Tour the Jerónimos Monastery in Belém
The Jerónimos Monastery is the high point of Manueline architecture, the ornate style of Portugal's age of discoveries, and a UNESCO World Heritage Site since 1983. King Manuel I founded it beside the Tagus, and building began in 1501 and went on for about a century, paid for largely by a tax on trade with Africa and the East. Start at João de Castilho's carved south portal, then step into the church, where the wide transept vault stands without a single supporting column. Near the entrance lie the tombs of Vasco da Gama, who sailed for India in 1497, and the poet Luís de Camões, while Manuel I and his son João III rest in the main chapel.
Tip: Buy your ticket on the official online ticket office before you go, since tickets often sell out and can't then be bought on the day, and remember the monastery is closed on Mondays.

Explore Pena Palace in the Sintra hills
Pena Palace crowns a summit of the Sintra hills, a colorful, castle-like palace that Parques de Sintra calls the pinnacle of Romanticism in Portugal. It was the creation of King Ferdinand II, the King-Artist, in the 19th century, and it mixes Manueline and Moorish styles. Around it, winding paths run through a park of dense woodland with more than 500 species of trees from around the world, and the hills are often veiled in mist. To get there, take a Sintra line train from Rossio, Oriente or Entrecampos in Lisbon, then Scotturb bus 434 from Sintra station. Private cars are not allowed up to the palace, so come by bus or on the walking trails.
Tip: Palace tickets are sold for a set date and entry time, so book online to skip the ticket queue, and add the small shuttle if you'd rather not walk the steep road from the park entrance to the palace.

Climb through Alfama to São Jorge Castle
Alfama is Lisbon's oldest neighborhood, a tangle of cobbled lanes, alleys and steep climbs that is best explored slowly on foot. Start at the Sé, the cathedral dating from 1147, where you can see its treasury and the Roman ruins found beneath it. Keep climbing to the Miradouro de Santa Luzia for the view over Alfama's rooftops to the Tagus, then on to São Jorge Castle at the top. Built in the mid-11th century, the castle keeps eleven towers from the Moorish period, and steps up the walls let you walk the ramparts around its whole perimeter, with views over the city from every side. After dark, Alfama's restaurants and fado houses fill the lanes below.
Tip: Buy castle tickets on the castle's own website or at its ticket office, since it warns that no other online seller is authorized, and wear comfortable shoes for Alfama's steep lanes.

Ride the yellow No. 28 tram across old Lisbon
The No. 28 is one of Lisbon's symbols, a small yellow tram that runs between Graça and Prazeres through some of the city's prettiest historic and residential quarters. Along the way it slips between old neighborhoods, passes palaces and the cathedral, crosses the Baixa, climbs to Chiado and Estrela, and ends in Campo de Ourique. Open the window and watch tiled facades, sudden climbs, viewpoints and squares go by. You can hop off to see a sight along the way and catch the next tram on the same route. Rides are included in the Lisboa Card, which covers unlimited trams, buses, metro and trains for 24, 48 or 72 hours.
Tip: Keep your bag closed and in front of you, since the UK government warns that thieves work in teams on public transport and at crowded tram stops.

Wander Porto's Ribeira and cruise under its bridges
Ribeira is Porto's riverside quarter, where colorful houses, washing hung out in the sun and narrow streets run down to the Douro. It belongs to Porto's historic center, listed by UNESCO in 1996, and the tourism board notes that Prince Henry the Navigator set sail from here for the conquest of Ceuta. Wander the lanes for an hour or two, then take a bridges cruise, which sails along the Douro past the city's six bridges and shows both banks, Porto and Vila Nova de Gaia, from the water. Back on land, Ribeira has a wide choice of restaurants and bars, a good place to try a francesinha, tripe Porto-style or Gomes de Sá codfish.
Tip: If you buy a Porto.CARD, check its list before booking, since the tourism board says it gives discounts on some bridge cruises.

Taste port in Vila Nova de Gaia's cellars
Port wine comes from grapes grown on the terraced hillsides of the Douro Valley, the oldest demarcated wine region in the world, and it ends its journey at the river mouth, in the lodges of Vila Nova de Gaia where it is aged. The cellars line the Gaia bank of the Douro, facing Ribeira, and a visit with a tasting is the classic way to get to know the wine. On the river you can still see rabelo boats, the vessels that once carried the wine down from the quintas before dams made the Douro navigable. From Ribeira, walk across the lower deck of the Dom Luís I Bridge, and you are among the cellars in a few minutes.
Tip: Porto.CARD holders get a discount on admission to the cellars, so check the card's list before you choose a lodge.

