This area is delimited by two important geographical accidents: to the north, separating Rioja Alavesa from the rest of Alava, is the Sierra Cantabria mountain range, which protects it from the humidity, cold and rain from the north; and to the south, forming a natural border with the Region of La Rioja, is the Ebro river, which provides the entrance to a warmer climate from the Mediterranean throughout the valley.
The height above sea level is 451 metres, with an extension of 16 square kilometres. The little vegetation which extends throughout the municipality is of Mediterranean type.
