Portugal

Portugal links big city, wine country, and Atlantic coast over short distances: Lisbon and Porto are only around 2 h 58 min apart by train, with the Algarve in the south a further roughly 3 h from Lisbon. Between the terraced vineyards of the Douro, historic university towns, and the limestone cliffs of the Algarve, a trip can easily be extended into Spain or Morocco.

What awaits travellers in Portugal?

In short

Portugal stretches from the terraced vineyards of the Alto Douro in the north to the limestone cliffs of the Algarve in the south. Most trips combine the capital Lisbon, the port city of Porto, and the Algarve coast; the Alfa Pendular train covers Lisbon to Porto in only around 2 h 58 min. Those continuing on reach the Douro Valley, the university town of Coimbra, or the rural Alentejo with its cork oak forests and wine estates.

The country has 17 UNESCO World Heritage Sites, from the monasteries of Alcobaça and Batalha to the University of Coimbra and Porto's historic centre. The Algarve, at the far south, with over 3,000 hours of sunshine a year, is especially popular for beach holidays, while the north is greener and rainier.

This page summarises regions, best time to visit, entry requirements for Swiss, German, and Austrian nationals, as well as health and safety (as of September 2026), along with guidance from the FDFA, the Federal Foreign Office, and the BMEIA.

What kind of destination is Portugal?

In short

Portugal is a small but varied country: the Atlantic coast, the green wine country of the north, historic university towns in the centre, and the dry steppe landscape of the Alentejo create a picture that extends far beyond Lisbon and the Algarve. The official language is Portuguese, shaped by the seafarers of the 15th and 16th centuries who opened trade routes to Africa, Asia, and South America.

The north around Porto and the Douro Valley lives off port wine: the vineyards along the Douro have been a UNESCO World Heritage Site since 2001 under the name Alto Douro Wine Region. Further south, the land grows drier; the Alentejo is defined by cork oaks, olive groves, and whitewashed villages, the Algarve by limestone cliffs and long sandy beaches.

Nazaré on the Silver Coast became world-famous for record waves: on 29 October 2020, German big-wave surfer Sebastian Steudtner rode a 26.21 m wave there, setting a Guinness World Record.

The capital Lisbon lies at the mouth of the Tagus, built on seven hills; from there, in the 15th and 16th centuries, caravels set out on the voyages of discovery that made Portugal one of Europe's first global maritime powers.

Which regions of Portugal are worth visiting?

In short

Most trips combine Lisbon with Sintra and Cascais, Porto with the Douro Valley, and the Algarve with its beaches. Travellers with more time add Coimbra and Aveiro in the Centro region, the quiet Alentejo, or the Atlantic islands of Madeira and the Azores, which are worlds of their own geographically and climatically.

Lisbon and surroundings

Lisbon lies on the Tagus and is known for tram line 28 running through the narrow lanes of Alfama. The Jerónimos Monastery and the Torre de Belém at the river mouth recall the voyages of discovery and have jointly been a UNESCO World Heritage Site since 1983.

Sintra

About 30 km northwest of Lisbon lies Sintra with its palaces: the colourful Palácio da Pena, the Moorish Castelo dos Mouros, and the Quinta da Regaleira. The cultural landscape of Sintra has been a UNESCO World Heritage Site since 1995.

Porto and the north

Porto lies on the Douro, whose historic centre, the Dom Luís I Bridge, and the Serra do Pilar Monastery have been a UNESCO World Heritage Site since 1996. In the Ribeira, colourful houses line the river, while across in Vila Nova de Gaia the port wine cellars are stored.

Douro Valley

From Porto, the Douro River flows through the Alto Douro Wine Region, added to the UNESCO World Heritage List as a cultural landscape in 2001. Terraced vineyards define the slopes; river cruises and the train along the Linha do Douro open up the region.

Algarve

The southernmost region is known for beaches such as Praia da Marinha and the Benagil sea cave, along with towns such as Faro, Lagos, Tavira, and the coastal town of Sagres at Europe's southwesternmost tip. Tavira has represented Portugal since 2013 on the UNESCO Intangible Cultural Heritage list for the “Mediterranean diet.”

