Porto introduces itself through the Ribeira first: those colorful houses stacked one on top of another, laundry hung from the windows, the old rabelo boats moored at the quay. It is the postcard, and the postcard is genuinely lovely. But the real Porto lives in the lanes climbing up behind the waterfront, where life keeps its old rhythm, paying no mind to the cameras.
Crossing the Dom Luís I Bridge on foot, the river below and the city's rooftops spread out before you, is worth the day on its own. On the far side sits Vila Nova de Gaia, and that is where much of the history you came to taste actually rests.
