Many of Moroccan’s rich crafts are made by Fez artisans. For hundreds of years such work has been regulated by traditional guilds, ensuring the highest quality. Each district has its own specialty: It's hard to get your grip on Fez. This may be partly because there are three towns in Fez: the two ancient walled areas Fes-l-Bali (the old town) and Fes-l-Jdid (the new town) and the more modern French-built Ville Nouvelle. But let this not scare you! Fez is one of the best sights in the world. The walled cities are the main attraction of Fez. The whole old city of Fez has been declared a UNESCO World Heritage site. The immense Medina of Fes-l-Bali is a huge labyrinth. In order not to get lost it is best to keep in mind that when you walk down you go towards the center, when you walk up, you leave the center. The gates that are part of the walls are part of some amazing architecture. Within the walls you should at least try to find the Medersa Attarine, the Medersa Cherratine and Medersa Seffarine, three stunning old buildings near the center of the maze. The other thing you shouldn't miss is the people at work in the median: coppersmith, tanners, dyers. Spectacular colours and lousy working conditions make for great pictures. Just outside the walls are two good museums Borj Nord (exhibiting weapons) and Dar Batha (Moroccan arts) and the Royal Palace

It is a must for people who care about culture and living crafts, the city at night looks awesome from the high terraces and roofs of the traditional houses, just outside the Medina you can eat at Palais de Fes, an amazing place with amazing Moroccan food.
The tanneries is one of the most famous scenes in Fes, people are competing to take tourists to the highest terrace to have the best view for the tanneries and to take better photos of it.
Simply it is a city full of colors, details, and crafts

The Medina of Fez is a spectacular place to experience the traditional culture...but this does include fighting through the crowds and dodging the numerous sellers who are determined to make you buy their products you can do without. Being a single woman, walking alone through this medina was not the best choice. I would recommend going with someone or better yet join a group that way you will just get to enjoy the atmosphere without the stress of being lost or harassed.

Getting there is really exciting. You will walk along narrow, crowded, dirty streets. It is one of the oldest Souks that I have ever been.

Straight out of a scene from Raiders of the Lost Ark. You don't get any more authentic than this.
