Sanabria Lake, Glacial lake in Zamora Province, Spain.
Sanabria Lake is a glacial lake in Zamora Province formed during the ice age with considerable depth in certain areas. Mountains and forested slopes surround the water, creating a natural basin in the landscape.
The lake formed during the ice age when glaciers carved out the valley and left behind water-filled depression. The government established protection for this landscape in the late 1970s to preserve the area.
The restored monastery of San Martín de Castañeda nearby displays exhibits about regional life and the glacial landscape. You can see how monks once lived and worked in this remote mountain setting.
The lake sits along road A-52 between Madrid and Vigo with parking areas and visitor access points available. Summer months offer the best conditions for swimming and walking the shoreline.
Water in the deeper zones stays at near-freezing temperatures year-round, creating distinct conditions for specialized fish species. Few visitors realize how dramatically the lake changes between surface and bottom layers.
