With broad boulevards, big skies and intriguing architecture competing for your eye, Barcelona is a city unlike any other. The streets beg to be walked, as you can amble through the centuries with a stroll from the narrow medieval alleyways of the Gothic Quarter to the modern heart of La Rambla. Along this wide, tree-lined promenade, experience the full gamut of Catalonian culture, from whimsical Gaudí homes to tapas bars to bustling La Boqueria market. Climb the hill to Park Güell to see more of Gaudí’s unmistakable imprint. Or stay closer to the port and walk amidst the extensive Roman ruins of Tarragona, a UNESCO World Heritage site.
