The Organbidexka Pass, an exceptional observatory in the Basque Country

Immerse yourself in the heart of the Iraty Forest, the largest European beech forest that reveals the Organbidexka Pass at an altitude of 1,300m. Grassy pastures, rocky ridges, heather moors, and torrents— the landscapes are incredible and diverse depending on the season, with colors that change throughout the year. Keep your eyes peeled for breathtaking views of the Haute-Soule or the Eastern Piedmont, and don't forget to look up to observe the unique ballet of migratory birds between summer and autumn each year. Meet between Saint-Jean-Pied-de-Port and Tardet, at the Iraty chalet, which is the starting point for many hikes, including the one leading to the Organbidexka Pass.



Bird migration, an event not to be missed at the Organbidexka Pass

The dates are easy to remember: between July 15 and November 15. This is when you can observe thousands of migratory birds leaving their breeding grounds to reach their wintering grounds between southern Spain or Africa via the Strait of Gibraltar. The invitation to this natural and privileged spectacle is the opening of a study program of the autumn migration of birds across the Pyrenees, a daily monitoring that extends from sunrise to sunset. Free and open to the public, the site allows visitors to observe a multitude of migratory birds including raptors, cranes, storks and pigeons. The presence of the LPO Aquitaine makes it possible to identify the birds, analyze their behavior and understand the importance of protecting these species. Experience an unforgettable moment at the Organbidexka Pass.


Info : The daily news of the observer team is published every week during the migration study period on the LOP Aquitaine Facebook page .
