몬테루비오 데 라 디멘다‬에서 가장 멋진 ‪6‬개의 천연기념물

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.

Nice trail area

There is always the solution to difficult points: doing them by road.

With the mountain route you can go up from Fresneda, reach the Pozo Negro (durillo), and from there to the Cruz de la Demanda, returning to Fresneda by road and passing through the top of La Pradilla.

The railway crossed this port through a tunnel. When making the greenway, the original route was not recovered, so the arrival and departure of the port are two very steep slopes. Most panniers make them by pushing the bike.