Centro: Coimbra and Aveiro

The University of Coimbra, founded in 1290 and one of the oldest in Europe, has been a UNESCO World Heritage Site since 2013. Aveiro, around 1 h north by train, is known as “Portugal's Venice” for its canals and colourful moliceiro boats.

Alentejo

Southeast of Lisbon stretches the Alentejo, with cork oak forests, olive groves, and the wine town of Évora, whose old town has been a UNESCO World Heritage Site since 1986. The region is considered especially peaceful and is known for country estates, wine estates, and its dark starry skies.

Madeira and the Azores

About 1,000 km southwest of the mainland lies the volcanic island of Madeira with its laurel forest, Laurisilva, a UNESCO Natural World Heritage Site since 1999. The nine Azores islands, further out in the Atlantic, sit one time zone behind the mainland and are known for whale watching and the historic old town of Angra do Heroísmo on Terceira.

When is the best time to visit Portugal?

In short

Spring (March to May) and autumn (September/October) are best for city trips and hiking, with mild temperatures and less rain than in winter. The Algarve is warmest and driest from June to September, with highs often above 29 °C; the north around Porto stays wetter all year round.

According to the Federal Foreign Office and the FDFA, forest and bush fires occur regularly from spring through autumn, especially inland and in the north.

What do you need to enter Portugal?

In short

Portugal is part of the Schengen area: Swiss, German, and Austrian nationals do not need a visa for tourist stays of up to 90 days within any 180-day period; a valid passport or national ID card is sufficient (as of September 2026). The FDFA, the Federal Foreign Office, and the BMEIA remain the authoritative sources.

  • Switzerland: as a Schengen state, Switzerland does not separately check entry into Portugal; according to the FDFA a valid identity document is sufficient, though checks still take place at the EU's external border.
  • Germany: according to the Federal Foreign Office, a passport or national ID card is sufficient; a passport is recommended especially for return flights via the United Kingdom, which is no longer part of the EU.
  • Austria: according to the BMEIA, a valid passport or national ID card is sufficient for tourist entry; unaccompanied minors need a dated letter of consent from a parent or guardian.
  • Other nationalities: separate rules apply. Travellers without Schengen visa-free status need a Schengen visa; the Portuguese embassy or consulate in the home country provides information.

The Entry/Exit System (EES) applies at the Schengen external borders: travellers without an EU, EEA, or Swiss passport have their fingerprints and a facial image taken on first entry. The online travel authorisation system ETIAS is also planned for visa-exempt third-country nationals; whether and from when it applies should be checked with the EU authorities before the trip.

The current guidance from the FDFA, the Federal Foreign Office, and the BMEIA at the time of travel is always authoritative.

Which vaccinations and health precautions do you need for Portugal?

In short

No vaccination is required for entry. healthytravel.ch recommends the standard vaccinations under the Swiss immunisation schedule, plus hepatitis A for travellers visiting relatives or acquaintances in remote rural areas or travelling under simple hygienic conditions. Malaria does not occur in Portugal.

The CDC lists up-to-date routine vaccinations (MMR, DTaP, polio) as the baseline for all travellers, plus hepatitis B for unvaccinated people under 60 on longer stays.

According to healthytravel.ch, there is some dengue fever risk on Madeira; protection against mosquito bites during the day is recommended. Medical care in the country is good, though less dense in the rural Alentejo and on the islands than in Lisbon and Porto.

For EU/EEA travellers, the European Health Insurance Card applies; the BMEIA nonetheless recommends supplementary insurance for Austrians, since not all treatments are covered.

How safe is Portugal for travellers?

In short

Portugal is considered a safe travel country; check the current situation with the FDFA, the Federal Foreign Office and the BMEIA. The greatest risk for travellers is petty crime such as pickpocketing in Lisbon and Porto, along with seasonal forest and bush fires and occasional earthquakes, mainly on Madeira and the Azores.

