The Rio Douro (river of gold): a narrow, winding gorge for the major part of its long route from the Spanish border, with port wine lodges dotted about the hillsides with a series of tiny villages. The valleys and tributaries form some of the loveliest and most spectacular landscapes in the whole of Portugal.
If you take a boat up river, worth taking the train back down an admire the region’s increasing dramatic scenery unfolding before you.
For a family run stay, Quinta de la Rosa is ideally located outside the main centre for ports, Pinhao. https://quintadelarosa.com/ And maybe help with the treading of the grapes !
