You could get lost for days in the markets and hidden passageways of the old walled city in Fez. If you look like a tourist, you'll have touts following your for most of the way, but you never know -- you might need their help just to find your way back out again! We hired a guide, but in the end don't think we really needed one. If you have a good sense of direction and an adventurous spirit, you can explore on your own. Don't miss seeing the patios choc-a-block with colorful pots of dye where leather is colored.
