Aizarnazabal is a town in the region located closer to the sea. It is bordered to the north by Zumaia, to the southeast by Zestoa and to the east by Aia. This small village of 800 inhabitants is located about 29 kilometres from Donostia. Aizarnazabal has gone from being a rural town to one having a very strong industrial network. Even so, it is surrounded by a stunning landscape and it has managed to maintain its personality for centuries in its history. In terms of its cultural heritage, its bridges stand out, above all, the only Old Bridge with six arches in Gipuzkoa. Moreover, it has a great historical importance, as in the olden days it served as a nexus between the country houses of Aizarnazabal and Zestoa. The San Miguel church, Etxabe Palace and Etxabe Goikoa country house are other buildings which are well worth a visit.
The main festivities are celebrated at the end of September coinciding with the feast day of its patron saint, San Miguel (29 September).
