A Great Beauty
The Biosphere Reserve of Urdaibai extends itself on both sides of the estuary of the Oka River.
This protected space of great beauty and rich in fauna covers the sea board of the ria of Mundaka, the immense sandy areas and the earth that surrounds it. Gernika, the main city of the reserve is found at the end of the ria. From there begins the adventure of discovering the rural interior of the valley and the sea shore.
On the right sight of the ria, Urdaibai shines in all its splendor. You only have to surround the coast to discover the marshes torn by winding canals –today it is the most important humid area of Basque Country-, the landscape full of crops on its soft hills, the scattered villages, and the Cantabrian oaks next to the empty hills of sand.