Walk both decks of the Dom Luís I Bridge
The Dom Luís I Bridge, also written Luiz I, ties Porto to Vila Nova de Gaia across the Douro. It was designed by the engineer Théophile Seyrig, a disciple of Eiffel, and opened in 1886 with two overlapping iron decks. The bridge is 395 m long, and until 2017 its arch was considered the largest in wrought iron in the world. Today the upper deck carries Porto's Metro between the cathedral area and Jardim do Morro in Gaia, high above the river with views over the city's houses down to the mouth of the Douro. The lower deck runs at river level between Ribeira and the Gaia port cellars, and it is an easy, scenic stroll in either direction.
Tip: Follow Visit Porto's one-day plan: take the Yellow Line toward Santo Ovídio to Jardim do Morro across the top deck, visit the cellars, then walk back over the lower deck.

Eat custard tarts at Pastéis de Belém
Pastéis de Belém has been baking its custard tarts next to the Jerónimos Monastery since 1837. The story begins after the liberal revolution, when Portugal's convents and monasteries were shut down in 1834 and someone from the monastery began selling sweet pastries in a small shop beside a sugar cane refinery. Their recipe is still a secret, known only to the master confectioners who make the pastries by hand in the bakery's secret room, using traditional methods. In those days Belém felt far from Lisbon and was reached mainly by steamboat. Today trams run out from the center, and the shop makes a natural break between the monastery and Belém Tower.
Tip: The shop opens at 8:00 AM every day, so it makes an easy breakfast stop before the monastery opens at 9:30 AM.

See Belém Tower standing guard on the Tagus
Belém Tower is the icon of a country shaped by the ocean and a UNESCO World Heritage Site. In the 15th and 16th centuries, Portuguese voyages of discovery made Lisbon the world's main trading hub, and King João II planned a pioneering defense to keep enemy ships out of the river. The work was finished in 1514 and included this tower, designed by the architect Francisco de Arruda, with a heavily armed bastion jutting out over the water. King Manuel I had it carved with his emblems, the royal coat of arms, the armillary sphere and the cross of the Order of Christ, as a lasting symbol of his reign. Its tickets are sold at the same kiosk as the monastery's.
Tip: Book online in advance, since tickets often sell out and can't then be bought on the day, and note that the tower is closed on Mondays and may close in rough weather.

Hear fado in an old Lisbon neighborhood
Fado is Lisbon's own song, a blend of music and poetry inscribed by UNESCO on the list of Intangible Cultural Heritage of Humanity in 2011. A solo singer, man or woman, is traditionally accompanied by an acoustic guitar and the Portuguese guitar, a pear-shaped cittern with 12 wire strings found only in Portugal. You can hear it on concert stages, in small fado houses, and in amateur associations across the city's older neighborhoods, where it is often handed down within families. Alfama is a natural place to start, with fado houses and restaurants open into the night. For background, the Museu do Fado tells the history and introduces the people who sing and play it today.
Tip: Visit the Museu do Fado before an evening show to get to know the singers, and note it closes on 1 January, 1 May and 24, 25 and 31 December.

Descend the Initiatic Well at Quinta da Regaleira
Quinta da Regaleira sits at the edge of Sintra's historic center, on the road between the National Palace of Sintra and the Palace of Seteais. Philanthropist António Augusto Carvalho Monteiro bought the estate in 1893 as a summer house, and between 1898 and 1910 the Italian architect and set designer Luigi Manini turned it into a total work of art, now seen as the masterpiece of Neo-Manueline art. Its palace, chapel and gardens are full of symbolism. The best-known feature is the Initiatic Well, which you walk down in one direction only before following underground passages to the Eastern Grotto. Visits are self-guided with a map, and audio guides with 30 listening points are for rent.
Tip: Buy tickets only on the official online ticket office, pick one of the half-hour entry slots, and arrive within an hour of the time printed on your ticket.

