How do I get around Barcelona?

The metro does most of the work. TMB runs eight lines that cover every neighbourhood a first-time visitor cares about, and the T-Casual card: 11.35€ for ten trips, about $13.30: is the only ticket worth buying. Load it at any station's touchscreen machine (they do English fine) and it scans on metro, bus, tram, and commuter rail within Zone 1. The lines that matter: L3 green connects Plaça Catalunya, Passeig de Gràcia, and Diagonal; three stations you'll hit constantly. L4 yellow runs to Barceloneta beach and the Born. L1 red gets you to Arc de Triomf and Hospital de Sant Pau near Sagrada Família. One transfer covers almost anywhere. Trains come every three to five minutes, so you never check a schedule. The catch is closing time: midnight Sunday through Thursday, 2 a.m. Fridays, all night Saturdays. That weeknight midnight cutoff bites harder than you'd think: dinner here rarely starts before 9 p.m., and one post-dinner drink puts you past the last train.

Barcelona rewards walking more than most European cities because Ildefons Cerdà's 1859 grid gave the Eixample wide pavements, chamfered corners that open into small plazas at every intersection, and a built-in compass: mountains uphill, sea downhill. Plaça Catalunya to Sagrada Família is about 35 minutes on foot. Gothic Quarter to Barceloneta, maybe 15. You'll feel the shift underfoot when you cross into the Barri Gòtic: smooth granite slabs give way to uneven medieval stone, and the alleys tighten until you could stretch your arms and brush both walls. Bring shoes with grip for those passages. Summer changes everything. From late June through September the pavement throws heat back at you by early afternoon (35°C in the shade, worse at ankle level) and the shaded side of any Eixample boulevard becomes the only tolerable route between noon and five. The plane trees along Rambla de Catalunya and Passeig de Sant Joan throw decent cover. La Rambla is fine for one walk to see it. After that, use the parallel streets: less crowded, fewer pickpockets, better shops.

Taxis are black and yellow, metered, and straight: Barcelona is not a city where you fight for the fare. Flagfall sits around 2.30€ with roughly 1.21€ per kilometre after; a ride from Barceloneta to Gràcia runs 8–12€ depending on traffic. Uber technically operates but dispatches the same licensed taxi fleet, so there is no price edge over flagging one down. The apps worth downloading are Free Now and Cabify. Cabify tends to price a little lower on weekend nights when demand spikes around 2 a.m. near Poble Sec and the Raval. One thing that might surprise you: taxi meters here are honest enough that the app is a convenience, not a survival tool. After midnight Sunday through Thursday, when the metro shuts, a taxi is how you get home. A 3 a.m. ride from the Raval to Gràcia costs about 10€: cheaper than a second round of drinks at most cocktail bars in Sant Antoni.

Skip the hop-on-hop-off bus. The route covers ground you can walk or metro for a tenth of the 30€+ fare, and you'll spend half your time crawling through Eixample traffic watching the same beige apartment blocks slide past at 8 km/h. The exception is Montjuïc: the hill is steep, and while the funicular from Paral·lel metro handles the first pitch, the bus or Telefèric cable car saves a hot uphill slog to the castle and the Miró foundation. Bikes work along the seafront promenade from Barceloneta to the Fòrum, where the path is flat and separated from traffic. Inland, the Eixample bike lanes mix you with delivery scooters doing 40 km/h. It feels less safe than the painted lane suggests. Rent from a shop in Barceloneta for the coast; skip Bicing, which requires an annual resident subscription. One last note: the T-Casual does not work on the Aerobus from the airport. That is a separate 7.75€ ticket: see the airport-to-city guide for the full breakdown.
