Barcelona

Barcelona seduces visitors with its unique blend of beach culture, Gothic architecture, and the fantastical creations of Antoni Gaudi. The Sagrada Familia, still under construction after more than a century, remains one of the most awe-inspiring buildings on Earth. Strolling down Las Ramblas, ducking into the Gothic Quarter's medieval lanes, or watching the sun set from Bunkers del Carmel, every corner of the city rewards exploration.

The Catalan capital is equally serious about food and nightlife. Tapas bars overflow with patatas bravas and jamon iberico, La Boqueria market is a feast for the senses, and the city's restaurants regularly appear on world's-best lists. After dinner, the nightlife stretches well past dawn.
