The extraordinary Medina of Fez el Bali is an addictive maze of blind alleys and dead-end lanes. You can follow Talâa Kebira, the main thoroughfare, down into its bowels, past goods-laden donkeys and ancient fondouks selling olive oils and a dozen types of honey. Metalworkers hammer away at immense copper cauldrons on Place Seffarine, brightly coloured yarns dry in the heat on Souk Sabbaghine, and workers toil knee-deep in the honeycomb of vats that make up the tanneries Chouwara.
