The capital of Spain's Catalonia region is one of the country's -- maybe even Europe's -- most beautiful and vibrant places. A city of contrasts, it is like no other in Spain; this is most evident in its architecture, a marriage of Gothic spikes and modern curves. (One name to keep an eye out for is Antoni Gaudi, Barcelona's most famous architect.)
Barcelona is also a city of distinct neighborhoods. The old city -- Ciutat Vella -- is the heart of everything, with museums, shopping and cafes. Then there's the port area, Port Vell, which features bars, restaurants, shops, an IMAX theater and the largest aquarium in Europe. (Port Vell is different to the working port area where cruise ships dock, but it's not too far away.) Enchanting and ancient, the Barri Gotic (Gothic Quarter) is the center of the old city and brings together the best of Barcelona in a series of narrow streets, shops, cafes and magical corridors.
One of Barcelona's best attributes is that while it seems large and spread out, its neighborhoods are surprisingly walkable and easily accessible by bus, metro or even on foot (in comfortable shoes). Don't miss a stroll along Las Ramblas, replete with produce and flower stands, a historic opera house and maybe even a glimpse of Marilyn Monroe calling to you from the balcony of the Erotica Museum.
Just be sure to rest your feet now and then over a few plates of tapas (which are meant to be shared, but we won't tell if you don't) and an ice-cold pitcher of sangria or a bottle of cava, the region's sparkling wine.
