During the Upper Pleistocene age, over 100,000 years ago, an impressive glacier with ice tongues of more than 20 kilometres in length gave rise to what is currently known as the Lago de Sanabria.Today, its 318 hectares of surface area and depth reaching 51 metres make it the largest lake in the Iberian peninsula.

The abundant forests surrounding the Lago de Sanabria are formed by Pyrenean oaks. There are also interesting clumps of holly and yew trees while birch trees and alders are plentiful in the banks of the rivers that descend from the summits or link the different lakes contained within the natural park.

El Cañón del Tera

Very near the riverbank of the Lago de Sanabria, in Ribadelago Viejo, is the starting point of the walk through the narrow and spectacular Cañón del Tera. On leaving Ribadelago Viejo, and always parallel to the river's course, is the gorge. After leaving the path to San Martín de Castañeda to the right and crossing the Tera through an improvised walkway, the trail continues through an area full of large stones, brought there by the water current.
