Al abrigo de la Sierra Urbasa-Andía
The Iranztu region contain a rich variety of landscapes. To the north of the Valley is the Urbasa-Andía Mountain Range. A climatic boarder forms which slows and downloads moisture from the Cantabrian Sea. The mountain ranges are two large plateaus with edges raised on the northern and southern slopes.
The karst soil means that, despite the heavy rain and snow, there are hardly any surface rivers as the water seeps into cracks and potholes forming an underground network. These soil characteristics, as well as the relief and weather, determine the three types of existing vegetation in Urbasa and Andía: the forests, clearings and vegetation on the crags.
Deciduous forests occupy most of the Urbasa Mountain Range and are rare in Andía. Beech trees predominate, accompanied by maples, linden, ash and holy.
Amongst the vegetable richness of the park, are included a beautiful specimen of yew, “Yew Otsaportillo”, protected as a natural monument.
