Things to do
Barcelona joins a medieval Gothic Quarter, the Eixample grid with Gaudí's houses and a seafront that ends at Barceloneta beach. The city is compact, but Montjuïc and Park Güell sit on hills, so alternate walking routes with metro rides across town.
Sagrada Família and the Eixample
Gaudí's basilica rises in the upper Eixample, close to Casa Batlló and La Pedrera on the Passeig de Gràcia. Allow time for the towers, then give the afternoon to the avenue and its shopfronts.
Gothic Quarter and El Born
Walk from the cathedral through narrow lanes to Plaça Sant Jaume and on into El Born. The Picasso Museum holds his early work, and the route ends at the waterfront.
Park Güell and Gràcia
Park Güell climbs above the city and reads as a mosaic on the hillside. Come at opening, walk the terraces, then drop into Gràcia and eat lunch on one of its squares.
Where to stay
Gothic Quarter
The Gothic Quarter rewards long walks, but nights are noisy and there is almost no green space. Rooms cost more, though the beach and the station are within reach on foot.
Eixample
The Eixample works because of its grid: metro, shops and Gaudí's buildings are close. Flats face quiet inner courtyards, while the wide avenues carry traffic and noise by day.
Gràcia
Gràcia keeps a village character: squares where people sit with a glass, small bars and few cars. The centre is twenty minutes by metro, and the evening here runs long.
Getting to and around Barcelona
El Prat airport connects to Plaça Catalunya by the Aerobús and to the university area by metro L9 Sud with a change. The metro and trams cover the city, while the old centre and El Born are best on foot. Bicing bikes suit the seafront, and a cable car climbs Montjuïc.
Three days in Barcelona
Gothic Quarter and El Born
Start at the cathedral, walk to Plaça Sant Jaume and into El Born. After lunch take the Picasso Museum and Santa Maria del Mar, then finish at the waterfront and Barceloneta.
Gaudí in the Eixample
Morning at the Sagrada Família with a lift up one tower, then the Passeig de Gràcia to Casa Batlló and La Pedrera. Dinner waits at a restaurant in the Eixample.
Park Güell and Gràcia
Climb to Park Güell at opening, walk the terraces and come down into Gràcia. Lunch on a square, then a walk to Casa Vicens and tapas in the evening.
