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.
