One of the great things about wandering around in Porto Portugal are all of the winding streets that crisscross the hillside next to the Douro River. You can get lost wandering the skinny streets and back alleyways of Porto. Wandering off the beaten path, you get a candid glimpse into the lives of the people of Portugal, and some fabulous photo opportunities to boot! When you are tired of wandering the alleys, head down to the river side to the port wine cellars to do a port wine tasting (or two, or three!)
