La Boucle des Sompes

Between the wells and the butterfly washhouses that line the large sinkhole in the village ofEscamps and the woods of truffle oaks, this walk will allow you to discover the intimacy of the Causse de Limogne-Lalbenque.
150 million years ago, a great sea covered the area. Sediments were deposited on its abyss, creating layers of limestone rock which, when the sea receded, were subject to erosion and dissolution by the effect of rainwater. Chasms, caves, dolines (“basin” of dissolution) were thus formed. Ouvalas is the name given to large sinkholes or sinkholes that "join".
