Most of the rivers in Spain are fed by rain, which leads to sharp seasonal fluctuations in water levels. The exception is the rivers located in the north and northwest of the country.
River guadiana
The river bed is a natural border dividing the territory of Portugal and Spain. The total length of the river channel is 778 kilometers. The source of Guadiana is the La Mancha plateau and further to the Gulf of Cadiz (river mouth).
The river suffers from a huge amount of river sediment and, moreover, is not too deep. But all this does not in the least frighten tourists who are happy to go on river cruises in Guadiana. After all, such river walks are surprisingly interesting. On the banks of the river, you can see many picturesque ruins, beautifully preserved ancient fortresses. The bells of the temples, which are also quite numerous on the shores of the Guadiana, beat off the clock. And then a beautiful bell chime rushes over the river.
During stops, you can buy beautiful souvenirs made from stones found in the waters of the river.
Duero River
One of the largest rivers flowing through the territory of the Iberian Peninsula. The source of Duero is in the Iberian mountains and then it carries its waters to the shores of the Atlantic, flowing into the ocean already on the territory of Portugal.
In Spain, Duero leads its way through the wine-growing region of the country - Ribera del Duero. Then she "looks" into the city of Zamora and goes to the most beautiful canyon in all of Europe, which has assumed the role of a natural border between two states - Spain and Portugal.
Ebro river
The Ebro is the second longest river in the Iberian Peninsula, behind the Tagus. The source of the river is located near the man-made Lake Embails del Ebro. The upper course of the river is quite turbulent and it makes its way through the rocky gorges of the province of Burgos. Descending lower, the river becomes calmer, which is facilitated by the expansion of its valley.
Tahoe River
The Tahoe is the largest river in the Iberian Peninsula. The source of the river is in Spain, but the Tajo ends its run near the capital of Portugal, the city of Lisbon, flowing into the waters of the Atlantic. The total length of the river is 1038 kilometers. The approximately 47 kilometers of the Tagus River is the natural border between Spain and Portugal.
While still in Spain, Tajo passes through the territory of several provinces of the country: Aragon; Castile - La Mancha; Madrid; Extremadura. Then Tajo passes to the territory of Portugal.
River Minho
The total length of the Minho is only 340 kilometers, and, like many other rivers in the country, it belongs to two states at once - Spain and Portugal. The source of the river is the Cantabrian mountains. In its upper course, the Mignot is a relatively narrow river. And only after the Sil (the main tributary of the river) flows into its waters, the Minho Valley expands significantly.
