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.
As a memory of an old livestock farm is the Field of Libarache, located just less than one hour of easy walk from this point of Gallinero. A large pasture with the pastoral cabin (current refuge) and the old cattle references welcome the walker who, continuing up the slope would reach the hill of Horquín (1.585 m) from where the two Camerano counties and the summits of Cebollera and Demanda can be seen. The meadow, currently surrounded by beech forests, tells us about the cattle past of the region, at the time when it was a very important site of the transhumant pastoral activity and from where, every year, they descended to the pastures of Extremadura (Spain).
