Casalarreina is located on a wide alluvial plain. The municipality is irrigated by the River Oja, an especially important river for the area because it gives its name to the Autonomous Community of La Rioja. Said river’s presence means the existence of a diverse and rich landscape in the municipality, the surrounding area covered by wide fields of crops contrasting with a characteristic riverbank woodland, home to the most important green spaces in Casalarreina.
Magnificent views of some of the region’s most characteristic landscapes and natural resources can be enjoyed from our municipality. Our Zaballa panoramic viewpoint offers unique views of the Obarenes mountains and Gembres and El Toloño peaks.
