One itinerary could be the tour in the center of Naples.
Starting from the port you can reach Plebiscito square in few minutes where there is the XVII century Royal Palace, the San Carlo theatre, the most ancient opera theatre in Europe, and San Francesco di Paola church, all of them to be visited.
After a coffe break at one of the most important Litery Cafè of Italy, Gambrinus, you may go straight ahead along Chiaia street until Piazza Dei Martiri, one of the most elegant and symbolic place of the city and then go down Calabritto street, where you might get yourself a gift in one of the fashionable boutiques of this street. If you are a stylish man you might have a look at the wonderful ties in Marinella atelier in Vittoria square, in front of which is the seafront. This is via Caracciolo, immortalized in thousands of cards showing Naples bay with its Castel dell’Ovo that is worth a visit to enjoy the stunning view from the terraces and take some photos.
Of course during this walk you will meet many restaurants and pizzerias where to have a rest and eat a good pizza or some seafood looking at the sea…
But if you want to celebrate a special anniversary you can cross the street and go to the terrace of a five star Deluxe hotel the “Vesuvio” and have dinner at its restaurant, the “Caruso”.
At this point you may easily reach the port and your ship.