According to the Federal Foreign Office, pickpocketing and bag snatching are more frequent in busy spots such as Praça do Comércio, Rua Augusta, Castelo de São Jorge, as well as on the historic trams and at stations in both cities; in the nightlife districts of Bairro Alto and Cais do Sodré, the embassy advises particular caution in the evening and at night.

Along the Atlantic coast, the BMEIA warns of strong undercurrents and high waves; the coloured flags on beaches should always be observed. Forest fires occur mainly in the centre and north during the summer months, according to the Federal Foreign Office.

How do you travel to Portugal and get around the country?

In short

International flights land in Lisbon (LIS), Porto (OPO), or Faro (FAO); Lisbon, according to FlightConnections, has 155 nonstop destinations in 52 countries, including connections to São Paulo, Rio de Janeiro, New York, Toronto, and Dubai. Between the cities, the Alfa Pendular train runs, covering Lisbon to Porto in around 2 h 58 min.

Lisbon – ÉvoraTrain/busaround 1 h 30 min
Lisbon – SintraTrainaround 40 min

Porto (OPO), according to FlightConnections, has nonstop flights to 136 destinations in 31 countries, including São Paulo as the only intercontinental long-haul route with TAP Portugal; Faro (FAO) connects 89 destinations in 23 countries, mostly in Europe, with seasonal service to Toronto as well.

All three airports lie close to the city centres; from Lisbon airport, the metro takes around 20 to 30 min into the city centre. Rental cars are common in the Algarve and the Alentejo, but rather a hindrance in Lisbon and Porto with their narrow old-town streets; both cities have metro and tram networks.

Hikers use the roughly 400 km of trails of the Rota Vicentina along the southwest coast between the Alentejo and the Algarve, or sections of the Caminho Português, the Portuguese Way of St. James, from Lisbon via Porto to Santiago de Compostela in Spain.

What money do you need in Portugal, and how do you pay?

In short

The national currency is the euro; card payment is used almost everywhere, including through the nationwide Multibanco ATM network. Tipping is not mandatory; 5 to 10% in restaurants is customary if service is not already included in the bill.

Multibanco ATMs stand on practically every corner and allow not only cash withdrawals but also bill payments and top-ups via the MB Way system; fees are usually lower than at bureaux de change. Credit cards (Visa, Mastercard, and American Express is also widely accepted) are accepted almost everywhere.

In taxis, according to the tourism authority, people usually round up to the nearest euro or give 5 to 10%. At markets and small village shops, especially in the Alentejo, cash is still in demand.

Anyone arriving from a non-euro country such as Switzerland pays the lowest card fees with a travel credit card without foreign currency surcharges; exchanging money directly at the airport is usually more expensive than at an ATM.

Where is the best place to stay in Portugal?

In short

In Lisbon, most accommodation is in the Baixa, Chiado, or Belém districts; in Porto, around the Ribeira or in Vila Nova de Gaia near the port wine cellars. In the Algarve, hotels are concentrated in the coastal towns of Albufeira, Lagos, Vilamoura, and Tavira.

Historic manor houses and monasteries have in many places been converted into pousadas, for example in Évora or Óbidos; in the Douro Valley, people often stay directly on a wine estate (quinta) with a view over the terraces.

In the Alentejo, country estates (herdades) are common, often with their own olive groves; on Madeira and the Azores, much of the accommodation is in the main towns of Funchal and Ponta Delgada respectively.

What do people eat in Portugal?

In short

Bacalhau, dried and salted cod, is considered the national dish with reportedly hundreds of preparation methods; add to that grilled sardines, shellfish dishes such as the Algarve's cataplana, and the caramelised puff pastry tarts pastéis de nata. National drinks range from port wine to vinho verde to ginjinha cherry liqueur.

Pastéis de Belém in Lisbon has been baking to the same original recipe from the neighbouring Jerónimos Monastery since 1837. Food is heartier in the north: francesinha, a layered sandwich with a beer-and-tomato sauce, is a Porto speciality.

In 2013, the Mediterranean diet was recognised as UNESCO Intangible Cultural Heritage, represented for Portugal by the Algarve town of Tavira; the cuisine relies on olive oil, fish, vegetables, and the shared table.

