Stand at the edge of Largo do Trabalho as the light drops behind the Guaíba and the old power station turns into a silhouette. That half-hour at the waterfront, with the wind coming off the water and a crowd gathered along the railings, is the moment most visitors remember from Porto Alegre.
The city suits travellers who are happy to build a day around a lake, a park and a museum rather than a checklist of monuments. It rewards slow mornings, long walks and an interest in gaúcho culture, art and barbecue.
This guide covers the sights and experiences worth your time, followed by a plan for a single day and answers to the questions visitors ask most often.
Top things to do in Porto Alegre
1. Watch the sunset over Lake Guaíba
The sunset over Lake Guaíba is the city's signature experience. The best places to watch it are the waterfront of the Historic Center, near Usina do Gasômetro, and Ipanema.
The event itself lasts only about five minutes, so arrive early and stay put. In winter, around July, bring extra clothing, as the wind off the water can be very strong.
2. Usina do Gasômetro
This old power plant, built in 1928, was refurbished and now hosts movie theatres and art exhibitions. It sits at Largo do Trabalho, about 1.7 km from Mercado Trensurb Station.
Come in the late afternoon so you can see the exhibitions and then join the crowd in front of the building for the sunset over Lake Guaíba. It pairs naturally with the Minor Basilica of Our Lady of Sorrows, which is roughly 600 m away.
3. Linha Turismo
Linha Turismo is a tourist bus line that runs through 11 neighbourhoods and shows the main attractions of the city, including parks, trees, statues, hospitals and churches, with audio guides in three languages. The trip covers 28 km and lasts about 1 hour 20 minutes, returning to the same departure address.
It departs from Travessa do Carmo Street 84 and runs Tuesday to Sunday, holidays included. Departure times are 09:00, 10:30, 13:30, 15:00 and 16:30 in winter, or 10:30, 13:30, 15:00, 16:30 and 18:00 in summer. Tickets cost R$30 for a normal fare and R$15 for students; foreigners need an International Student Identity Card for the student rate. It is a sensible first morning if you want an overview before walking.
4. Parque Farroupilha
Known to locals as Redenção, this park contains the Araujo Viana Auditorium, which has hosted political acts and music concerts.
On Sundays an antique fair takes place in a side street and is known locally as Brique da Redenção. Plan your visit for a Sunday if the fair appeals, and otherwise come for a straightforward walk through the grounds.
5. Metropolitan Cathedral of Porto Alegre
Built between 1921 and 1972, this Baroque-style cathedral is constructed from granite stones and has two bell towers and a 65-metre-high dome in its nave. Mosaic murals depict biblical scenes. It stands on Rua Duque de Caxias, about 1 km from Mercado Trensurb Station, and entry is free.
Opening hours vary through the week, with shorter windows on Monday and Saturday and longer ones Tuesday to Friday and Sunday. Check the times before you set out, since the gaps in the middle of the day are easy to miss.
6. MARGS (Rio Grande do Sul Arts Museum)
MARGS is the local museum of art, on Praça da Alfândega downtown. It holds a permanent collection alongside an area that frequently receives new exhibitions, and there is a bistro and a store selling art books and souvenirs. Entry is free.
It opens Tuesday to Sunday, 10:00 to 19:00. Combine it with the surrounding Historic District, and in November with the Feira do Livro de Porto Alegre, which is held at the same square.
7. Iberê Camargo Foundation
This contemporary art museum occupies a building by the Portuguese architect Alvaro Siza, on Av. Padre Cacique. Entry is free.
It is open Tuesday to Sunday, 12:00 to 19:00, and until 21:00 on Thursdays. Bus line 176 serves it.
8. Minor Basilica of Our Lady of Sorrows
The oldest church in the city, built in 1807 and finished in 1904, it has an eclectic style with an interior decorated in gilded woodcarving and an altar holding numerous works of baroque sacred art. It received the status of a minor basilica in 2022. Entry is free.
It stands on Rua dos Andradas, about 600 m from Usina do Gasômetro and 1.3 km from Mercado Trensurb Station, and opens Tuesday to Sunday in two windows, 09:00 to 12:00 and 13:30 to 18:30. It fits neatly into a waterfront afternoon.
9. Parque Moinhos de Vento
Known by locals as Parcão, this is a pleasant park with a neat lake and jogging runways.
It works well as a low-key stop between the museums and the eastern part of the city, and as a place to sit rather than to tick off.
10. Parque Marinha do Brasil
Known simply as Marinha, this is a linear park with a skateboarding rink, several sports and public fitness amenities, and several modern art sculptures by Mercosur artists.
It is good for a bit of nature during the day and is popular on weekend late afternoons.
11. Casa de Cultura Mario Quintana
This cultural centre occupies a building on Rua dos Andradas and is open Tuesday to Sunday, 09:00 to 17:00. Tickets cost R$40, or R$20 for children under 12, seniors, university students and professors.
It sits on the same street as the Minor Basilica of Our Lady of Sorrows, so the two can be visited in one walk through the centre.
12. Museu de Ciências e Tecnologia da PUCRS
The Museum of Science and Technology of the Pontifical Catholic University of Rio Grande do Sul is on Av. Ipiranga, in Building #40, reached by bus lines 476, 343 or 353. It opens Tuesday to Sunday, 09:00 to 17:00.
Tickets cost R$40, or R$20 for children under 12, seniors, university students and professors. It is a good choice for a rainy day or for anyone travelling with children.
13. Sanctuary of Mother of God
This church sits at the top of a hill at 283 metres of altitude, with views over Porto Alegre and nearby cities. It was built in 1992 with modern architecture and engineering designed to withstand the strong winds of the location, and it is free to enter.
It is open Thursday to Monday, 09:00 to 17:00, and is reachable from Avenida Professor Oscar Pereira or by bus line 253. Getting there is somewhat difficult and a cab from downtown would be pricey, so it is worth trying if you rent a car.
14. Climb aboard the Cisne Branco boat
The Cisne Branco offers a boat trip on which you can enjoy the sunset over Lake Guaíba. The trip lasts an hour and a half, leaves at 17:30 from Cais do Porto and sails to the South Zone, accompanied by live Brazilian music.
This is the alternative to watching the sunset from the shore, and it gives you the same light from the water.
15. Watch a soccer game
Porto Alegre has two major local teams, Grêmio and Internacional, known together as Gre-Nal, with a strong rivalry. Grêmio plays at Arena do Grêmio in the North Zone, and Internacional plays at Beira-Rio Stadium on the banks of Lake Guaíba. A smaller club, São José, plays at Passo d'Areia Stadium, also in the North Zone.
If a match falls during your stay, it is one of the clearest ways to see how the city divides its loyalties.
If you only have one day
Morning. Start with Linha Turismo from Travessa do Carmo Street 84 for an overview of the city, then walk to the Metropolitan Cathedral of Porto Alegre on Rua Duque de Caxias while you are still in the centre.
Afternoon. Spend the early afternoon at MARGS on Praça da Alfândega, then walk down Rua dos Andradas to the Minor Basilica of Our Lady of Sorrows and Casa de Cultura Mario Quintana. Continue to Usina do Gasômetro at Largo do Trabalho.
Evening. Stay at the waterfront in front of Usina do Gasômetro for the sunset over Lake Guaíba, which lasts only about five minutes. If you would rather see it from the water, take the Cisne Branco boat, which leaves at 17:30 from Cais do Porto and returns after an hour and a half.
