Sanabria Lake Natural Park is situated in the northern region of Spain in the northwestern region of the Zamora province. The park spans 22,365 ha (55,265 acres) across northern Spain.

The park encompasses the land around Sanabria Lake and extends out to the west. Here lie the mountains of the park including Pena Trevinca. The lake is known for being the largest lake in Spain that is of glacial origin, covering 368 hectares (899 acres). The maximum depth of the lake reaches 53 meters (173 ft).

The rest of the park consists of the mountains surrounding the lake which includes canyons and smaller lakes. The main flow of the lake is fed by the river Tera. The lake itself is a large widening with the river.

The park is part of the Sierra de la Culebra mountain range which extends from northeastern Portugal across northwestern Spain. The range is characterized by their rolling formation and wooded slopes.

Additionally, Sanabria Lake Natural Park is surrounded by other popular outdoor recreation areas.

The lake, along with the surrounding peaks of the park create a vast glacial landscape. The cirques, valleys, and moraines showcase the historic formation of the region. The summit of many of the peaks in the region, and the Sierra de la Culebra mountain range, consists primarily of quartzite.

The Quaternary glaciers formed an ice sheet that covered the entire region. As the ice receded, a large U formation left behind the Tera valley. As the ice melted and carved out the Sierra de la Culebra, numerous glacial lakes and rivers were left behind. Now the smooth slopes left behind surround the largest glacier fed lake in the country.

Major peaks within the park include Pena Trevinca, Pena Negra, and Alto Ladeira de Medias.


The fertile soil of the region allows for flora to thrive. Despite the smaller size of the park, it is still home to over 1,500 species of. Oak trees dominate much of the landscape, from the lake shores up to the rolling hills.

Other regions in the park are populated by chestnut, ash, willow, and holly trees. At the highest elevations in the park are scrubland and heath, typical of the surrounding region.

Perhaps the most notable species of the park is the wolf. Iberian wolves are found in the park in the surrounding region along with roe deer, wild boar, and otter. The sky of the park is home to eagle, peregrine falcon, buzzard, and various other birds of prey. Sanabria Lake is home to numerous species of trout.
