Kortezubi is a town that has preserved an extensive landscape, ecological and cultural heritage. It was chosen by our ancestors as a home and resting place in pre-historic times. They were attracted, certainly, by the abundant resources and the comfort of its numerous caves. Proof of that is the Santimamiñe cave. It has a landscape that is open towards the estuary and compact in the inland valleys with trails and routes that will immerse you in an exceptional landscape.
