Approximately a 10-minute drive northeast of the town of Judah – or around two and half hours’ drive from Jubail – you’ll find the Devil’s Thumb, a towering rock formation that rears out of the desert, like, as its name suggests, a looming thumb. Head out in convoy for an off-road day trip and explore the nearby escarpments, which are full of surprises in the form of hidden caves and rugged rock formations and watch for camels winding their way across the sands. You can even camp for the night. Just don’t expect to get much sleep: the star-lidded skies here are out of this world.