What culture and festivals shape Portugal?

In short

Fado, a melancholic sung poetry accompanied by the Portuguese guitar, was recognised as UNESCO Intangible Cultural Heritage in 2011 and is performed live mainly in Lisbon's Alfama, Mouraria, and Bairro Alto districts. The largest folk festival is the Santos Populares in June, when Lisbon and Porto celebrate Saints Anthony, John, and Peter with street parties.

The University of Coimbra, founded in 1290, still shapes the city today with its black student capes and its own fado tradition; its historic core has been a UNESCO World Heritage Site since 2013.

In the Douro Valley, the grape harvest usually ends in September with festivals around the vintage; in the Algarve, the carnival (in February or March, depending on the date of Easter), with parades in Loulé, shapes the pre-spring calendar.

Which experiences are especially worthwhile in Portugal?

In short

Highlights include a boat or kayak tour along the limestone coast of the Algarve to the Benagil sea cave, a trip through the terraced vineyards of the Douro Valley, fado evenings in Lisbon's Alfama, and, for the daring, the big-wave spectacle off Nazaré in winter.

Douro Valley

From Porto, river cruises and excursion trains run along the Linha do Douro through the wine landscape protected as a World Heritage Site since 2001; many wine estates (quintas) offer tastings and tours.

Algarve coast

Boat and kayak tours from Portimão or Lagos reach the grottoes and rock formations near Benagil and Ponta da Piedade; the Ria Formosa near Faro and Tavira is a wetland with boardwalks and birdwatching.

Rota Vicentina and the Way of St. James

The Fishermen's Trail of the Rota Vicentina follows the steep coast between the Alentejo and the Algarve on unspoiled paths; the Portuguese Way of St. James (Caminho Português) links Lisbon via Porto to Santiago de Compostela in Spain.

Nazaré

From October to March, giant waves at Praia do Norte in Nazaré draw big-wave surfers; in 2020, Sebastian Steudtner set a Guinness World Record there with a 26.21 m wave. The lighthouse above the beach offers a safe vantage point to watch the spectacle.

  • Sintra: the palace route by bus 434 between the train station, Castelo dos Mouros, and Palácio da Pena.
  • Lisbon: the Santa Justa Lift and viewpoints (miradouros) over the rooftops of the city.
  • Porto: a river cruise under the six Douro bridges, plus a visit to the port wine cellars in Vila Nova de Gaia.
  • Coimbra: a visit to the historic university library, the Biblioteca Joanina.

How do you travel responsibly in Portugal?

In short

Forest and bush fires are a real risk during the summer months; open fires and smoking in forests are then prohibited. Anyone visiting Nazaré, Sintra, or the Algarve in high season eases pressure on the infrastructure by travelling outside the summer holidays or during the week.

  • Watch the flags on beaches along the Atlantic coast and do not swim against the current.
  • Avoid entering forest areas with open flames during the dry season; heed regional civil protection warnings.
  • On trails such as the Rota Vicentina, stay on marked routes to protect the coastal vegetation.
  • In the Douro Valley, visit small family wine estates as well as the large producers; it supports the local economy.

Which countries combine well with Portugal?

In short

Spain to the east is the most obvious choice, sharing Portugal's only land border; train and bus connections run, for example, from Lisbon to Seville or from Porto to Vigo in Galicia. A direct flight from Lisbon or Faro also easily connects to Morocco on the other side of the Strait of Gibraltar.

The Caminho Português, the Portuguese Way of St. James, leads on foot from Lisbon or Porto across the border into Galicia and ends in Santiago de Compostela.

Those wanting to travel further will find numerous nonstop connections from Lisbon and Porto to Morocco, for example to Marrakesh, and to the Canary Islands; both are a similar flight time away as many Spanish destinations.

Sources: FlightConnections

Who is Portugal a good fit for, and who is it less suited to?

In short

Portugal suits travellers who want to combine cities, culture, wine, and coast over short distances, as well as families and hikers along the coastal trails. It is less suited to anyone seeking high mountains or rainforest on a trip; the country lacks the geographic scale for that.

