4 days is short. You may want to spend 2 nights in Porto and then find a vineyard that is not too far up the Duro river so you can enjoy 2 days walking around between the grapes.

Hi. Sorry for the delay in answering but I have been away from this site for a long time. You can get one way. My wife and I did the trip from Porto and got the train back the same day. We used Cruzeiros Douro. They do day trips both ways and return by bus. They give a small discount if you arrange your own return. You do need to check their schedule as they go one way one day and then the other the following. They go through the deepest locks on the river which is what we were after. One thing to look for is there is an old fashioned steam train which travels back to Poto but it runs at limited time and dates. The rest of the time it’s just a normal commuter type train. The views are great as it runs next to the Douro but does break away the closer it gets to Porto. The end of the line is Porto Sao Bento railway station which deserves a visit to see its fantastic tiles. Have a great trip

going in next sept. 3 guys want to hike back to porto any ideas ???

Hi there, you can get a cruise from there, sorry it's taken so long to answer :))

You are in for a great trip. I have never been to Porto in Spring, only Algarve. Porto is wonderful. After taking the Hop on Hop off bus tour to get to know all the main "attractions" and discovering the nice things of Porto I would suggest at least one day trip to Guimares. Taking the train there is not expensive and quite easy to do. You will see the Douro Valley by boat - not sure how many times you stop and get off to visit a wineries - if it is not many you might want to take a day trip from Porto to Pinhao. That can be by train or an organized trip with a mini van - 8 to 10 persons. Although I am not a vegetarian I did eat at a great vegetarian restaurant, only I for get the name now. Most restaurants do have vegetarian choices. I Uber often but in Portugal it was not nesc. as Taxis are very affordable. Our next trip we will do day trips from Porto to Braga and Coimbra, both are easily reached by train. Have fun.

Oporto e Duoro can accommodate a baby, they give an excellent tour.

I agree with the other suggestions. The Duoro valley is definitely worth a full day. We took the train out of Porto to Pinhao. Had lunch in Pinhao then took a boat tour. Did wine tasting at two vineyards and then took the last train back to Porto. It was a great day.

Hello, there. Hope you like the visit at least as much as we did. There are several options regarding boat tours. We took the shortest one, only a few hours tour, and visited the rest by car. However, we did so because there were no vacancies to the longer one day tours. There are some options of several day cruises that go all the way to Spain too, but that starts to become a little pricey. My girlfriend has much more details. If you want, I can ask her.

Hi, you will find wineries all over the place and there are clear signs. Most of them offer tasting, a few only by appointment. Most of them are good.
