The last part of the river Tormes and the river Duero, near the border with Portugal have created a unique situation in the province of Salamanca where spectacular reservoirs alternate with formidable canyons. It is the only possibility that nature has to solve the problem of the notable difference of altitude that separates the lands of the plateau from those of the Spanish-Portuguese border at the jetty de Vega Terrón, in La Fregeneda. Mediterranean climate The climatic conditions are benign and there is a microclimate fully characteristic of the Mediterranean: olive trees, prickly pears, orange trees, etc. The route that we propose goes through all those riverside towns that bring us closer to the shores of the river so we can enjoy the impressive views of the deep canyons of the river Duero and of the tributaries that pour into its waters. Dams and lookouts Ledesma, from its position overlooking the Tormes, is a suitable beginning for a route that goes toward the resevoir of Almendra, the first of a series of spectacular hydroelectric structures that "tame" the flowing river currents. From there you can head toward Villarino del los Aires and visit the lookout posts and balconies of the Duero in Aldeadávila de la Ribera, where you can have an attractive boat ride along the base of the canyon. The following landmarks of your trip are: Mieza, Vilvestre, Saucelle and Hinojosa de Duero, then a descent to the Vega Terrón river port, in the municipality of La Fregeneda, where Salamanca communicates with Oporto and the Atlantic Ocean. Pozo de los Humos and Vitigudino Along the road you will encounter waterfalls like Pozo de los Humos, between Pereña and Masueco, or the cachón de Camaces (next to Hinojosa). You may choose to visit the pre-Roman town of Yecla de Yeltes (included in the Route of Border Fortifications) or travel to medieval areas like San Felices de los Gallegos and the fortress of Sobradillo. Your steps will have taken you to the villages of Lumbrales and Vitigudino. Don't leave the second one without taking a walk through its arched main square, seeing the beauty of its parochial church and enjoying the atmosphere of this urban centre, which is the regional head of the northwest of Salamanca.
