The term 'Grand Canyon of Arabia' is wholly deserved for this quintessential feature of Oman's spectacular mountain scenery. A short path leads to the edge of the limestone cliffs with a vertiginous 1000m drop into Wadi Ghul below. There are no safety barriers, but the cliff edge is stepped at the top allowing visitors to sit in safety while contemplating the view. There are other viewpoints along the Jebel Shams road, but this is the most expansive.
There's a colourful carpet stall opposite selling key fobs and small rugs.
