Carthage is a bit disappointing because not much is left but the trip alone is worth it. Take an electric trolley from Tunis and you can walk to the main part of the site from the Carthage Hannibal trolley stop. The museum is quite good but watch out for "freelancing" guides. The Roman mosaics in the courtyard of the museum are breathtaking and are just casually laying everywhere you look. Also, the view of the sea is fantastic from the hilltop. We tried to find the stadium but never could. Watch your belongings on the trolley!
