One day
Start in the medina at the Ribat, climbing the tower for the view, then see the Great Mosque and wander the covered souks. Climb to the Kasbah for the Roman mosaics in the Archaeological Museum, have a Tunisian lunch of couscous or brik, and spend the afternoon on Boujaffar beach and the corniche. End with a seafood dinner on the seafront or up at Port El Kantaoui's marina.