Stand under the tiles of São Bento Station
São Bento is a working railway station with one of Porto's finest tile panels. It was built at the start of the 20th century on the site of the former Convent of São Bento de Avé-Maria, with a glass and iron structure by the architect Marques da Silva. The reason to step inside is the entrance hall, lined with about 20,000 blue-and-white tiles painted by Jorge Colaço, showing scenes from Portuguese history and daily life alongside the evolution of transport. Next door on Rua da Madeira, a community tile panel of 3,300 tiles, painted by locals and visitors, answers the question "Who are you, Porto?". It takes only a few minutes to see, and it sits right on the walk from Ribeira to the Avenida dos Aliados.
Tip: It is a busy working station, so keep to the edges of the hall while you look up at the panels, and remember MiraDouro trains to the Douro Valley leave from here.

Ride the MiraDouro train into the Douro Valley
The Douro Valley, where the grapes for port wine grow on terraced hillsides, is the oldest demarcated wine region in the world and a UNESCO World Heritage landscape. The easiest way in without a car is CP's MiraDouro train, which runs daily in both directions from Porto São Bento to Régua, Pinhão and Pocinho. Its restored Schindler carriages from the late 1940s have panoramic windows that open, so you can lean out over the river as you ride. Get off in Peso da Régua for the Douro Museum, or at Pinhão, where the riverside station is decorated with old tile panels about growing vines. The vineyards are green in summer and turn flame-colored in autumn.
Tip: Check CP's timetable before you go; the separate Douro Historical Train between Régua and Tua runs only in summer, so check next season's dates if you want it.

Book a time slot at Livraria Lello
Livraria Lello has been dedicated to books and culture in Porto since 1906, and it calls itself the most beautiful bookstore in the world. Inside, the famous crimson staircase links its two floors, under an illuminated stained-glass window and among neo-Gothic details and carved wooden shelves. Porto's tourism board notes it is said to have inspired the author of Harry Potter. Entry is by a Ticket-Voucher, and its value comes off the price if you buy one of the shop's own Livraria Lello editions. There is also a room of rare books and first editions. Plan on about 45 to 60 minutes, though you can stay as long as you like while it is open.
Tip: Book your time online before you go, since you can't enter without a ticket, and arrive on time: the voucher is valid only up to 60 minutes after your slot.

Watch Lisbon from its hilltop miradouros
Lisbon spreads over hills, and its miradouros, or viewpoints, are where the city stops to look at itself. Miradouro da Senhora do Monte is one of the calmest, with a panorama of the castle, the Graça church, the Baixa rooftops, the ruins of Carmo and the Tagus estuary. Its chapel was founded in 1147, and it is said to be where Afonso Henriques, Portugal's first king, gathered his troops to take Lisbon. On the climb through Alfama, Miradouro de Santa Luzia adds a garden, a pond and tile panels of Praça do Comércio before the earthquake. For sunset, Miradouro de Santa Catarina looks across the estuary and the bridge, beside a statue of Adamastor, the monster Camões placed at the Cape of Good Hope.
Tip: Go to Senhora do Monte for a quiet view at any hour, and to Santa Catarina at sunset, when it fills with music, conversation and people watching the sun go down.

Walk the ramparts of Sintra's Moorish Castle
The Moorish Castle stands alone on one of the peaks of the Sintra hills, a fortress founded in the 10th century, while the Moors held the Iberian Peninsula. Its walls snake across the hilltop, their granite blocks linking boulders and cliffs. Walk the parapet for views over Sintra town and Pena Palace, with the green hills giving way to the blue of the Atlantic in the distance. Inside the walls are the remains of the Church of São Pedro de Canaferrim and a medieval Christian necropolis. Like Pena, it is closed to private cars, so arrive on foot along the walking trails or by public transport from Sintra station. Dogs are welcome too.
Tip: Buy your ticket online or use the machines at the gate, since the staffed ticket office closes from 12 to 1 PM.

Climb the Clérigos Tower above Porto's rooftops
The Clérigos Tower has dominated Porto's skyline since 1763, a baroque landmark by the Italian architect Nicolau Nasoni, who also designed the church at its foot between 1732 and 1749. The tower rises 75 m, and from the top you get a 360-degree view over the city's historic center, a UNESCO World Heritage Site since 1996. Before or after the climb, step into the church to see its unusual elliptical nave with carved, gilded woodwork and a rococo altarpiece in marble of four colors. The museum tells the story of the Brotherhood of the Clérigos, founded in 1707. On Saturdays at 5 PM the church holds a full Mass in English.
Tip: Last entry is 30 minutes before closing, and Porto Card holders get a discount on the tower and museum ticket.

