Moving around Spain costs least when you book one long train or bus leg early, then use a multi-trip ticket inside each city and fit the paid sights around the free hours. This page is about that side of the budget: getting between and within places, and what you pay once you arrive at a museum door.

Should you take the train or the bus between Spanish cities?

Take the high-speed train when you can book several weeks ahead, and the bus when there is no direct rail line or the train fare is high on your date. Fares on the fast trains behave like airline fares: the earliest seats are cheapest and the price climbs as the train fills.

Compare the same day on both. On busy corridors the low-cost trains often undercut the bus, while on routes that need a change or run through smaller towns, the bus is usually quicker and simpler. In smaller towns and mountain areas, a bus is often the only public option. Buy bus tickets through the operator’s own website or app, or at the station, and avoid resellers that add a fee on top.

For a trip with several stops, price each leg separately instead of looking for one pass.

What does a low-cost train really cost on Madrid to Barcelona?

The lowest published fare is Ouigo’s, from 9 euros, and the operator also advertises tickets from 19 euros on this route. Expect a journey of roughly three hours, depending on the train and its stops.

Ouigo’s five daily departures from Madrid Atocha are at 06:22, 09:31, 13:42, 16:22 and 20:10. The cheapest fares tend to sit on the least convenient times, so check the early and late trains first, then decide whether a shorter night in a hotel is worth the saving. Renfe’s Avlo and Iryo run the same corridor: look at their own sites for the same date before paying, because the cheapest operator changes by day.

Budget for extras. Low-cost operators charge for larger bags and for seat choice, and the final price at checkout is the one to compare, not the headline fare.

Which city ticket is cheapest in Madrid and Barcelona?

A 10-trip ticket beats singles in both cities, by a wide margin in Barcelona. In Barcelona the T-casual costs 13 euros for 10 trips in zone 1, which is 1.30 euros a ride against 2.90 euros for a single on metro, bus or the Montjuïc funicular. In Madrid, the 10-trip Metrobús ticket for zone A costs 7.30 euros, or 0.73 euros a ride, while a single metro ride costs between 1.50 and 2.00 euros depending on the number of stations.

Airports are the exception in both cities. In Barcelona, the metro L9 Sud airport stations need the 5.90 euro Aeroport ticket, because the T-casual is not valid there. Madrid adds a 3 euro supplement on top of a single or Metrobús ride to the airport station.

If you arrive and leave within one day, Barcelona’s T-dia is worth a look. It costs from 12 euros for 24 hours and includes one airport journey in each direction. It only pays off if you really use the 24 hours: four single rides come to 11.60 euros, so from the fifth ride it beats singles.

Seville, Valencia and Granada are compact. In many cases a day on foot covers what you came to see, so skip the transport ticket there until you need it.

Is a city tourist card worth buying in Spain?

Usually not, unless you ride a lot of public transport. The Hola Barcelona Travel Card starts at 12.50 euros (11.25 euros online) for one day and runs up to five days, and it includes the airport metro. It is a transport ticket, not a sightseeing pass, so it only beats a T-casual if you make many trips a day or stay several days.

For museums, add up the sights you actually want. Prado and Reina Sofía both have free evening slots, and the Picasso Museum and MNAC have free times too. Our Spain money-saving guide lists those slots, so you can plan without buying a card.

Which sights are free or cheaper, and which days should you avoid?

Plan around weekday patterns: the free slots exist, but so do closing days. The Thyssen-Bornemisza in Madrid is free on Mondays from 12:00 to 16:00 with no ticket needed. In Barcelona, the Picasso Museum and MNAC are both closed on Mondays.

Full prices help you judge whether a free slot is worth the queue. The Prado costs 15 euros, the Reina Sofía 12 euros and the Thyssen-Bornemisza 14 euros. In Barcelona the Picasso Museum is 12 euros online and 13 euros at the desk, and the MNAC is 12 euros for a ticket valid for two days within a month, including the rooftop terrace. The Alhambra’s general ticket is 22.27 euros, with night visits to the Nasrid Palaces at 12.73 euros. Buy it only on the official Patronato site, bring your passport or ID card, and enter the palaces in the time slot printed on the ticket.

Check closing days before you travel: the Prado is shut on 1 January, 1 May and 25 December, and the Reina Sofía is closed on Tuesdays. Free tickets for the Reina Sofía can be booked online, and the Picasso Museum requires a reservation for its free slots, released four days ahead at 10:00.

What does a day of transport and sights cost?

A free-slot day costs close to nothing in entry fees, and a paid two-museum day costs about 24 to 27 euros plus transport. Here is the arithmetic, using the prices above and leaving food and accommodation out.

A Madrid museum day with four metro rides on a 10-trip ticket is about 2.92 euros in transport. Visit the Thyssen free on Monday, or the Prado in its free evening slot, and your total stays under 3 euros. Pay for the Prado and the Reina Sofía instead and entry alone is 27 euros.

A Barcelona day with four rides on the T-casual is 5.20 euros. Use the free Thursday afternoon at the Picasso Museum and that is the whole bill; pay for the Picasso Museum and MNAC and it is 24 euros plus transport. Because the MNAC ticket stays valid for a second day, you can split it across two days.
