One of the few towns along the Desert Highway is Qatrana, a couple of kilometres north of the turn-off to Karak, and a former stop on the pilgrim road between Damascus and Mecca. The only reason to stop here (if you have your own transport) is to have a quick look at Qatrana Castle, built in 1531 by the Ottomans. It has been nicely restored, but there are no explanation boards.
