Vindima – Douro Harvest Festival

September and October bring the vindima (wine harvest) to the UNESCO-listed Douro Valley — one of the world's great annual spectacles. Villages like Pinhão, São João da Pesqueira and Lamego host harvest festivals where visitors can join the grape-treading in granite lagares, ride the Douro line train through terraced vineyards ablaze with autumn colour, taste wine direct from the barrel and stay in historic quintas. A deeply immersive agricultural and cultural celebration.
