The Forest of Oma is one of the best-known works of the Basque artist Agustín Ibarrola and is an expression of the artistic movement known as Art and Nature, which emerged in the late sixties of the 20th century and whose purpose is to convey artistic work to the natural environment, using the landscape as a framework, support and raw material for the artist.
The work, located in the town of Kortezubi (Bizkaia), is made up of several sets of geometric motifs and figures painted on the trunk of radiata pine trees. The use of natural living supports, the play of two-three-dimensionality and the experience of placing the visitor at the center of the work of art through his discovery, as well as the diversity of responses it proposes, make this work a reference of the Art and Nature movement and of Basque Art in particular.

Navárniz Village

Highlight • Settlement

Navárniz is at the foot of Mount Iluntzar. It stands at around 360 meters above sea level, making it high enough to have great views of the valley and mountains. It is a beautiful little town that is a good place to start an excursion.

Ozollo Errota Tide Mill

Highlight • Monument

The municipality of Gautegiz-Arteaga preserves the only tidal flour mill that once existed on the Urdaibai estuary: the Ozollo Errota tidal mill. Furthermore, the Arteaga mill is the best preserved and the only one that retains most of its facilities. The mill was built around 1683, in the marshland of Laida Beach, in the Kanala area. An area of the marsh was used for its construction, enclosing it with walls, and it was fed by the dam in the rear reservoir. In addition to the milling house, where the drive wheels were installed, the mill has a building at the lowest point of the reservoir. This is a house located on the edge of the estuary, above the same water inlet and outlet. Therefore, the Ozollo Errota tidal mill is the most notable heritage structure in Urdaibai. The mill ceased to operate in the early decades of the 20th century and has been privately owned for several years.

Arteaga Castle

Highlight • Castle

The castle of Arteaga, also known as the castle of Empress Eugenia de Montijo, was built in the 19th century in neo-medieval style on the foundations of an 8th century castle. Its location stands out, in a large flat meadow surrounded by vegetation, unlike the medieval defensive castles built on a hill.
