The caves of history
Ojo Guareña, situated in the north of the province of Burgos, is the second largest cave karst formation in the Iberian Peninsula, and one of the ten largest in the world.
This formation is of great speleological interest, as prehistoric shelters have been found here, as well as cave-dwelling invertebrates, including several previously unrecorded species. The formation is of great hydrological, morphological, scientific and even educational importance. It can be admired from various viewpoints including Alto Concha, Retuerta, Pico del Cuerno (on the hiking route). This area is also ideal for practising nature sports.
Ojo Guareña provides a concise insight into the evolution that has taken place from the Middle Palaeolithic Era until the present day; indeed, here visitors will find all the pieces they need to fit this complex jigsaw together. In addition to a wealth of flora and fauna it boasts a rich cultural heritage, bringing together countless attractions in a large natural space.
