Practical tips for Portugal
- Portugal uses the Euro (€); while contactless card payments are common, always keep cash handy for small cafes, kiosks, and traditional tascas.
- Invest in reloadable transit cards like Lisbon's Viva Viagem or Porto's Andante to easily navigate vintage trams, funiculars, metro, and local trains.
- Pack comfortable shoes with good grip, as Portugal's iconic calçada portuguesa (calcada cobblestones) can be remarkably slippery, especially on steep hills.
Fun fact about Portugal
Portugal is home to the world's oldest operating bookstore, Livraria Bertrand in Lisbon's Chiado neighborhood, which opened its doors in 1732.
