This is the last set of photos and it shows the olive plantations that are also an important part of the landscape, some wine cellars, and the Pinhão river, a Douro tributary. I hope you enjoyed this series. The Douro Valley is a magical place with a long tradition of wine and olive oil production. Its sustainability is currently threatened by an increase in intensive farming and tourism. In a way, it’s being a victim of its own beauty and of the quality of its products.
