Stroll around the Jardins do Palácio de Cristal
Portugal’s got plenty of clout when it comes to botanical gardens, and Porto’s no exception. The Jardins do Palácio de Cristal are a sliver of green in the urban city centre, where sculpted hedgerows, shady lawns and pavilions are intersected by pathways. Plus, the Douro River is down below you, so there are plenty of panoramic viewpoints to make the most of.
