Run through the marl caves

UNIQUE EXPERIENCE

Each lap an 800m loop through the caves

The marl quarry of Kanne is one of the most beautiful and authentic limestone quarries, with a total network of passages extending to no less than 16 kilometers. It is a pristine and original underground landscape with high passages, reaching over 8 meters in places. Enjoy the silence (spectators not allowed in the caves) and the coolness (12°).
