Barcelona

Barcelona is a true global city of breathtaking architecture, countless world-class museums, bustling markets, colorful parks and high-end fashion. This town is big but perfectly discoverable on foot. Imposing Montjuïc Castle is a good starting point for a stunning panorama of the city, and the renowned Joan Miró museum and Catalonian national art museum are also in the area. One might fill an entire day strolling amidst the 12th- and 13th-century architecture of the Gothic Quarter and then checking out the extensive collection of the Museu Picasso.
