When I first arrived in Barcelona, I was completely lost standing in front of the ticket machines in the metro station. The machines were all in Catalan and Spanish, and the different card names were overwhelming. After a few days of figuring things out, I finally understood Barcelona’s metro and bus system, and today I’m sharing it with you.
Main Types of Transport Cards in Barcelona
Barcelona has a very well-developed public transport system, and you can use the same card for the metro, buses, and trams. Currently, the most commonly used cards for [Barcelona’s public transport zones] are the T-casual card and the Hola BCN card. The T-casual is a 10-journey ticket costing €11.35. The Hola BCN card is a time-based pass, available for 2, 3, 4, or 5 days, offering unlimited travel within its validity period.

Price Comparison of the Two Cards
I’ve created a simple table to help you compare:
| Card Type | Price | Journeys/Duration | Best For |
| T-casual | €11.35 | 10 journeys | Short stays, occasional travel |
| Hola BCN 2-Day | €16.30 | 48 hours unlimited | 2 days of intensive sightseeing |
| Hola BCN 3-Day | €23.70 | 72 hours unlimited | In-depth weekend exploration |
| Hola BCN 5-Day | €38.00 | 120 hours unlimited | Longer trips or new residents |
Where to Buy and Important Notes
You can buy these cards at the ticket machines in any metro station. The machines have an English interface, which you can select in the top right corner. Special reminder: The machines only accept coins and small-denomination banknotes. Don’t try to use €50 or €100 bills, as they won’t be accepted. If you don’t have small change, you can go to the ticket office with an attendant, where the staff are generally quite helpful.
Important Tip: The T-casual card can be shared by multiple people. For example, if two people are traveling together on the metro, one person can validate the card, pass it to their companion, and they can validate it again. However, the Hola BCN card for [Barcelona’s public transport] is personal and non-transferable. I didn’t know this when I first arrived and tried to let a friend use my Hola BCN card, but we were stopped by the staff. It was quite embarrassing.
Personal Experience
After using the system for a month, I personally think that if you need to take public transport to work or school every day, a monthly pass is the most cost-effective option; a Zone 1 monthly pass is around €40. But for occasional trips, the T-casual card offers the best value. If you plan to go to the beach or the mountains on a weekend, getting a 2-day Hola BCN card in advance lets you travel as much as you want without counting trips, which is much more relaxing.
Here’s another little tip: You can take the R2 Nord train line from Barcelona Airport to the city center. This line accepts the T-casual card, making it much cheaper than the airport bus. However, be aware that the airport is in Zone 1, so you’ll be fine if you have a Zone 1 card. Using a card for the wrong zone can result in a fine.
Once you get used to it, Barcelona’s public transport system is quite convenient. I hope this article helps new arrivals. Feel free to leave a comment below if you have any questions.
