The caves of Sare are carved into Atxurio mountain, an immense limestone deposit in Sare. The Leza cave is practically in its original state of 2 million years ago. The cave occurs in an atypical geological formation. Immense spaces, an entrance porch amongst the largest in Aquitaine, and also traces of our ancestors’ lives.

The 900 metre path features sound and light animations. The guided tour lasts 45 minutes and teaches you about the geological characteristics of the site, its qualities as a habitat for the last 10,000 years, the mythology surrounding life in the cave, and the origins of the Basque people.

There is also a museum on site, where you can learn more about human evolution from prehistory to today. You can also learn about the works of J. M. Barandiaran, eminent Basque prehistorian and ethnologist
