Valdeaniezo valley (or narrow valley) is one of the valleys in the bottom west of the Sierra de Peña Sagra. This route starts from the village of Aniezo, next to the Parque del Agua, which has some exhibits related to the moving strength of water from the 19th century industrial archeology. A mill and a fuller, which would be used to press and compact wool used to make blankets or shoes, are good examples of the utilisation of natural resources.The old path which used to join Aniezo and Somaniezo, along the river, is the first part of the route. Black alder (Alnus glutinosa), hazel (Corylus avellana), black poplar (Populus nigra), ash (Fraxinus excelsior) and willow (Salix sp.) make up the variety of vegetation which runs along the river bank at this point. Near Somaniezo, we take the path to the highest point of the walk, Collada de Perejita. The path goes through little creeks, switching sides several times, which allows us to see how vegetation changes depending on the direction, going through oak forests (Quercus Pyrenaica) exposed to the West and the beech forests (Fagus Sylvatica) in more humid places, on North-facing sides.The Collada de Perejita is located in the mountain range which borders Valdeaniezo to the South, where a wide field allows us to enjoy a panoramic view of Liébana: the Picos de Europa to the North the highest peaks of the Cantabrian Range, Peña Prieta and Curavacas to the South and West, and the Sierra de Peña Sagra to the East. Here again we can see the environmental changes which are caused by the mountain profile depending on the direction, and the atlantic influence on the Northern sector which we ascended. It develops the typical Mediterranean ecosystem on its South face, with holm oak as the predominant species (Quercus ilex sub. rotundifolia). The route finishes with an easy walk on the high area of the range, from Perejita to Somasierra, to then descend through the Northern face back to Aniezo.
