This beautiful city located in the valley of the Oria River is surrounded by small mountains and green meadows. Thus, it offers you the possibility of escaping from the noise of the city in a few minutes. Furthermore, in its historic center is the church of San Martín de Tours, which is undoubtedly worth a visit.

Aia is located on the central Gipuzkoa coast, between the coastal towns of Orio and Zarautz. Located 30 km west of Donostia - San Sebastián, the urban center of The Hague is 10 km from the coast. Its orography is rugged, ascending from north to south, with elevations such as Pagoeta, Indamendi, Andatza, Eztenaga, etc.
