Adayra Valley (Arabic: وَادِي ٱلْأَدَيْرَع, romanized: Wādī al-Adayraʿ) runs roughly from north to south, and divides the northern Saudi Arabian city of Ha'il into eastern and western halves.^[1] It starts as a branch of Rimmah Valley in the south, and drains into Qa'a Al-Milh in the town of Baq'a.
