What to see in Casablanca and Tangiers
pkodada,
Welcome to the forum.
It is hard to answer such a broad and curt question. You can find lists of sights to see in a good guidebook. Have you done any research ar all, or is this forum your first stop? Please say what type of things you like to do and see. Are you interested in churches/mosques? Arts? Culture? Historical sights? Natural wonders like mountains or deserts?
The forum is made up of real people who have traveled to the various locations and they provide thoughtful, often detailed answers, but it is helpful to give some parameters. If you just want a list of things to see, you will find that in a guidebook or on the tourist website for those cities.
pkodda,
It would be nice to actually ask a question, instead of entering a subject as if you were "googling" something. As I said before, the forum consists of actual people, not search engines, and more info would also be helpful. Thank you.
