A practical 8-day Portugal by train itinerary from Lisbon to the Douro Valley, taking in Sintra, Coimbra and Porto plus the country's most scenic rail line.
Portugal is one of the easiest countries in Europe to explore without a car, and this Portugal by train itinerary proves it. Over about eight days it runs south to north, from the trams of Lisbon to the terraced vineyards of the Douro, using nothing but scheduled trains. You get two great cities, a fairytale hill town, the country's oldest university and one of the most scenic railways on the continent, all without touching a steering wheel.
Portugal's main line links Lisbon, Coimbra and Porto with fast, comfortable Alfa Pendular trains, and the branch lines fill in the rest. Sintra is a short suburban hop from Lisbon, and the Linha do Douro carries you from Porto straight into the wine country. No leg is long enough to swallow a day, and every city on the route is walkable once you step off the platform.
This is a one-way trip rather than a loop. Finishing in the Douro keeps the journey efficient, and Porto is only about two and a half hours back by train when it is time to fly home.
Start with two nights in the capital. Lisbon rewards slow walking. Ride tram 28 through the tight lanes of Alfama, climb to the Castelo de Sao Jorge for the view over the river, and make time for Belem, where the pasteis de nata are still warm from the oven. The city's rail and metro links also make it the natural base for the day in Sintra that follows.
Sintra sits just 40 minutes west by train, in a pocket of misty wooded hills. The headline is Pena Palace, a riot of red and yellow towers, but the Moorish Castle and the gardens of Quinta da Regaleira are just as memorable. Staying the night lets you reach the palace soon after it opens, before the day-trippers arrive on the same train you would otherwise be fighting for.
Coimbra breaks the journey north at the perfect halfway point. Portugal's oldest university crowns the hill above the Mondego river, and its baroque Biblioteca Joanina is one of the most beautiful libraries in the world. In the evening, hear Coimbra fado, a sterner, male-voiced cousin of the Lisbon style, sung by performers in dark student capes.
White chalk cliffs, a Norman conquest battlefield, cobblestoned medieval streets and a seaside city that refuses to be ordinary: this East Sussex road trip itinerary covers it all in seven days.
Porto is the trip's northern anchor and the gateway to the Douro, so give it two nights. Wander the steep Ribeira quarter, step inside Sao Bento station to see its blue azulejo tile panels, and cross the Dom Luis bridge to the port lodges of Vila Nova de Gaia, where the wine is aged in riverside cellars. It is also where the best part of this Portugal by train itinerary begins.
Save the Linha do Douro for last. The line leaves Porto's Sao Bento station and follows the river east through 26 tunnels into a UNESCO-listed landscape of hand-built vineyard terraces. Sit on the right for the best views. Get off at Pinhao, whose tiled 1937 station opens straight onto working quintas, and stay the night for a Port tasting, a slow river cruise and a quiet evening once the day crowds have left.
Aim for spring or early autumn, roughly April to June or September to October. The weather is warm without the harsh midsummer heat inland, and a September visit lines up with the start of the Douro grape harvest. The cities are pleasant year-round, but the vineyards are at their best in these shoulder months.
Reserve seats for the Alfa Pendular legs to Coimbra and Porto in advance, especially in summer. The Sintra and Douro trains carry no reservations, so you can simply buy on the day at the station or online at cp.pt. Keep luggage light, because most of these stations involve stairs and a short walk at the other end, and the cities reward travellers who can move easily on foot.
If you want a relaxed, scenic week that still feels varied, this is one of the best ways to see Portugal. The cities change character at every stop, the food and wine improve as you head north, and the finale on the Douro Line is the kind of train ride people plan whole trips around. For a Portugal by train itinerary that never needs a car, this is the version I would book.
