1. Ribeira Square
If you’re in Porto you absolutely, positively must visit Ribeira Square. This old city district located by the Douro is a Unesco World Heritage Site. Yes, it’s swarming with tourists, but don’t let that put you off. Cross the river in a rabelo boat; go wobbly looking at the Luíz I, D. Maria II and Arrábida bridges (great backgrounds for dramatic photos); visit the Bacalhoeiros Wall, the Casa do Infante museum, the Rua da Reboleira, Cubo square, São Nicolau Church and the ‘Alminhas da Ponte’, a sculpture by artist Teixeira da Lopes. Eat at the Adega de S. Nicolau (they sometimes have fado nights), drink at the Pestana Vintage Hotel’s amazing RIB bar, and then head up to the heights on the Guindais Funicular Railway. Phew!
