Barcelona,

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.
