Urkiola Natural Park – Limestone Peaks, Forested Valleys, and Mountain Pastures

A mountain landscape shaped by stone, woodland, and Basque rural traditions

Urkiola Natural Park protects one of the most distinctive mountain landscapes in the Basque Country, forming a natural transition between inland plains and the Atlantic-facing valleys. Limestone peaks rise above dense woodland and upland pasture, while historic paths and rural tracks cross the park between villages such as Otxandio and Durango. The GR® 38 Wine & Fish Route passes through this terrain, linking vineyard landscapes with the coast across wooded slopes and mountain passes.

This is a landscape shaped by geology and elevation. Pale limestone ridges and rocky outcrops rise above beech and oak forest, while open pastureland supports traditional baserri farmsteads and seasonal grazing. Paths climb steadily through woodland before emerging onto exposed slopes and high viewpoints, where the scale of the surrounding mountains becomes clear.

Despite its rugged appearance, the park feels lived-in rather than remote. Historic farmhouses, small chapels, and grazing land reflect long-standing patterns of land use, while the Sanctuary of Urkiola beneath the Anboto massif marks an important cultural and spiritual focal point within the landscape.

Walking in Urkiola Natural Park is defined by contrast. Shaded forest trails give way to open ridges and limestone summits, while valleys provide sheltered routes between upland passes. Terrain is more demanding than coastal sections of the Basque Country, yet rewards steady progress with wide views and a strong sense of mountain environment.

Beyond walking, the park supports nature-focused exploration. Woodland habitats shelter diverse wildlife, seasonal wildflowers colour upland meadows, and shifting light across limestone cliffs creates striking photographic landscapes.

Whether crossing the park on a long-distance route or exploring shorter mountain walks, Urkiola Natural Park offers one of the Basque Country’s most compelling upland environments.
