The rivière souterraine

Navigating under the earth…

An incredible crossing along the Rivière Plane. The journey takes you from one hall to the next, within vertical fissures dug out over the last two million years…

How strange it feels to go forth in the calm of the depths, at the whim of the calm, serene river, ensconced at the bottom of this stunning crater. A boat ride in the stunning silence of the chasm, looking on the incredible spectacle of erosion in the underground world.
