Barcelona's metro is compact, easy to navigate and covers almost every neighbourhood a visitor is likely to want to reach. Combined with the city's efficient bus network, the FGC suburban railway, and the Aerobús link to the airport, public transport is the obvious way to get around — especially given that parking is expensive and the city centre is best explored on foot or underground. Here is how the system works.
The metro network
The Barcelona Metro is operated by TMB (Transports Metropolitans de Barcelona) and has 12 lines, though visitors tend to use Lines L1 through L5 most frequently. The network covers the city from the seaside at Barceloneta up to Gracia, Sarrià–Sant Gervasi and Horta; laterally from Sants and Hospitalet in the west to Poblenou and beyond in the east.
Key lines for tourists:
- L1 (red): The main east–west spine, running from Fondo in the east through Plaça de Catalunya, Urgell, and out to Hospital de Bellvitge. Most visitors use it for Plaça de Catalunya (the centre of everything) and connections to the seafront.
- L2 (purple): Useful for reaching the Sagrada Família and Passeig de Gràcia from the east side.
- L3 (green): Another crucial north–south line through the city, serving Liceu (Gothic Quarter), Passeig de Gràcia, Diagonal and Nou Barris.
- L4 (yellow): Runs along the coast from La Pau, stopping at Jaume I (Gothic Quarter), Barceloneta, and the Vila Olímpica (Olympic Village).
- L5 (blue): Runs from Cornellà through Sagrada Família to Vall d'Hebron.
Trains run from roughly 05:00 to midnight on weekdays, and through the night on Fridays and Saturdays — an unusual and genuinely useful feature for a city with Barcelona's nightlife reputation.
FGC: the other rail network
The FGC (Ferrocarrils de la Generalitat de Catalunya) is a separate suburban rail network that overlaps with the TMB metro in central Barcelona but extends further out into the suburbs and foothills. Key FGC routes for visitors include lines to Sant Cugat and Sabadell in the north, and — most importantly — the L6/L7 lines to Sarrià, which give easy access to upper Tibidabo and the Collserola hills.
The same TMB/integrated tickets are valid on FGC within the city zones, so you do not need to buy separately unless travelling into the outer zones. FGC stations are marked on the metro map and usually clearly signed.
Tickets and the T-Casual card
Barcelona uses an integrated zone-based fare system covering TMB metro, buses, FGC, TRAM and Rodalies (Renfe suburban rail). Zone 1 covers the city centre and is what most visitors need.
The most useful ticket options for visitors:
- T-Casual (10-journey card): Ten metro/bus/tram trips within one zone at the best per-journey rate available. Can be shared between multiple travellers travelling together. This replaced the old T-10 and is the standard go-to for most visitors.
- T-Dia (daily pass): Unlimited journeys for one calendar day. Good value if you are making many trips.
- Hola Barcelona Travel Card: A tourist card valid for 2, 3, 4 or 5 consecutive days, covering unlimited travel on metro, bus, FGC and Rodalies within Zone 1. Also includes airport transport. Sold at the airport, tourist offices and online. This is the best option if you want to include airport transit without worrying about extra fare zones.
Buy tickets at the orange vending machines inside any metro station. The machines have an English option and accept cards. The T-Casual card requires a separate plastic card (small additional cost for the card itself).
Airport fares: The Barcelona Airport (El Prat) is served by the Aerobús and by Rodalies (RENFE R2 Nord) rather than the TMB metro. The R2 Nord from the airport requires a Zone 4 ticket or the Hola Barcelona card — standard T-Casual and T-Dia tickets are NOT valid for the airport leg. Check carefully before travelling.
Bus, tram and night buses
Barcelona's bus network is comprehensive and shares the same ticketing as the metro. The Bus Turístic is a separate hop-on hop-off tourist bus that is not part of the public transport system and requires its own ticket — useful for orientation on a first day, but not a substitute for the regular network.
The TRAM network covers two separate areas: the Trambaix (west, towards Sant Joan Despí) and the Trambesòs (east, along the coast towards Sant Adrià). It is less central to most visitor itineraries but uses the same tickets.
Late-night buses — the Nitbus network — cover the city through the night on weekdays when the metro is closed. On Friday and Saturday nights the all-night metro makes the Nitbus less critical, but it remains useful on Sunday through Thursday nights.
Practical tips for Barcelona
- Plaça de Catalunya is the main metro interchange and the centre of the surface bus network. If you are disoriented, aim for Plaça de Catalunya and reorient from there.
- The L2 and L5 both stop at Sagrada Família. It is extremely busy; arrive early in the day or book timed-entry tickets far in advance.
- Pickpocketing is a serious problem in Barcelona, particularly on the L1 between Plaça de Catalunya and Barceloneta, and on the Aerobús. Use a zipped bag and keep phones out of back pockets.
- The Barceloneta seafront and the Gothic Quarter are both within comfortable walking distance of the metro — you do not need to take a taxi everywhere once you are in the centre.
For intercity travel from Barcelona, the Barcelona Sants station is the main departure point for AVE high-speed trains to Madrid, Valencia and Seville, as well as the direct train to Paris. See our guide to the Paris–Barcelona train for details, and our Madrid Metro guide for tips on the capital's underground system.
Frequently asked questions
What is the best metro ticket for tourists in Barcelona?
The T-Casual (10-journey card) offers the best per-trip rate and can be shared between travellers. For unlimited travel over several days, the Hola Barcelona Travel Card is convenient and includes airport transit.
Does the Barcelona Metro run 24 hours?
On Friday and Saturday nights (into Saturday and Sunday mornings), the metro runs through the night. On other nights it closes around midnight and Nitbus night buses take over. Weekend all-night service is one of Barcelona's more visitor-friendly features.
Can I get to Barcelona Airport (El Prat) on the metro?
Not directly — the TMB metro does not reach El Prat. The Aerobús coach and the Rodalies R2 Nord train both serve the airport. Standard T-Casual cards are not valid for the airport rail leg; you need a Zone 4 ticket or the Hola Barcelona card.
Which metro line goes to the Sagrada Família?
Both L2 (purple) and L5 (blue) stop at Sagrada Família station. From the city centre, L5 from Diagonal or Verdaguer is often the straightforward option.
