Inland from the Basque Country, 30 minutes from the Basque coast, St. Martin d?Arberoue: in the Colline de Gaztelu, 600 meters of galleries, the Grottes d'Isturitz and Oxocelhaya. Unravel the mysteries of human history told in the present.
A benchmark in Europe, with 80,000 years of documented human presence. A single guided tour for both caves: the Isturitz cave, an archaeological site and parietal engraving, and 15 meters below, the Oxocelhaya cave, a surprising natural curiosity, with concretions dating back thousands of years. A magical underground world, a cathedral of time.
