Cultural & Natural Hiking in Urdaibai: Painted Forest and Gaztelugatxe

Context The Urdaibai Biosphere Reserve in the Basque Country features a landscape where marshes, forests, and coastline converge. Here lies the Oma Painted Forest, a site-specific artwork by Agustín Ibarrola that transforms trees into visible canvases, viewable only from designated vantage points. The route continues to Gaztelugatxe, a rocky outcrop crowned by a small hermitage accessible via 241 steps. The trail ascends between 200 and 970 meters in elevation, passing through a protected area of deep ecological and cultural significance.

The Experience As you walk, the rough texture of painted bark invites touch, revealing abstract forms emerging from the woodland. The wind carries scents of pine and salt from the Cantabrian Sea. The path continues upward toward Gaztelugatxe, where the sound of crashing waves accompanies the demanding climb to the hermitage. From this vantage point, panoramic views of the Cantabrian coast contrast with the quiet stillness of the surrounding forest.

For Whom This hike suits individuals in good physical condition, families with children over six years old accustomed to moderate walks, and nature or art enthusiasts seeking immersive cultural experiences outdoors. It is not recommended for those with limited mobility, fear of heights, or who cannot book access in advance.

Local Context Urdaibai holds deep cultural and ecological roots. Ibarrola’s artwork in the Painted Forest reflects a harmony between art and landscape, while the hermitage of San Juan de Gaztelugatxe serves as a historical and spiritual landmark for the local community, preserving traditions and fostering respect for this protected environment.
