Urkiola is a mountain range of the Basque mountains in Biscay near Durango, in the western Basque Country, Spain. The highest mountain in the range is Anboto (1331 m). The range runs from west to east and forms the water divide between the Atlantic and the Mediterranean basins.
It was declared natural park on 29 December 1989 prompted by the Basque government's determination to protect the diversity of wildlife and flora it harbours. In the center of this natural park is a church called Santuario de Urkiola. This is the church of both Saint Antonio Abad and Saint Anthony of Padua. It stands out as one of the most beautiful and visited Basque churches.
Basque mythology is also present in this natural park. Tradition holds that a cave perched on eastern side of the Anboto mountain holds the abode of Basque goddess Mari.
