Portugal is a natural fit for slow travel. It is compact enough to cover thoroughly without flying, its rail network connects the main towns in comfortable style, and the country's pace of life rewards those who linger rather than rush. Whether you are arriving overland from Spain, arriving by ferry from the UK, or simply moving around once you are there, this guide covers how to do it — and why doing it slowly makes Portugal better.
Getting to Portugal without flying
Portugal sits at the western tip of continental Europe, which makes it the end of the line for rail travellers crossing the continent. The main overland routes from the rest of Europe funnel through Spain:
- From Madrid: the Lusitânia Comboio Hotel — a classic overnight sleeper train — links Madrid Chamartín with Lisbon Santa Apolónia, taking around 10–11 hours. It is not the fastest route but it is one of the most enjoyable, covering the distance while you sleep and delivering you to central Lisbon in the morning.
- From Madrid by day: a combination of Renfe trains to the border and Portuguese CP trains onward is possible, though it typically requires a change and adds journey time compared to the sleeper.
- From the UK: the classic route is Eurostar to Paris, then TGV to Madrid or another interchange, then onward to Lisbon or Porto — typically a two-day journey. Some travellers enjoy the rhythm of it, breaking at San Sebastián or Madrid. For a deeper discussion of the options, see our guide to flightless travel in Europe.
Coaches (FlixBus and Alsa among others) also serve Portugal from Spanish cities, typically at lower fares but longer journey times.
Arriving in Lisbon
Lisbon is the natural starting point for most visitors. Santa Apolónia station, the terminus for international trains, is just east of the historic Alfama district — a gentle walk or a short tram ride from the centre. Oriente station, further east, handles some long-distance and suburban services and is also the main coach terminal.
Lisbon rewards slow exploration. The Alfama is best walked early morning before the crowds arrive; the tram 28 route through the old hills is iconic but busy. The Belém district to the west, with the Jerónimos Monastery and the Tower of Belém, is an easy train ride from Cais do Sodré. Sintra — a town of fairy-tale palaces in the hills — is a 40-minute suburban train ride from Rossio station and a natural day trip.
Lisbon to Porto by train
The Alfa Pendular — Portugal's tilting high-speed train — connects Lisbon Oriente with Porto Campanhã in about 2h45 to 3 hours, running several times a day. It is comfortable, reliable, and offers good views of the Douro estuary as it approaches Porto. Advance booking is recommended to secure the best fares; reservations are required on this service.
For a slower, more scenic version, the intercity services and regional trains take longer but stop at smaller towns along the Atlantic coast. Coimbra, Portugal's historic university city, is a natural midpoint stop — Coimbra B is the main station, connected to Coimbra A in the centre by a shuttle. Worth a half-day at minimum.
Porto and the north
Porto is one of Europe's most rewarding city destinations: its historic core (a UNESCO World Heritage Site), the Douro waterfront, the wine lodges of Vila Nova de Gaia across the river, and a food scene that has flourished in recent years. São Bento station, the central city terminus, is decorated with azulejo tile panels depicting Portuguese history — it functions as both a railway station and an artwork.
From Porto, the Douro Valley is an unmissable excursion. The Douro line railway follows the river east through steep terraced vineyards to Régua, Peso da Régua, and onward to Pocinho — a journey of around three to four hours to the end of the line. It is regularly cited as one of the most beautiful train journeys in Europe, and for once the superlative is earned. Some visitors combine the outward journey by train with a return by boat down the river.
Further north, Viana do Castelo on the coast is a handsome riverside town reachable by train from Porto; the Minho region along the Spanish border is green and quiet.
South to the Alentejo and Algarve
The Alentejo — the vast inland plain south of Lisbon, dotted with cork oak forests, white hilltop villages and ancient standing stones — is harder to explore without a car, but Évora is connected to Lisbon by train (around 1h30 on the fastest service). It is a fine base for absorbing the region's unhurried atmosphere.
The Algarve is reached from Lisbon by the Alfa Pendular or intercity service to Faro (around 3–3h30), and from Faro the regional rail line runs west to Lagos and east to Vila Real de Santo António on the Spanish border. The Algarve's towns are connected to each other by this coastal railway, which makes car-free travel along the coast entirely feasible — though some beaches require a bus or taxi from the nearest station.
Island ferries: Setúbal, Sesimbra and the Sado estuary
Ferries are part of the everyday transport fabric around Lisbon. The most useful for visitors is the Cacilheiro ferry across the Tagus to Cacilhas, departing from Cais do Sodré and offering superb views of Lisbon and the Ponte 25 de Abril bridge. From Cacilhas, buses reach Almada and the beaches of the Costa da Caparica. The Setúbal estuary and the Troia peninsula are similarly accessible by ferry from Setúbal town.
Moving around: practical logistics
Portugal's rail operator is Comboios de Portugal (CP). Tickets can be purchased online, at station machines, or at counters. The network covers the main towns and cities well but thins out considerably in rural areas — the Alentejo in particular has limited rail access. For the gaps, Rede Expressos is the main long-distance coach network, and local operators fill in regional routes.
Urban transport in Lisbon and Porto is good — both cities have metro systems, trams and bus networks. Porto also has a tram line to the coast and a funicular system. The Viva Viagem rechargeable card in Lisbon and the Andante card in Porto simplify ticket-buying across different modes.
For a comparison of rail passes versus point-to-point tickets in Portugal and across Europe, the Interrail vs Eurail guide is useful, particularly for visitors combining Portugal with other European countries.
When to visit and how long to allow
Portugal's climate is among the mildest in Europe. Spring (April–May) and autumn (September–October) are ideal: warm, not crowded, and the light is exceptional. Summer is busy, particularly the Algarve in July and August. Winter is mild and quiet — Lisbon and Porto are genuinely pleasant even in January, though the north can be rainy.
A sensible slow itinerary might allocate three or four days each in Lisbon and Porto, two days in the Douro Valley, and a few days in the Algarve. Two to three weeks works well without feeling rushed. If you are entering from Spain, the most direct routing is via Madrid and the Lusitânia overnight.
Frequently asked questions
Can I get to Portugal from the UK without flying?
Yes. The standard route is Eurostar to Paris, then TGV or high-speed train to Madrid (or via another change), then onward to Lisbon or Porto by overnight sleeper or day train. The total journey takes around 24–30 hours depending on connections, and many travellers spread it over two days with a stop in Spain.
Is the overnight train from Madrid to Lisbon worth taking?
The Lusitânia Comboio Hotel is a genuine sleeper train with compartments and couchettes, and it delivers you to central Lisbon without using the day. Many travellers find it a pleasant and practical way to cross the border. Fares and availability vary — book in advance.
Do I need a car to see Portugal properly?
Not if you focus on the main cities and coastal towns, which are well served by train and bus. A car helps enormously in the Alentejo and the interior. For a car-free trip, Lisbon, Porto, the Douro Valley by train, Coimbra and the Algarve coast are all excellent.
How long does the Douro Valley train journey take?
From Porto Campanhã to Pocinho at the end of the Douro line is around three to four hours, depending on the service. The most scenic section is roughly from Régua eastward. A return trip with time at Régua or Pinhão can be done comfortably in a day from Porto.
