Spain and Portugal together make one of the most rewarding overland destinations in Europe: a peninsula with a dense high-speed rail network in Spain, a more relaxed pace in Portugal, stunning Atlantic and Mediterranean coastlines, and an interior that most visitors fly over rather than through. This guide covers the main rail and bus connections for a slow loop of the Iberian Peninsula, with the scenic detours that make the overland journey worth doing.
Getting to Iberia overland
The main overland entry from the rest of Europe is by train from France. The high-speed Paris to Barcelona service — see the Paris to Barcelona route guide — crosses the Pyrenees by tunnel in under 7 hours from Paris Gare de Lyon, arriving at Barcelona Sants. From Barcelona, AVE high-speed trains fan out across Spain; the peninsula is your starting point.
From Paris, there is also a direct overnight Trenhotel service to Madrid via the French border (though services on this corridor have changed over the years — check current availability), and connections via San Sebastián and Irún on the Atlantic side of the Pyrenees offer a more scenic entry. The Atlantic Pyrenean crossing is slower but gives you a glimpse of the Basque Country before you hit the Spanish high-speed network.
The Spanish high-speed network
Spain has one of the most extensive high-speed networks in Europe, radiating out from Madrid. Key journey times from Madrid:
- Barcelona: about 2h30 by AVE (reservation required).
- Seville: about 2h30 by AVE.
- Valencia: about 1h40 by AVE.
- Málaga: about 2h30 by AVE.
- Bilbao: about 5h by conventional train (the Basque region is not yet on the high-speed network).
Madrid is inevitably a hub — most cross-Spain journeys go through it or around it. Spend at least two nights: the Prado, the Reina Sofía, the Gran Vía and the Retiro park fill a day each. The city comes alive very late by Northern European standards; dinner before 9 pm is considered early.
Barcelona and the east coast
Barcelona deserves three or four nights and is most manageable if you pick a neighbourhood and slow down: the Gothic Quarter, Gràcia, the waterfront. The AVE to Valencia takes under two hours; from Valencia, the coast south to Alicante is covered by regional trains and the scenic Benidorm–Dénia section of the narrow-gauge TRAM Metropolità.
The coast railway south from Barcelona through Tarragona to Valencia — slower than the AVE but running right along the Mediterranean — is a worthwhile scenic choice if you are not in a hurry.
Andalucía: Seville, Granada and the south
Seville is one of the great slow-travel cities: the Alcázar, the barrios of Triana and Santa Cruz, and a tapas culture that requires you to eat standing at a bar counter. From Seville, Granada is about 3 hours by bus (the train is slower); Cádiz is an easy day-trip by regional train. The Alhambra in Granada requires advance booking — months in advance in high season — regardless of how you travel.
Málaga is a useful hub for the Costa del Sol and is connected to Madrid by AVE. From Algeciras, ferries cross to Ceuta (Spanish territory on the African coast) and to Tangier in Morocco — a natural extension of the overland route if you are continuing south.
Crossing into Portugal
The Spain–Portugal rail connection is less direct than you might hope. The main option is the Lusitania overnight train from Madrid to Lisbon — roughly 10–11 hours, with couchette and sleeper options. It is comfortable and saves an accommodation night. Daytime trains require changes and are slower.
Buses (Alsa and other operators) link Seville to Faro and Lisbon, and are often faster for cross-border journeys, particularly in the south. The Faro–Lagos section of the Algarve is served by regional trains; buses cover the more scenic cliff-top coastline.
Portugal: Lisbon, Porto and the north
Lisbon is a city for walking: hilly, tiled, full of miradouros (viewpoints) that reward getting lost. Allow three nights at minimum. Trams and funiculars cover the steeper hills; the commuter rail network reaches Sintra (about 40 minutes) and Cascais along the coast.
From Lisbon, Alfa Pendular and Intercidade trains run north to Porto in about 3–3h30 — no compulsory reservation on the Alfa Pendular, though booking is wise. Porto is compact, beautiful, and genuinely warm: the Ribeira waterfront, the port wine lodges across the Douro, and the azulejo-tiled São Bento station are the highlights. North of Porto, trains reach Viana do Castelo and the Minho coast before the border with Spain.
For a scenic return to Spain, the train from Porto to Vigo crosses the border at Valença–Tuy and continues to Santiago de Compostela in Galicia — one of the quieter cross-border rail connections on the peninsula. From Santiago, trains reach Madrid in about 4h30 by AVE.
A suggested loop
A practical slow-travel loop of Iberia from Barcelona might run: Barcelona → Madrid → Seville → Granada → Málaga → Lisbon → Porto → Santiago de Compostela → Bilbao → San Sebastián → back to France. This covers around 3,500 km by surface and takes a comfortable three to four weeks. If you want more time in Portugal — which most travellers who have been once say they wish they had taken — swap a few days of Spanish coast for the Alentejo wine country or the Douro Valley.
How long do you need?
- Madrid + Seville + Lisbon + Porto (rushed): 10–12 days.
- Comfortable loop with Granada and Barcelona: 3 weeks.
- Full Iberia including the north (Basque, Galicia) and Algarve: 4–5 weeks.
Practical notes
Spanish trains are punctual and comfortable. Portuguese trains are slightly older but perfectly reliable on main routes. Both countries are far more affordable than Northern Europe for food and accommodation. Heat in July and August in Andalucía and the Alentejo is intense — southern Spain and Portugal in midsummer can reach 40°C; an early start and a long afternoon rest is the local approach.
For those doing Iberia as part of a longer European overland — perhaps arriving from Paris and returning via the no-fly route — the peninsula connects naturally into the wider network.
Frequently asked questions
Can I travel between Spain and Portugal by train?
Yes, though options are more limited than within each country. The overnight Madrid–Lisbon train is the most useful connection; cross-border buses are often faster for journeys between Seville and Lisbon, or from Porto to Vigo in Spain.
Do I need reservations on Spanish trains?
Yes — all AVE and Avant high-speed services require a paid seat reservation, even with a rail pass. Buy these as early as you can; advance prices are considerably lower than walk-up fares.
What is the best way to get from France to Iberia by train?
The quickest is the direct Paris–Barcelona high-speed service (around 6h40). For an Atlantic crossing, change at Hendaye or Irún from a French train to a Spanish one — slower but more scenic through the Basque Country.
How expensive is travel in Spain and Portugal?
Both countries are well-priced compared to Western Europe, particularly Portugal. Accommodation, restaurant meals (the menú del día lunch in Spain is excellent value) and local transport are all affordable. Train reservations on AVE are not expensive if booked in advance.
