San Pedro cave

The San Pedro Cave is situated beside the Santa Maria Church and the Town Hall in the district of Axpe. The explored length measures approximately 3,000 meters in depth. The mouth of the cave measures 4 meters in width and 2.3 meters in height. According to a study on mammals carried out in the Urdaibai Biosphere Reserve, there are five species of bats: miniature horseshoe, large horseshoe, Geoffroy, Schreibers and Mediterranean horseshoe. All these species are considered fragile with one in danger of extinction. Measures taken in order to provide protection to these bat colonies were to install a metallic fence, as well as closing the cave to the public from February to June.
