When to book: peak seasons, long weekends and prices

Key rules

• Peak periods: Semana Santa, August, Christmas and New Year, and puentes are the most expensive and busiest times.
• Price rise: Peak prices typically run 20–100% above off-peak, depending on the place.
• Puente days: Thursday, Friday, Sunday and Monday trains and flights sell out first around a long weekend.
• Minimum stays: Popular getaway spots often require 2–3 nights over a puente.

When prices and availability peak

Prices peak at four times of year: Semana Santa, August, the Christmas and New Year period, and the long weekends. Expect roughly 20–100% more than off-peak, depending on where you go.

• Semana Santa is Holy Week, the days around Easter. Cities often rise most.
• August, especially the whole month around the 15 August holiday. Beach and holiday destinations also rise sharply in July.
• Christmas and New Year.
• Puentes, the "bridge" long weekends: 1 May, 12 October (Hispanidad), and the December Constitution and Immaculate Conception holidays.

Dates move each year, and regional holidays differ. Check the calendar for your region and the year you travel.

Where each type of place gets expensive

Coastal and holiday spots are priciest in July and August. Cities tend to jump at Easter and on puentes, because locals leave for short breaks and visitors fill the hotels.

How a puente affects your trip

A puente cuts availability as well as raising prices. The worst days are the way out (Thursday or Friday) and the way back (Sunday or Monday). High-speed trains and cheap flights sell out first. Popular getaway spots often ask for a minimum stay of 2–3 nights.

If you can, travel on the days in the middle, or leave a day earlier or return a day later. The size of the increase varies by route and year.

How to time your booking

• Book trains, flights and lodging as early as you can for peak dates.
• Choose free-cancellation rates when you book early, so you can change plans without losing money.
• For a puente, book the departure and return days first, since they sell out first.
• Travelling just outside the peak weeks is usually much cheaper.

The booking calendar below shows when to book each type of trip. The comparison below helps you choose between train, coach and plane.

Train, coach and plane across Spain compared

Which one to pick

On the main routes from Madrid, the high-speed train is usually the best mix of time, price and comfort. Coaches are the cheapest but take about twice as long or more. Planes rarely save you time once you add the airport.

Typical times and prices

Prices are for standard adult one-way fares. They vary with the operator and how early you book.

Time

Flight times leave out the trip to the airport, check-in, security and boarding. Add those and the plane is often no faster than the train. The train also leaves from and arrives in the city centre.

Price and flexibility

• Train: The cheapest fares go to people who book early. Last-minute tickets cost far more. Renfe (including its low-cost brand Avlo), Ouigo and Iryo compete on Madrid-Barcelona, Madrid-Valencia and Madrid-Andalusia, so compare all of them. Renfe also runs the high-speed lines to Galicia.
• Coach: Usually the lowest price on every route. Alsa is the largest operator, and FlixBus runs a low-cost national network. In Madrid, coaches leave mainly from Estación Sur and Avenida de América, so check which one your ticket uses.
• Plane: Fares swing the most, from cheap to as much as a train ticket or more. Bags, seat choices and the trip to the airport can add to the bill.

Fare conditions differ by operator and ticket type. Before you pay, check whether you can change or cancel the ticket, and what it costs. The cheapest tickets are often the least flexible.

What to watch for

• Fares change constantly, so check the operators' own sites or apps for the current price.
• Operators add routes over time, so look for new services on your route.
• If your plans may shift, pay a little more for a ticket you can change.

Trip booking calendar: when to book each type of trip

When to book each part of a peak-week trip

• Book lodging for Semana Santa, August or Christmas: 3 to 6 months before your stay; earlier for paradores, rural houses and coastal apartments in popular places (earliest 180 days before planned arrival; recommended 120 days before planned arrival; latest 90 days before planned arrival)

• Choose free-cancellation rates when you book early: when you book lodging, so an early booking carries little risk

• Watch for train sales to open: about 2 to 3 months ahead for Renfe, and roughly 2 to 6 months ahead for Ouigo and Iryo (earliest 180 days before planned arrival; latest 60 days before planned arrival)

• Book flights for peak weeks: 2 to 3 months before travel for Semana Santa, August, Christmas and long weekends (earliest 90 days before planned arrival; recommended 75 days before planned arrival; latest 60 days before planned arrival)

• Book lodging for a long weekend (puente): 1 to 2 months before your stay (earliest 60 days before planned arrival; latest 30 days before planned arrival)

• Book flights outside peak weeks: 3 to 8 weeks before travel, with the best fares often 4 to 6 weeks out (earliest 56 days before planned arrival; recommended 35 days before planned arrival; latest 21 days before planned arrival)

• Book island flights for summer: earlier than other flights, because island routes sell out sooner in peak summer

• Avoid last-minute fares: in the final days before travel, when fares are usually the most expensive

Quick answers about travelling within Spain

Do I need photo ID to take a domestic train in Spain?

Yes, carry photo ID, because inspectors on board can ask for it to match your ticket name, even though there is usually no check at the gate. Your DNI, residence card or passport works. Discounted fares need the matching ID or card.

Which ID can foreign residents use on domestic flights?

Foreign residents can fly with a valid passport, an EU/EEA national ID card, or the Spanish residence card (TIE). Airlines may refuse boarding without valid ID. Island resident discounts need proof of residence, such as a certificate de empadronamiento (town hall residence certificate).

How much luggage can I take on a Renfe train?

On long-distance and AVE trains Renfe allows 3 pieces: two suitcases up to 85x55x35 cm and one hand bag up to 40x30x15 cm. Ouigo includes only one small bag of 27x36x17 cm and charges for larger ones. Iryo allows one large suitcase and one hand bag.

Will I pay a tourist tax at my hotel in Spain?

Only in some places, because Spain has no national tourist tax and regions or towns set their own. Catalonia, the Balearic Islands, parts of Galicia and Valencia charge it. It is usually a per-person, per-night fee added to your hotel bill, often capped at a number of nights, with children exempt below a certain age.

Must I show my passport or ID at hotel check-in?

Yes, hotels must collect identity details from every guest aged 14 and over before check-in and report them to the police. Expect to give your name, document number, nationality, date of birth, address and contact details. Bring your passport or ID card.
