Portugal may be Europe's last best undiscovered place. As regional as it is small, Portugal deserves at least a week if not three. We recommend that you build your trip around Lisbon or Porto, and explore from one of those cities. Near Lisbon the Alentejo region feels old world with it's traditional villages, historic wineries and home cooking in portions suited to the days when the meals fed workers in from the fields. Up north Porto grew around the wine trade, being the place where Port wines were aged. Up river from Porto is the Douro River Valley where steep hillsides planted in vines and centuries-old quintas produce both Port and non-fortified wines.
