Barragem de Miranda

Down the vertiginous hill below town lies the Barragem de Miranda hydroelectric dam and border – the road runs over the dam wall into Spain and on towards Zamora. It’s one of the largest hydroelectric dams in the country and marks the point at which the Portuguese Rio Douro transforms itself into the Spanish Rio Duero. Boat trips through the gorge are an obvious attraction and they run year-round.
