It is located in the basin of the Baztán-Bidasoa being bathed by the calm flow of the river Bidasoa as it passes through Oieregi. Back in the 14th century the first references to the Señorío de Bertiz appeared, the estate was privately owned and managed until in the 20th century it passed into the hands of its current manager, the Diputación Foral de Navarra, who in 1984 declared it to be the current Señorío de Bertiz Natural Park that it is today. An excellent example of the diversity that characterises the Cantabrian valleys of Navarra, its relative isolation from the uses and customs of the area, thanks to the private management of its resources, contributed to creating and maintaining the varied habitat of great ecological interest that characterises it and which has earned it the status of a special conservation area within the Natura 2000 Network.
The Señorío de Bertiz along its entire length offers innumerable attractions that invite you to visit it. Nature lovers and hikers have an extensive network of trails, which run through the park visiting its beautiful corners. Trekking routes such as the Iturburua path or the Suspiro path allow hikers to adapt the route to their preferences as these two routes join the Irretarazu path and the Plazazelai-Aizkolegi path, known as the Way of the Straw, both longer, thus allowing a beautiful circular route with the level of demand we want.
But the Señorío de Bertiz Natural Park also has its centenary Historic-Artistic Garden waiting for us, a true jewel of nature in which not only does the careful ornamentation stand out, but also the diversity of both native and exotic species that we have to meet as we walk along its ways and cross the paths that cross the garden. Sequoias, lemons, yews, hydrangeas or bamboos are carefully intermingled with the native species of the Bertiz Garden. We must also visit its interpretation center, where we can get a broader idea of the history and characteristics that accompany the Señorío de Bertiz, as well as visit its botanical garden..
Of all the plant species in the Señorío de Bertiz Natural Park, many of which are true treasures, there is one specimen that stands out for its own merit, the Cedar of Bertiz. This Cedrus Libani is a species typical of the Mediterranean mountainous areas. Also known as the cedar of Solomon because its wood was chosen for the creation of its temple, this specimen was declared a Natural Monument by the Government of Navarre and it is not only surprising because it has grown outside its usual habitat, but also because of its peculiar shapes and its particular dimensions.
Legend has it that in the past in these lands it was not difficult to find, deep in the valley on the banks of the river Bidasoa, some of the lamias that lived here. With their comb and their golden mirror they combed their long hair while they sang beautiful melodies, leaving all the men who observed them enchanted by their charms, preventing them from loving other women. For these reasons, the women of the villages of the area undertook a bloody hunt of lamias that decimated them until almost disappearing. Today, if we observe attentively and listen in silence, hopefully we will be able to discover some of the lamias that were saved or that returned years later to the valley where they lived.
