Check if you can join a group tour at Water Clock. If not, this grand structure is still worth a photo from the outside.
This historic landmark is on the to-do lists of many travelers to Fes El Bali. But Water Clock isn't the only drawcard in the area. University of Al Quaraouiyine, Medersa Bou-Inania, and Marinid Tombs are some other recommended attractions nearby.
