A group of lakes formed in glacial cirques surrounded by peaks approximately 2,000 meters high. Between 1969 and 1972, a project was developed to transform the glacial complex for tourism and intensive fishing. Some of the consequences of this project included the alteration of moraines, land clearing, the creation of dams, and the construction of roads.

In the Laguna Negra de Vinuesa there are two Portillas that allow climbing to both ends, right and left, of the cliff that surrounds it. The Portilla on the Right side allows the climb towards Pico del Zorraquín. The Portilla de la Izquierda, shorter and easier to climb, puts you on the path to climb the Pico de Urbión, either through the Laguna Larga or the Laguna Helada. On the way up to this Portilla you will find the Arroyo de La Laguna with its beautiful waterfall, where it is essential to stop to admire and photograph it.

To climb from Laguna Negra to Pico de Urbion, please wear suitable footwear for trail or mountain... do not go with beach flip-flops as I have already seen more than one and more than two sprains due to this imprudence.
