Oñati, Guipúzcoa - Gipuzkoa (1)
Where the highest peaks of the Basque Country can be found
Guipúzcoa and Álava, in the Basque Country, share the Aizkorri-Aratz Natural Park. Located to the south of Guipúzcoa and to the north of Alava, together with the Sierra de Aralar, it constitutes one of the ecological corridors that unites the Pyrenees and the Cantabrian Mountains and also separates the historical territories of Alava and Gipuzkoa. This area includes a long mountain range where the highest peaks in the Basque Country are located, Aitxuri 1551 m and Aizkorri 1544 m. The Aizkorri, which has on its summit a hermitage dedicated to the Holy Christ, next to the Aratz, gives its name to the Aizkorri-Aratz Natural Park which extends through the Álava municipalities of Aspárrena, Zalduondo, San Millán and Barrundia and by the Guipuzcoans of Salinas de Léniz, Eskoriaza, Aretxabaleta, Oñati, Legazpia, Zerain and Zegama, as well as the land corresponding to the Parzonería General de Guipúzcoa and Álava.
The abrupt limestone crests, which testify to its geological value, such as the rocky wall of the Aloña-Aizkorri-Aratz, contrast with the rounded hills and siliceous hills covered with vegetation. Ridges and hills that have a common denominator, its substratum formed by reef limestone, also known as urgoniana, whose erosion gives rise to dolinas, torcas, ravines... places as famous as the Hoya de La Lece, the tunnel of San Adrián, the depression of Urbia or the ravine of Arantzazu. This spectacular place is completed by beautiful beech and oak forests as well as extensive pasture plains, such as in the Urbia valley. Human presence also left its unchangeable mark on the megalithic monuments. Dolmens, tumuli and monoliths from thousands of years ago are intermingled with hermitages and farmhouses, resulting in an interesting historical-architectural heritage added to the Aizkorri-Aratz Natural Park.
With a total area of 19600 hectares, the beautiful Aizkorri-Aratz Natural Park is a true paradise for hikers, mountaineers and visitors wishing to enjoy the history and culture that it keeps in hidden corners while its beautiful landscapes flood its retinas. Mountain routes and hikers that hide, in their tours, places as historic as the tunnel of San Adrián, mythical passage of the ancient medieval road that linked Flanders with Castile.

Since time immemorial, the Parzonería General de Gipuzkoa y Álava has existed in the Aizkorri-Aratz Natural Park. This is an uninhabited local entity whose surface area has been completely declared Public Utility Forests in which the neighbouring municipalities have the sole function of administering their territory in accordance with their statutes. For this reason, and since ancient times, grazing, charcoal and many other activities have left their peculiar stamp in the area.
The declaration of Aizkorri-Aratz as a Protected Natural Area in the category of natural park was in 2006. Likewise, the European Commission included it in 2004 in the list of Sites of Community Importance (SCI) of the Natura 2000 Network. The main entrances to the Aizkorri-Aratz Natural Park are in Zegama and the Arantzazu Sanctuary near Oñati, in Guipúzcoa. While in the province of Alava its main accesses are in Zalduondo and Araia.
Reaching the summit of Aizkorri is a goal for mountaineers who enter the Aizkorri-Aratz Natural Park. This is the magical peak of a hermitage which, according to legend, houses a miraculous Christ. This Christ, no matter how much the people of the place insisted, to protect the image, in lowering it to the temple of Zegama or to that of Araia, always reappeared at the top of Mount Aizkorri.
