On the edge of the Gouffre
The karstic landscapes that characterise our region have created places of unimaginable splendour. There's what's visible - the meandering rivers, the visible traces of water flowing over the cliffs and resurgences - but the most impressive thing is what you can't see: what's underground. Everywhere it is tortured by the erosion that over the millennia has forged galleries, caves and chasms. It's an immense Gruyère explored, in tiny parts, by courageous speleologists, who offer you a grandiose and unique spectacle in the places where they have been exploited.
