Tetouan's medina is UNESCO-listed and, unlike the larger medinas of Fes or Marrakech, has barely been touched by mass tourism. Narrow whitewashed lanes climb gently from Place Hassan II toward Bab el-Okla, branching into specialist souks for leather, jewellery, fabric, and silver. The trades are still organised by guild; you will walk through a street of tinsmiths, turn a corner, and find yourself among carpenters.
An official guide from the tourist office on Rue Mohammed V costs little and is genuinely useful — both for navigating and for keeping the more persistent touts at bay. Allow at least half a day. The medina is most atmospheric in the late afternoon, when the sun reaches the white walls at an angle and the call to prayer ricochets around the stone.
