The morning air in Aqaba tastes faintly of the Red Sea—salt and diesel—and the driver’s van hums awake as street vendors fold awnings. Within two hours the coastal town falls away and the road climbs into the ochre hills that give way to Petra’s rose-red cliffs. You enter Petra the way caravans did centuries ago: through the Siq, a 1.2-kilometer cleft that funnels light and sound toward Al-Khazneh, the Treasury, which appears like a carved mirage. The site pushes you to walk: flat colonnaded avenues, packed-pebble courtyards, and staircases carved into sandstone that lead to hilltop tombs and the Monastery—Ad Deir—reached after roughly 800 steps and a steady 2–2.5 km climb from the valley floor.
