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.

Tips from the Community
The first (or last section if reversing the route) section is absolutely NOT accessible. Possibly only at extreme low tide. We were there an hour before extreme low tide, and it was completely impossible. I would choose to simply follow the route at a higher elevation and skip the "beach" section. Especially since the beach is made up of large stones and rocks, difficult to walk on because you always have to watch your step due to loose stones.

Mostly the area is windy especially due to topography. Do not forget to carry water with yourself. Enjoy the Bay of Biscay

The Oma Forest - Omako basoa in Basque - is also known as the painted forest, the enchanted forest or even the Ibarrola Forest. Its most common name - Oma Forest - refers to the district in which it is located, which belongs to the municipality of Kortezubi. This original work of art was created between 1982 and 1985, when the Basque painter and sculptor Agustín Ibarrola used the trunks of trees as a kind of canvas for a total of 47 images. On them he painted animals, geometric figures and people, or just parts of them, such as eyes and lips. In addition, many of the compositions do not consist of a single tree, but must be viewed in the context of several tree trunks. To do this, you must pay attention to the signs on the ground that tell the viewer where to stand in order to enjoy the whole image.
