Buses in Barcelona
General introduction
The buses in Barcelona operate on over 100 routes and connect all of the city’s districts and surrounding areas. Buses in Barcelona are highly efficient and easy to use, they are adapted for people with reduced mobility and information regarding the next stops and transfers is provided inside the vehicles. Buses usually run from 5 am – 10 pm and the running times and frequency of service are shared at the bus stops.
- Buses must be entered through the front door and exited using the back doors.
- Wave; you have to make it clear to the driver that you want to get on the bus, otherwise you will have a chance that the bus will not stop.
- Press on the stop button if you want to leave the bus.
- Buses are equipped with ramps and have low floors for easy access.
- Foldable bikes are allowed.
- Electric scooters and wheels are not allowed.
- You can use any ticket purchased from the TMB.
- You can buy and validate the single bus ticket with a bank card on all TMB buses.
- Remember to validate your ticket or you could get a fine.
TMB
Transports Metropolitans de Barcelona (TMB) is the main public transport operator and is the operator for the bus network in Barcelona.
APP
The TMB app gives you quick and easy access to information for your journeys on public transport in Barcelona. Look up the quickest routes, timetables, operating hours, maps, alerts and even purchase transport tickets via the app.
Tickets & bus network in Barcelona
Zones
The network for transport in Barcelona is divided in to zones.
- The entire city of Barcelona and some neighbouring towns are within Zone 1.
- Zones 2 to 6 cover surrounding towns and cities.
The further the distance from Barcelona, the higher the zone number and the higher the cost of the transport ticket.
Tickets
Navigating Barcelona by bus is easy, but understanding the ticket system can be a bit tricky—especially with several transport operators in the city.
While each operator may have its own ticketing system, the ATM integrated fare system is the most convenient option for most travelers. This system allows you to use a single ticket across multiple modes of transport—including TMB buses, metro, tram, and some trains – within a set time frame and zone.
If you’re only planning to take a single bus ride, you can buy a single bus ticket directly on any TMB bus using a bank card. However, this ticket is only valid for that one ride—no transfers allowed. It’s more expensive than using integrated options and is best suited for tourists or occasional riders.
For more flexibility and savings, consider passes like:
- T-casual: 10 rides (1 person only), valid on buses and more.
- T-familiar: 8 rides, can be shared between multiple people.
- T-usual: Unlimited rides for 30 days, great for regular commuters.
- T-jove: Unlimited rides for 90 days, for users under 30.
All these tickets are now available exclusively through the T-mobilitat digital card system, replacing the old magnetic strip cards. Just tap your card when boarding—don’t forget to validate, or you could face a fine!
Prices vary by zone, and special discounted passes exist for students, large families, or people with disabilities.

Bus lines: letters & colours
Diagonally and use numbers 20, 40 and 50. For example, route D20 connects Passeig Marítim with Carrer d’Ernest Lluch.
Llobregat-Besòs direction. The even numbers in the route name indicate whether they run closer to the mountain (lower numbers) or to the sea (higher numbers).
Night bus.
Both ways between the sea and the mountain. The odd numbers in the name indicate whether they run closer to the Llobregat (V3) or the Besòs (V27) rivers.

Night-bus service
Barcelona also has a night bus service (Nit Bus) which serves most of the city and its suburban area. You can identify the night buses with the letter N on the front (for example, N12). The night bus service usually starts around 10 pm and ends between 5 am – 6 am. They all stop at or depart from Barcelona’s Plaça de Catalunya.
Dual destination
Dual destination lines finish at two different destinations. This means that the place they start is the same, but some buses follow the complete route (longer), while others take shorter trajectories and the route ends a few stops earlier.
Double stops
This is a stop where two buses may simultaneously let passengers on and off. Double stops can shorten the time the buses are halted, and hence reduce the total time of the route.
A double stop consists of a central section, formed by one or two bus shelters, and two posts that indicate the two different stopping points. These posts indicate number 1 or 2 as applicable.
The first bus reaching the bus stop halts at stopping point 1, for as long as this is possible. If another bus arrives when stopping point 1 is occupied, this bus halts and lets on passengers at stopping point 2. The bus that halts at stopping point 2 will not halt again at stopping point 1 and continue its route, except in the case of blind passengers. If a blind passenger wants to get on this bus, it will halt at stopping point 1, even though it has already stopped at point 2.
Neighbourhood lines (bus de barri)
Which offer short local journeys within the neighbourhoods.
Bus on demand
This service seeks to make it easier for the city’s residents to move around certain neighbourhoods, taking into account their specific needs and the times at which they travel.
Suburban buses in Barcelona
The suburban bus service connects Barcelona with the rest of the municipalities in the metropolitan area: Badalona, Barcelona, Castelldefels, Cervelló, Cornellà de Llobregat, El Prat de Llobregat, Esplugues de Llobregat, Gavà, Les Botigues de Sitges, l’Hospitalet de Llobregat, Molins de Rei, Montcada I Reixac, Montgat, Sant Adrià de Besòs, Sant Boi de Llobregat, Sant Climent de Llobregat, Sant Feliu de Llobregat, Sant Joan Despí, Sant Just Desvern, Santa Coloma de Cervelló, Santa Coloma de Gramenet, Tiana and Viladecans.
Most suburban buses serving the municipalities around Barcelona are easily recognizable by their yellow color.
If the suburban bus is operated by TMB, you can use the TMB ticketing system, including integrated travel cards like T-casual, T-usual, and T-jove. However, be aware that not all TMB suburban buses allow card payments. It’s a good idea to carry a valid ticket or small cash, just in case contactless payment isn’t available.
To the Airport by bus
Aerobús
The Aerobús, the official shuttle bus service, connects Barcelona Airport T1 & T2 to Plaça España or Plaça de Catalunya in the city centre. You can either purchase tickets online beforehand or when you get on the bus, prices are €6,75 for a single or €11,65 for a return ticket.
TMB bus No.46
The TMB bus no.46 bus travels from the city centre, stopping first at T2 and then continuing on to T1. The big advantage of using this bus is that you don’t have to purchase a special ticket and you can use the T-Casual ticket.
Interurban and international buses in Barcelona
The Barcelona Nord Bus Station is the central hub for the arrival and departure of buses from the city of Barcelona to different destinations, both national and international.
At this station you will find many of the interurban bus companies that connect Barcelona with other municipalities in Catalonia such as: Moventis, Sagalés and Teisa.
Barcelona’s Bus Plans for the Future
Barcelona’s new Urban Mobility Plan (PMU) 2025 – 2030 aims to reduce car use and improve public transport, especially buses. The city wants 85% of all trips to be made by walking, cycling, or public transport. One big goal is to move 250,000 daily work trips from private cars to public transport like buses.
The plan includes making the bus network faster, more frequent, and easier to use – especially for work, school, and hospital trips. There will also be better night and weekend services, and more express and on-demand buses. Barcelona will add many more electric buses to cut pollution and make the city cleaner. The city hopes these changes will reduce traffic, lower pollution, and make travel safer and easier for everyone.
