Take a guided walking tour of the Old City, known locally as Fes el Bali, and step back in time to the labyrinth of the medina. Alive with craftsmen, markets, tanneries and mosques, you’ll pass donkeys piled high with goods (this is one of the largest car-free urban zones in the world) and explore the specialty sections that divide the souks. Medieval Fes was one of the world's great centres of education and culture, both Islamic and Jewish. Its religious institutions and its libraries are legendary. Its mosques are of great renown. Look out for the Medersa Bou Inania, one of the city's most beautiful buildings, which has recently been restored and is now open to tourists. Pass the Belghazi Museum, Medresse el Attarine and the splendid Funduk Nejjarine – a beautifully restored 18th century inn. You'll also see the famous tannery, known for the iconic view overlooking its dye pits, and a ceramics factory where you can see potters working in the traditional way. After the tour, the afternoon is free for you to enjoy as you please. (B)
