Ad-Dahnā'

Ad-Dahna is an arc of reddish sand linking the Nafud with the Rub' al-Khali across the Arabian interior. To its north, the settlement of Linah is known for hundreds of wells cut into rock. Linah was a stopping place for caravans on the Darb Zubaydah, the pilgrimage route across northern Arabia, where travellers could replenish their water before continuing their journey.
