The Caves of Sare Guided underground tour in the heart of the Basque Country

An original exploration of the underground world!

20km from Saint-Jean-de-Luz, in the heart of a remarkable natural and historical area, lies a prehistoric site where the echo of a thousand-year-old human adventure still resonates…

More than just a history or geology lesson, the guided tour of the Sare Caves offers a journey in the footsteps of our ancestors, where emotions mingle with the whispers of the earth. It's an opportunity to grasp and reconnect with the profound bond that unites us with nature, the source of our beliefs and cultures.
The megalithic park and site museum, which are freely accessible, allow visitors to complement the knowledge acquired during the guided tour.

A unique, educational and entertaining experience for young and old, to be enjoyed whatever the weather, indoors and at 14°C all year round!
