The Mountain of Smoke (Arabic: جبل الدخان‎, Jabal ad Dukhan) is a hill in the Southern Governorate of Bahrain. At 134 m (440 ft) above mean sea level, it is the country's highest point. The Mountain of Smoke is named as such because of the haze which often surrounds it on humid days. A number of caves of indeterminate type are in the vicinity of the mountain.
