Arribes is a rocky, end-of-world location on the Spain-Portugal border, where Río Duero becomes the Douro. The name translates to 'high above the Duero'. The land is a combination of high altitude rolling plains and deep, steep canyons lurching down to the Douro's water course, at altitudes between 650-750m. It's hot (hotter than nearby Toro, for example) but also relatively moist. It is intensely remote.
