En uno de sus valles recorrido por el río Iregua, está el Camero Nuevo, tierra de bosques, pastizales, cumbres y pequeños valles, donde se sitúan 13 pueblos con historia, tradiciones y leyendas, que siglos atrás se agruparon bajo la denominación de Hermandad de las 13 Villas.
Cave Lóbrega is about two kilometres far from Torrecilla. This cave was one of the first to be studied, from a scientific point of view, at the end of the XIX century and evidence of having been inhabited since the Neolithic era have been found. Its 455 meters long and its galleries of stalactites and stalagmites offer visitors the opportunity to enjoy a unique adventure.
To access it, it is recommended to use specialized material and an experienced guide.
