Barcelona, Cagliari, Naples

Barcelona is one of the world's greatest treasures, a global capital of commerce, fashion, culture and sunshine. Cruise visitors should start with a walk down Las Ramblas, the glorious tree-shaded thoroughfare at the heart of the city, enjoy a dive in the wonderful beaches nearby, but, most of all, see what visionary architect Antoni Gaudi wrought. Seven of his creations have been honored as UNESCO World Heritage Sites, including La Sagrada Familia, the Park Guell and Casa Mila. Time provided, you can also visit the former Olympic Ring on the hill of Montjuic, home to world-class parks, fountains and museums. Barcelona, which nurtured such artistic giants as Picasso, Dali, Miro and Casals, is definitely a traveler's paradise.

Cagliari, the capital of Sardinia, spreads on a hillside overlooking the aptly named Gulf of Angels. Visit the old Castello Quarter, with the narrow and shaded streets and the old buildings, or enjoy the wide and expansive beaches of Sardinia, basking in the Mediterranean sun. All over the island, there are traces of ancient settlements, such as neolithic ruins at Nora; Phoenician, Cathaginian and Roman relics near Cagliari; and Arab, Genoese and Iberian heritage evident in architecture dating back to the Middle Ages.

Naples is the third-largest municipality in Italy, after Rome and Milan and one of the chief commercial cities of Europe. The city center has been designated a UNESCO World Heritage Site and the surrounding areas are dotted with cultural and historical treasures, with most notable, the restored ruins of Pompeii. Naples itself is mere enduring greatness. Highlights include Castel dell' Ovo, Castelnuovo, Castel Sant'Elmo, a medieval fortress located on a hilltop and national museums dedicated to art and archaeology. There is also a docile bay; the peaceful cypress-tufted islands of Ischia, Procida and Capri and over the city, Mount Vesuvius, volcano and national park. Take the opportunity to see the only active volcano on the European mainland, which blew in A.D. 79 and buried the city of Pompeii, or visit the magnificent Amalfi and Sorrento coasts.
