Urdaibai, paradigm of the balance between people and nature. An extraordinarily beautiful space where nature, heritage and culture, its villages and its people coexist in harmony, a landscape rich in contrasts with an extraordinary naturalistic value. 22,000 hectares integrated in a mosaic of cliffs, mountains, beaches, rivers and subway waters, offering a spectacular landscape full of animal and human life. Urdaibai, now, almost forty years after its declaration as a Biosphere Reserve, is shown as a destination to know and enjoy layer by layer: its culture, its identity, its nature, its gastronomy, its wines and its high quality of life.