Spend an evening in Bairro Alto
Bairro Alto is the heart of Lisbon's nightlife, set in one of the city's oldest quarters. In the evening its streets fill with people of all ages who come to catch up over a drink and watch the crowd go by, and its many bars and restaurants cover every taste and kind of music. Lisboetas like to say a night out runs downhill: it starts in Bairro Alto, carries on down to Bica with a glass in hand, and ends in Cais do Sodré, where clubs sit beside old sailors' bars. By day the neighborhood is calmer, with alternative shops selling records and art, so come back in daylight to see its streets without the crowds.
Tip: Keep your drink in sight and your belongings close late at night, since the UK government says risks are highest around popular nightlife areas, and call 112 in an emergency.

What are the best things to do in Portugal for a first trip?
Split your time between Lisbon and Porto. In Lisbon, see the Jerónimos Monastery and Belém Tower, climb through Alfama to São Jorge Castle and hear fado at night. Give Sintra a full day for Pena Palace, Quinta da Regaleira and the Moorish Castle; it is a train ride from Rossio. In Porto, walk Ribeira, cross the Dom Luís I Bridge to the port cellars of Vila Nova de Gaia, then ride the MiraDouro train into the Douro Valley.
Sources: Visit Portugal (official); Parques de Sintra (official); CP Comboios de Portugal (official)How many days do you need in Portugal?
For a first trip, about a week covers the two main cities well. Porto's tourism board says you need at least 3 days to really get to know Porto, and Lisbon, with Belém and a day in Sintra, deserves at least as many. The fastest Alfa Pendular trains link Lisbon and Porto in a little under 3 hours, so the move between them takes half a day. Add a day for the Douro Valley, an easy train trip from Porto.
Sources: Visit Porto (Associação de Turismo do Porto e Norte); CP Comboios de Portugal (official); CP Comboios de Portugal (official)What is the best time to visit Portugal for sightseeing?
Spring and autumn suit city sightseeing best: Visit Portugal singles out Lisbon and Porto in the mild climate of autumn or spring. Summers are hot and dry, especially inland, and the UK government warns of higher than normal temperatures and a wildfire risk from April to October. Autumn often brings warm, sunny days, and fine weather in early November is called St. Martin's Summer, after the saint's day on 11 November. Winters are mild compared with the rest of Europe.
Sources: Visit Portugal (official); Visit Portugal (official); GOV.UK Foreign travel adviceDo you need to book Portugal attractions in advance?
For a few big sights, yes. The Jerónimos Monastery and Belém Tower ask you to buy online ahead, since tickets often sell out and can't then be bought on the day. Pena Palace tickets are for a set date and entry time. Quinta da Regaleira sells half-hour entry slots through its official online ticket office only. Livraria Lello in Porto can't be entered without a ticket. São Jorge Castle sells tickets online or at its ticket office.
Sources: Mosteiro dos Jerónimos and Torre de Belém (official); Parques de Sintra (official); Quinta da Regaleira (official); Livraria Lello; Castelo de São JorgeHow do you get around Portugal as a first-time visitor?
Trains link the main places. CP's Alfa Pendular runs between Lisbon Santa Apolónia and Porto Campanhã in a little under 3 hours, with free Wi-Fi and a power socket at every seat. Sintra line trains leave Lisbon from Rossio, Oriente and Entrecampos. In Lisbon, the metro needs a rechargeable navegante or Viva Viagem card, and trams like the No. 28 climb through the old quarters. In Porto, the metro's Yellow Line crosses the top deck of the Dom Luís I Bridge to Gaia.
Sources: CP Comboios de Portugal (official); CP Comboios de Portugal (official); Parques de Sintra (official); Metropolitano de Lisboa (official); Visit Lisboa (Turismo de Lisboa); Visit Porto (Associação de Turismo do Porto e Norte)Is Portugal safe for tourists?
Petty theft is the main thing to watch. The UK government warns of street crime on public transport and at crowded bus and tram stops, where thieves use distraction and often work in teams, so keep your passport, money and phone close. Take extra care late at night around nightlife areas and keep your drink in sight. At the beach, follow the flags: red means don't enter the water, and yellow means paddle at the edge only. The emergency number is 112.
