Porto things to do or day trips? Is a week too long?

Three days dedicated to Porto followed by four days Douro River cruise.

Thanks! Any good multi day cruises companies you can recommend?

I've spent 6 days in Porto and could easily spend another week. I'm not a sweet wine drinker, but did do the Sandeman cellar tour with the vintage ports. Had more fun with the group than anything. A couple of us still keep in touch.

I did a one day trip in a van with a party of 8 up into the Douro. Again, I live in wine country so what interests me isn't usually what tours show. I did enjoy seeing the layouts of a couple of the smaller vineyards we visited. It's a very pretty valley.

While the area around the mouth of the river is tourist central, I enjoied just walking through the local neighborhoods. The Bolhau market was really nice, good food, and near the center of town. Easy to reach by bus.

I also liked the beach, north of the city proper, at Matosinhos. There's a park, an old fort, surfers, warm water, boats to watch, and excellent sundowns on the sand. Good food and drink on the boardwalk also. You can spend a lot of money , but they also have a couple markets (Lidl, etc) where you can grab some supplies and sit on the beach.

The churches are spectacular, but I spent more time just looking at the tilework on ordinary buildings. I also just crawled around a number of local craft venues, but didn't do any museums. Those are for the next trip...

Hi!

Gastronomical tour: https://tasteporto.com/pt/

They are very good.

Wine cellar to visit: they are all nice, but Graham's, Taylors and Croft are usually the preference of many people to make a visit and tasting. But if you just want to relax and drink some wine, Porto Cruz has a very nice rooftop. Concerning the building, my favourite is Sandeman.

Day trips:

• Matosinhos is as described above. You can take the metro there, the bus, or uber/taxi/bolt (unexpensive). Would just like to add that you should visit the market, and also that best restaurants are at Rua Heróis de França and around that street.
• Vila do Conde - a small town with nice gardens, beaches, architecture, etc. You can go there taking the metro.
• Braga, Guimarães (both North from Porto) and Aveiro (South): just take the train at one of the train stations, São Bento or Campanhã. Each of them is more or less one hour ride. Braga has an atraction, a church on a hill with a beautiful staircase, just outside the city, named Bom Jesus. Guimarães is very nice and historical, as it is where Portugal was born. Aveiro is an interesting city with some water channels, and nearby (12 kms more or less) is Costa Nova, by the ocean, with very typical stripes houses.

Museums in Porto: imo you should not miss MMIPO at Rua das Flores. The visit includes both the museum and the church. If you like sports, take the metro to "Estádio do Dragão" and visit the museum of Futebol Clube do Porto.

On Saturdays, there are 2 open air markets where everything you can imagine is being sold: clothes, fruits, furniture, etc. During morning the sellers are at Senhora da Hora, you can go by metro (all lines), during the afternoon they are at Custóias - metro towards ISMAI, leave it at "Candido Reis" stop and follow the crowd.

Just some ideas for things to do, hope some of them might be usefull.
