Preserved in an exceptional microclimate and integrated into the Sierra Norte de Guadalajara Natural Park we find the last beech forest in southern Europe. The Lillas and Zarzas rivers, which are born in the La Buitrera glacier, feed it. The forest grows in two valleys flanked by high and sharp rocky ridges, which has allowed its conservation over time given the difficult access.
We will find ourselves in a fairytale atmosphere due to the colors of this beech forest, which is a true tourist attraction. In addition, oak groves, wild pines, yews, holly and birch grow. In its soil the appreciated Boletus Edulis grows in autumn, and its skies are crossed by the golden eagle and roe deer, foxes and wild boars walk through its lands.
In 2017, along with other beech forests in Spain and Europe, it was declared a World Heritage Site by Unesco as an extension of the primary beech forests of the Carpathians and other regions of Europe.
