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.

The Lluera caves are two small natural cavities (sometimes the denomination Cueva de la Lluera is used for the main one, ignoring the small one, and from the archaeological point of view Cueva de la Lluera I and Cueva de la Lluera II) . They contain prehistoric representations of the Paleolithic, which are found in the parish of San Juan de Priorio, in the municipality of Oviedo, Asturias (Spain). Archaeological remains from the Solutrean period (21,000 to 17,000 BP) and the final Upper Magdalenian have also been found. The first associated with part of the engravings. https://es.wikipedia.org/wiki/Cuevas_de_la_Lluera
