Ma'an Governorate, in southern Jordan, is the kingdom's largest by area, covering approximately 32,800 km², or 37% of the national territory, with a population approaching 195,000 — the country's lowest density, owing to its vast desert landscapes. It encompasses some of Jordan's most iconic sites, including Petra and the Wadi Rum desert, both inscribed on the UNESCO World Heritage List. The town of Ma'an, the governorate's capital, lies on the ancient King's Highway and was once a stop on the Hejaz railway linking Amman to Medina. A land of Bedouin tribes and Nabataean remains, this mountainous, desert territory rises to 1,854 meters at Jabal Umm ad-Dami, the country's highest point.
