The region of Liébana is a perfectly defined highland territory, including impressive mountain ranges in some areas. It is irrigated by the river Deva and its two main tributaries, the Quiviesa and the Buyón.It is a closed territory which can only be accessed, from the north, through the Hermida gorge. This is, along a scenic road which follows the river Deva and runs parallel to it, boxed by rugged and almost vertical limestone walls, some of them more than 600 m high.This is a region of a surprising climatic variety, where a properly Mediterranean micro-climate contrasts with the rigours of the alpine meteorology in the highest areas.A natural reserve where some autochthonous tree species still remain like: evergreen and cork oaks, Pyrenean oaks and beech trees, which form intricate and beautiful woods in which a few protected species survive, like the brown bear, the road deer or the cappercaille.
