Barcelona is a city where you could spend weeks and still not see everything. The Gaudi buildings alone demand several days: the Sagrada Familia, Park Guell, Casa Batllo, La Pedrera and the lesser-known Casa Vincens each deserve a proper visit rather than a rushed photo stop.
Beyond the architecture, the city rewards wandering. Lose yourself in the labyrinth of the Gothic Quarter, walk the seafront promenade from Barceloneta to the Port Olimpic, take the cable car up Montjuic for views across the harbour, or climb Tibidabo for a panorama of the entire city. For football fans, a match at Camp Nou is unforgettable even if you do not follow the sport.
