The Covarones of the Tuernes River are a whimsical karst landscape formed by the natural erosion of the limestone by the river's action over centuries. At the end of its course, for almost half a kilometer, the river submerges three times, alternating between underground sections and open-air stretches surrounded by a riverside forest. Within this forest lie the remains of two old mills and even a Paleolithic cave, the Nora refuge. This geological phenomenon is a karst formation in the Carboniferous mountain limestone, which has given rise to an underground river with characteristic limestone formations such as caves, arches, stalactites, whimsically shaped stones, and windows in the ceiling resulting from the collapse of the vaults and the action of the water.
