The Col d’Organbidexka, situated at 1,238 m altitude in the Basque Country of France (Pyrénées-Atlantiques), is an outstanding vantage point for observing bird migration. Nestled just 300 m below the Chalets d’Irati and overlooking the Haute-Soule valley with an imposing view of the Pic d’Orhi, the region’s highest peak, this pass lies in the heart of Europe’s largest beech forest.
Between 15 July and 15 November each year, the site hosts a rigorous monitoring programme tracking the autumn migration of birds across the Pyrenees. More than 200 bird species have been documented flying over the pass, many on their journey to Africa. Raptors dominate the spectacle: counts often exceed 4,000 black kites in mid-August, alongside notable numbers of European honey buzzards, common buzzards, common kestrels and ospreys. Other groups such as black storks (Black Stork), white storks (White Stork), common cranes (Common Crane) are also easily observed.
Access is easy by car: from Saint‑Jean‑Pied‑de‑Port follow the route towards Chalets d’Irati, park near the “Restaurant d’Iraty”, then proceed on foot or by vehicle downhill about 300 m to the green hill that marks the pass. The terrain is mountainous and exposed—bring layered clothing and prepare for sudden changes in weather and wind.
The site offers paved paths and an observation platform, and while a telescope is useful, the dramatic migratory flights are readily visible with binoculars. Late summer through autumn is the high season: the wind-driven migration makes the pass a superb natural corridor for birds, offering visitors a remarkable and memorable bird-watching experience in a wild and scenic setting.
