Zegama, popularly known as "the shadow of Aizkorri", is a town and municipality in the Goierri region of the province of Gipuzkoa, in the autonomous community of the Basque Country, northern Spain.

The southern Otzaurte hamlet (IPA: /o'tsaurte/) stands on the dividing line of the waters running onto the Mediterranean watershed and those flowing north to the Atlantic through the Oria river.

Pilgrims exit the town heading south up the slopes, so reaching the San Adrian tunnel after 5 km, where backpackers and hikers may gain access to the plains of Alava, the Urbia fields or the summits of the rugged Aizkorri mountain range.

Cattle, especially sheep, graze on the sides of the mountainous terrain, following a tradition of millennia, as attested by old traces and megalithic vestiges that bear witness to the activity.

The grazing provides the basis for the production of the much appreciated and highly regarded Idiazabal cheese elaborated and labelled as such on the whole Aizkorri-Aratz area and the Basque mountains.
