Barcelona’s metro system is a crucial part of the city’s public transportation network, providing efficient and extensive coverage across the metropolitan area. Operated by Transports Metropolitans de Barcelona (TMB) and Ferrocarrils de la Generalitat de Catalunya (FGC), the network comprises 12 lines, each identified by a specific color and number.
The most prominent lines include L1 (red line), which connects the eastern and western parts of the city, passing through key areas like Plaça de Catalunya and Plaça d’Espanya. L3 (green line) is another vital route, serving famous spots like Passeig de Gràcia and Les Corts. The L5 (blue line) connects the northeast to the southwest, including major stops like Sagrada Família and Hospital Clínic.
Additionally, newer lines like L9 and L10 offer extended service to more remote areas, including Barcelona-El Prat Airport.
The metro operates from 5:00 AM to midnight on weekdays, with extended hours on weekends and holidays.
