The Urdaibai wetlands, located within the Urdaibai Biosphere Reserve in Biscay, Basque Country, form one of the most valuable ecological areas in northern Spain. These tidal marshes, estuaries, and coastal habitats are a vital resting and feeding ground for thousands of migratory birds that travel each year between Europe and Africa. Their exceptional biodiversity and scenic beauty make Urdaibai a reference point for conservation and ecological research.
Among the most emblematic areas are the Orueta marshes, Kanala estuary, and the sandbanks of Laida, where herons, egrets, spoonbills, and various raptors can be seen throughout the seasons. Spring and autumn migrations are particularly impressive, bringing a remarkable diversity of birdlife to the reserve. Even outside migration periods, the wetlands offer changing landscapes and wildlife encounters that reflect the rhythm of the tides and seasons.
To help visitors appreciate and understand this unique environment, the Urdaibai Bird Center serves as a research and observation hub at the heart of the wetlands. Established in 2012 in a restored traditional farmhouse overlooking the Orueta marshes, the center provides exhibitions, guided visits, and viewing platforms equipped with telescopes for observing the birds without disturbing them. It also plays an important role in ongoing ornithological research and environmental education.
The center is accessible by car from Bilbao in approximately 40 minutes. From Gernika, follow the BI-2235 road towards Gautegiz Arteaga, where clear signs direct visitors to the center. Free parking is available on-site. For those using public transport, Gernika is well-connected by bus and train, and the center is a short taxi ride from the town.
The best times to visit are during the spring and autumn migration seasons, when the highest diversity of birds can be observed. You can watch the realtime Urdaibai webcams to check current conditions and visible species near the Bird Center. You can also check the observation log on eBird website.
