The Urdazubi Urdax caves, located in the northern region of Navarre near the French border, are a significant geological and historical site. Formed over thousands of years by the erosive action of the Urtxuma River, these limestone caves feature an intricate network of galleries adorned with stalactites, stalagmites, and other karst formations. The constant humidity and temperature within the caves contribute to the preservation of these natural formations, making them an exceptional underground landscape.

In addition to their geological interest, the caves have been a site of human activity for millennia. Archaeological excavations have revealed evidence of human presence dating back to the Paleolithic period, including tools and remains that suggest the caves were used as a shelter by prehistoric groups.

Later, during the Middle Ages, the caves became associated with local legends. The people of Urdax believed that the caves were inhabited by lamias, Basque mythological creatures similar to sirens, who lived in rivers. The lamias gathered in the Reception Hall, located right at the entrance of the caves. It is believed that the good state of preservation of the caves is precisely because the people of the village did not enter the caves for fear of the lamias.

Today, the Urdazubi Urdax caves are open to visitors, offering guided tours that explore their geological features and historical significance. The visit includes a carefully lit route through the main galleries, allowing visitors to appreciate the impressive rock formations while learning about the cave’s past.

Nearby, the town of Urdazubi Urdax and its historic monastery provide additional cultural attractions, making the caves an essential stop for those exploring Navarre’s natural and historical heritage.
