Origin and history
The Basque Corniche (Euskal Erlaitza in Basque) is a natural site of 445 hectares, extending over the communes of Ciboure, Urrugne and Hendaye (Pyrénées-Atlantiques). This coastal landscape, shaped by flysch cliffs, coves and rocky spurs, is home to pastures, forests and vineyards, while under pressure from climate change and marine erosion. The Corniche road, inaugurated in 1912, runs along this coastline for 6 km, connecting the port of Socoa to the beach of Hendaye, but its route is now threatened by accelerated collapses, with a planned disappearance by 2043.
In the 19th century, the Corniche became a strategic issue with the construction of a railway (Bayonne-Spanish border) and, in 1925, a tram line linking Socoa to Hendaye, boosting local tourism. During the Second World War, the German occupation included works of the Atlantic Wall, particularly between the peaks of Socoa and Saint Anne. Today, the site, classified Natura 2000, combines remarkable biodiversity (marine protected areas, coastal lawns) and historical heritage, such as the domain of Abbadia, castle-observatory designed by Viollet-le-Duc for explorer Antoine d'Abbadie in 1864.
The Corniche is also a place for various human activities: sheep farming (Manex sheep farming), viticulture, fish farming, and recreation (surfing with the Belharra wave, golf, ULM). Since 2020, surveillance measures (preventive closures, 24/7 instruments) have been put in place by the Departmental Council and the agglomeration community Basque Country to limit erosion risks. The coastal trail, once accessible, is now partially prohibited because of the landslides, such as the one that occurred after the storm of October 29, 2020.
The Abbadia estate, managed by the Coastal Conservatory and the city of Hendaye, attracts 250,000 annual visitors with its trails, its orchard of local fruit varieties, and its castle mixing medieval, eastern and Ethiopian influences. In Urrugne, Corniche is also home to public infrastructure (water treatment, waste disposal) and sports equipment (golf practice, shooting club). The Basque Littoral CPIE organizes educational activities to raise awareness about the preservation of this fragile coastline, subjected to rising waters and Atlantic storms.
