Douro Valley

This valley is one of Portugal's scenic highlights, with some 200km (125mi) of bold, expansive panoramas stretching from the city of Porto all the way to the Spanish border. In the upper reaches, port-wine vineyards wrap around every crew-cut hillside, interrupted only by the occasional blindingly white manor house. The roads which wriggle along the banks of the Rio Douro can be crowded with day-trippers from Porto, but the river has been tamed by five dams and is now navigable along its entire length, making boat cruises an attractive way to soak up the atmosphere in peace.
