved into the brilliantly-colored rocks of the cliffs. Visit the so-called Royal Tombs, and the Roman Thearer. Then, stunned to silence by the majesty of Petra, return up the Siq and to Aqaba.
