Tips

Pozo Negro is a glacial lake located at an altitude of 1,760 meters in the Sierra de la Demanda, within the Fresneda area of the Sierra Tirón. It is an isolated and difficult-to-access spot, making it a very attractive spot for hikers seeking unspoiled nature. Its cold, dark waters, protected by Otero Peak, are the source of the Tirón River and are home to unique species such as the endemic palmate newt.

The route to the lake, from the Tres Aguas refuge, takes more than three hours, passing through beech forests and high mountain areas. Therefore, it is advisable to wear good footwear, and bring plenty of food and water.

Glacial lagoon accessible by a steep slope. A delight for the senses.
