Parque Ornitológico de Mendixur is a interesting birdwatching destination in the Basque Country and an essential stop for ornithologists visiting inland Euskadi. Located on the shores of the Ullíbarri-Gamboa Reservoir in Álava, the park forms part of a protected wetland ecosystem internationally recognized for its ecological importance.
The wetlands of Mendixur were created after the construction of the reservoir in the 20th century, but over time they evolved into an exceptionally valuable habitat for aquatic birds and migratory species. Today, the area is included in the Ramsar Convention list of wetlands of international importance and is also protected within the Natura 2000 network.
For birdwatchers, Mendixur offers excellent observation opportunities throughout the year. The wetlands attract a great variety of species thanks to the combination of lagoons, reed beds, flooded meadows, forests, and open water. Depending on the season, visitors may observe herons, great egrets, little egrets, grebes, ducks, marsh harriers, kingfishers, cormorants, and numerous migratory birds stopping during their journeys between northern Europe and Africa.
Winter is especially appreciated by birdwatchers because of the large numbers of overwintering waterfowl, while spring and autumn migrations can bring surprising sightings. Early mornings and sunset are usually the best moments for observation.
One of the main attractions of the park is its excellent infrastructure for wildlife observation. Several wooden hides and elevated viewpoints allow discreet birdwatching without disturbing the fauna. The walking trails are flat and accessible, making the area suitable for relaxed walks combined with photography and observation sessions.
The park is located close to the recreational areas of Garaio and Landa, making it easy to combine birdwatching with cycling, hiking, or a visit to the reservoir beaches. Parking areas and picnic facilities are available nearby.
