If you are interested in seeing the best view of Porto, visit the Miradouro da Serra do Pilar at Vila Nova da Gaia. In either direction you look down the Rio Douro, you can see the most breathtaking views this beautiful European city has to offer. It is high on the hill situated in front of the Mosteiro da Serra do Pilar. You can see at least 3 of the different bridges from the lookout and it is a very humbling experience. For a true taste of the depth of the architecture that is built into the hills of this old Portuguese city, definitely go for a visit to enjoy this view.
