Selva de Irati (Irati Forest)

The Selva de Irati (Irati Forest) in the high Pyrenean valleys of northern Navarre is one of the largest and best-preserved beech-fir forests in Western Europe, covering approximately 17,000 hectares across the border between Navarre and the Basque Country. Accessed primarily via the Valle de Salazar from the village of Ochagavía, the forest unfolds across rolling Pyrenean terrain at elevations between 700 and 1,400 metres, threaded by the Irati and Irabia rivers and framed by the artificial Irabia reservoir. The forest floor is carpeted with moss, ferns, and wildflowers in spring and summer; in late October, the canopy turns gold and rust in one of the most dramatic autumn foliage displays in Spain. Marked walking trails range from short 2-kilometre lakeside loops to full-day routes crossing into France via the Collado de Organbidea pass. The Casas de Irati visitor area near the reservoir serves as the main base, with parking, picnic tables, and an information point. Wildlife includes Pyrenean deer, wild boar, and a small brown bear population that occasionally crosses from the French Pyrenees. Birdwatchers find black woodpeckers, honey buzzards, and dippers along the river. The forest road from Ochagavía is gated from approximately November to April due to snowpack, making spring through autumn the accessible season. A half-day minimum is recommended; a full day allows deeper exploration of the valley circuits.