Portugal works well for shorter trips of one to two weeks, since the distances are small: from Lisbon, Porto, the Algarve, and even Madrid in Spain are within a few hours by train or plane.

Anyone who only wants to swim in the Algarve should avoid the heavily touristed coastal towns such as Albufeira in high season, when they become considerably busier than the Alentejo or the west coast.

Worth combining

Clarity before you go

Frequently asked questions

The key questions about Portugal, answered.

Do Swiss nationals need a visa for Portugal?

No. Portugal is a Schengen member, and for tourist stays of up to 90 days within any 180-day period, a valid passport or national ID card is sufficient (as of September 2026). The current guidance from the FDFA is always authoritative.

How do you get from Lisbon to Porto?

Fastest by the Alfa Pendular train run by Comboios de Portugal, taking around 2 h 58 min, with several connections daily in each direction. Intercity trains are somewhat slower and cheaper, at around 3 h 23 min.

Is Portugal suitable for families?

Yes, especially the Algarve with its sheltered coves and short distances between beach, hotel, and excursion destinations such as the Zoomarine theme park. Lisbon and Porto are compact enough to explore on foot or by tram, even with children.

When is the rainy season in Portugal?

Most rain falls from November to January, especially in the north around Porto. In the Algarve and in Lisbon, little rain falls in summer from June to August, but the wildfire risk rises there instead.

How safe is Lisbon for tourists?

Generally safe, with petty crime as the main risk: according to the Federal Foreign Office, pickpocketing is more common around Praça do Comércio, Rua Augusta, and tram line 28. Keep valuables close to the body and take particular care at night in Bairro Alto and Cais do Sodré.

What is the best time for the Algarve?

June to September for warm sea water and the highest temperatures, often above 29 °C, with the most visitors in July and August. May, September, and October are quieter and milder, with a similar number of sunshine hours.

Do you need a vaccination for Portugal?

None is mandatory. The standard vaccinations under the Swiss immunisation schedule are recommended, plus hepatitis A for travel to rural areas or under simpler hygienic conditions. Malaria does not occur in Portugal.

What is fado?

A melancholic sung poetry accompanied by the Portuguese guitar, recognised as UNESCO Cultural Heritage since 2011. It is performed live mainly in small venues in Lisbon's Alfama, Mouraria, and Bairro Alto districts.

How do you get to the Benagil sea cave?

By boat or kayak tour from Portimão, Armação de Pêra, or Carvoeiro; the cave is not accessible on foot. The tours usually last one to two hours and can be booked on site at the marinas.

Porto or Lisbon: which city is more worthwhile?

The two complement each other more than requiring a choice: Lisbon is larger, hillier, and closer to Sintra and the coast, while Porto is more compact and sits directly on the Douro with the port wine cellars of Vila Nova de Gaia. By train they are around 2 h 58 min apart.

When are the biggest waves at Nazaré?

The main season for giant waves at Praia do Norte runs between October and March, when Atlantic swell meets the underwater canyon. In 2020, Sebastian Steudtner set a Guinness World Record there with a 26.21 m wave.

Is tipping customary in Portugal?

Not mandatory, but common: 5 to 10% in restaurants if service is not already included in the bill, and rounding up to the nearest euro in taxis.

How many days do you need for Portugal?

For Lisbon, Sintra, and the Algarve, 7 to 8 days are enough; anyone adding Porto and the Douro Valley should plan for 10 to 14 days. The short train and flight times within the country also allow for spontaneous extensions.

Do Madeira and the Azores belong to Portugal?

Yes, both archipelagos are autonomous regions of Portugal with their own regional government. The Azores are one hour behind the mainland, while Madeira shares the same time zone.

What language is spoken in Portugal?

The official language is Portuguese. In tourist areas such as Lisbon, Porto, and the Algarve, English is generally well understood, less consistently so in the rural Alentejo and Centro.

How do you get from Porto to the Douro Valley?

By train on the Linha do Douro along the river, by car in around 1 to 1.5 hours depending on the destination, or by river cruise directly from Porto. Many wine estates (quintas) also offer a pickup service.
