These reaches of the Douro have a [[mesoclimate]]{{specify|date=March 2011}} allowing for cultivation of [[olive]]s, [[almond]]s, and especially [[grape]]s, which are important for making [[Port wine|port]]. The region around Pinhão and [[São João da Pesqueira]] is considered to be the centre of port, with its ''quintas'' (or farms/estates) that extend along the steep slopes of the river valleys. In the 21st century, many of these are owned by multinational, reputed wine companies.

Recently, a prosperous [[tourism|tourist]] industry has developed based on river excursions from Porto to points along the Upper Douro valley.

The [[Douro railway line]] ({{lang|pt|Linha do Douro}}) was completed in 1887; it connects Porto, Rio Tinto, Ermesinde, Valongo, Paredes, Penafiel, Livração, Marco de Canaveses, Régua, Tua and Pocinho.

Pocinho is near the very small city of Foz Côa, which is close to [[Côa Valley Paleolithic Art]] site. This is considered important to the [[archaeological]] pre-historic patrimony, and it has been designated as a [[UNESCO World Heritage Site]].

===Dams===
Fifteen dams have been built on the Douro to regulate the water flow, generate [[hydroelectric power]], and allow [[navigability|navigation]] through [[canal lock|locks]]. Beginning at the headwaters, the first five dams are in Spain: [[Cuerda del Pozo Dam|Cuerda del Pozo]], [[Los Rábanos Dam|Los Rábanos]], [[San José Dam|San José]], [[Villalcampo Dam|Villalcampo]] and [[Castro Dam]]s. The next five downstream are along the Portuguese-Spanish border; the first three are owned and operated by Portugal: ([[Miranda Dam|Miranda]], [[Picote Dam|Picote]] and [[Bemposta Dam]]s), while the next two belong to Spain: ([[Aldeadávila Dam|Aldeadávila]] and [[Saucelle Dam]]s).

The Douro's last five dams are in Portugal, and allow for navigation: [[Pocinho Dam|Pocinho]], [[Valeira Dam|Valeira]], [[Régua Dam|Régua]], [[Carrapatelo Dam|Carrapatelo]], and [[Crestuma–Lever Dam|Crestuma–Lever]] dams. Vessels with a maximum length of {{convert|83|m|ft}} and width of {{convert|11.4|m|ft}} can pass through the five [[canal lock|locks]]. The highest lock, at Carrapatelo Dam, has a maximum lift of {{convert|35|m|ft}}. The waters of Pocinho lake reach {{convert|125|m|ft}} above sea level. Unannounced releases of water from upstream Spanish dams occasionally causes navigation issues in these locks.
