Jordan stages Petra's Treasury carved into rose sandstone, the Wadi Rum desert where Lawrence of Arabia rode, the Dead Sea float at Earth's lowest point, and Jerash's Roman colonnades 50km north of Amman.
Petra walking pleasant before summer heat, wildflowers across Wadi Rum, and Easter pilgrimages to Madaba's mosaic map of the Holy Land.
Petra hits 38°C and the Treasury approach punishing by 10am, but Wadi Rum nights cool to 18°C and the Bedouin camps run star-watching.
Wadi Rum at peak photogenic in autumn light, Petra by Night candles three nights weekly, and Amman pleasant for the Citadel and Roman amphitheatre.
Cool Petra walking with snow possible at high elevation, Wadi Rum nights cold under brilliant stars, and the Dead Sea spas at peak with mineral mud.
