Porto is smaller, grittier, and in some ways more immediately lovable than Lisbon. The Ribeira district tumbles down to the Douro in layers of peeling façades and laundry-strung balconies, and across the river in Vila Nova de Gaia, the port wine houses have been ageing barrels in cool cellars since the 1600s.
The Ribeira and Dom Luís I Bridge
Walk the lower deck of the Dom Luís I Bridge for the postcard view back at the Ribeira's stacked houses, then cross to Gaia and take the upper deck back, it's higher, more exposed, and gives the better wide shot of both banks at once. Do this near sunset when the light hits the tiled façades directly.
Down in the Ribeira itself, the riverside promenade is lined with tascas serving francesinha, Porto's improbable, essential sandwich of meats, cheese, and beer-tomato sauce. Eat it early; it's not a dish that sits well after 3pm.
Port Wine Cellars in Gaia
Every major port house (Graham's, Taylor's, Ferreira, Sandeman) runs cellar tours in Gaia ending in a tasting, and they're worth doing at least once for the education alone: tawny versus vintage, how the barrels breathe, why the Douro Valley's schist soil matters. Graham's has the best terrace view back across the river.
Livraria Lello, the neo-Gothic bookshop said to have inspired Harry Potter's staircases, is worth the ticket price if you go right at opening, by mid-morning the queue wraps the block.

Torel Palace Porto
A hillside boutique hotel above the Ribeira with a small infinity pool looking down over the rooftops to the Douro, one of the few hotels in Porto where the view alone justifies the stay.
