Admire these 100-metre-high cliffs that stretch nearly two kilometres. They are 15 million years old. The cooling lava flow at the origin of the site formed these immense columns called "orgues", certainly in reference to the musical instrument. This flow, once at the bottom of the valley, was brought to the surface by the action of erosion, and is therefore in "inversion of relief". These cliffs are home to a large population of Red Kites.
