Lago de Truchillas, Glacial lake in Sierra de la Cabrera, Spain

Lago de Truchillas is a glacial lake nestled in the Sierra de la Cabrera with deep blue water surrounded by slopes covered in heather and juniper vegetation. The water sits below Pico Vizcodillo mountain, enclosed by rocky terrain and alpine landscape.

The lake was formed during glacial times as ice carved out the mountain terrain, creating this distinctive high-altitude formation. Official protection came in 1990 through a regional decree that recognized its geological and ecological importance.

The lake holds deep meaning for residents of Truchas, who have long lived with this natural landmark as part of their daily surroundings. Visitors come to experience how mountain communities relate to their landscape through outdoor traditions and respect for the environment.

The protected area covers 1,066 hectares in the municipality of Truchas, in the lower Eria valley beneath Pico Vizcodillo (2,121 m). Its southern and western boundaries follow the provincial border with Zamora, and the eastern limit follows the watershed of the lake's basin. Access is on foot; the terrain is mountain terrain, so plan for elevation gain.

The protected area covers 1,066 hectares around the lake, and its boundary follows the watershed of the lake's basin rather than a simple shoreline. On the west the limit runs along the dividing line down to the Vizcodillo peak, at 2,121 m, and on the north it passes the spots Los Fontanales and Los Caleyos de Fondivilla.
