Olvera is a town in the province of Cádiz, Andalusia, Spain. According to the 2005 census, the city has a population of 8,585 inhabitants. Overview At the tip of the "White towns route", the city of Olvera is in the province of Cadiz, in the northwest of the Serranía Gaditana area, near the borders of the provinces of Seville and Malaga, on 36º56' north and 5º16' west, at a height of above sea level and has a land surface of .

Of great interest within the municipality is a large colony of Andalusian griffon vultures (Gyps fulvus) to be found within the natural reserve of the "Peñon de Zaframagón", a huge rock outcrop that is located 14 km to the northwest of the town centre.
