Come to Taouz to spot mineral formations and possibly dinosaur bones where the desert swallows the road. Between Merzouga and Taouz is the village of Khamlia, whose inhabitants are believed to be descended from escaped slaves. This frontier town is home to notable Gnawa musicians, including Les Pigeons du Sable (Sand Pigeons). Their music is available online, and they occasionally perform locally and at Er-Rachidia’s Festival du Desert. Ask at their house (marked by a banner) for details.
