The capital of Catalonia, Barcelona, is one of the most beautiful and vibrant places in Spain, perhaps even in Europe. A city of contrasts, it is like no other in Spain; this is more evident in its architecture, a marriage of Gothic tips and modern curves.
Barcelona is also a city of distinct neighborhoods. The old city - Ciutat Vella - is the heart of everything, with museums, shops, and cafes. Then there is the port area, Port Vell, which has bars, restaurants, shops, an IMAX theatre, and the largest aquarium in Europe.  Enchanting and ancient, the Barrio 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 the best qualities of Barcelona is that its neighborhoods are surprisingly easy to explore on foot although a convenient metro and bus network will easily accompany you from one barrio to another. Do not miss a walk along the Ramblas, full of products and flower stands.
