I was hoping you would not do the same mistake with the route, I just ended up on the motorway and I did not see much from the Douro valley.
If you want the best route, just follow the steps in this video.
If you do not like driving, I would advise you to use the Cruises, then you can go up the river, and enjoy the wine and the view without worrying about driving on curvy roads. [www.roteirododouro.com/en/dou...](www.roteirododouro.com/en/dou...)
I am not affiliated with this company, I just did a quick search and found these prices from 60 to 200 euros for all tastes.
There are more expensive cruises with a lot of activities. Remember normally you must pre-book and these only work from May to December
Have a nice trip and enjoy Porto a fantastic place
