The Picos de Europa karst massif represents the main concentration of deep caves of the World. Nevertheless, Picos de Europa also includes shallow caves with many kilometres of conduits, where new passages are discovered ever year. Among these new passages involve1.7 km of conduits discovered in the El Hayéu del Osu Cave System, which length reaches 3.5 km. Its vertical range was increased up to 226 m since the discovery of a new upper entrance named Torcana.
