EspeleoArrikrutz: Gipuzkoa from a Different Perspective
Have you ever dreamed of venturing into the heart of the earth and uncovering the secrets hidden in the underground world? With EspeleoArrikrutz, you have the chance to enjoy a truly unique experience and feel like a real speleologist in the depths of the Arrikrutz-Oñati Cave, the most extensive cave system in Gipuzkoa.
During a three-hour guided adventure, you’ll explore the most remote and surprising parts of this karst system: active and fossil galleries, passages shaped by underground rivers, and an impressive array of geological formations — including the famous Arrikrutz helictites, which seem to defy gravity.
This is more than just a visit: it’s an immersion into a fascinating, silent, and nearly untouched world where natural beauty and mystery go hand in hand.
