Will be in Porto from Friday March 6th until the 9th. One day I would like to take a scenic train ride, eat lunch in Pinhao, and try a few wineries. I would prefer not to do a tour, but I fear it will be difficult to try wineries without a car(which I am not wanting to rent). I would have no problem taking the 715 am train, but could do later as well. Any suggestions? Mostly interested in beautiful scenery, followed by good food and wine. Thanks in advance.
