That bridge is called "INTUIA-ko zubia" the INTUIA farmhouse is next to it. The misnamed "witches' bridge" is called UNANIBI-ko zubia, right in the Otita park (beginning of the Leitzaran valley). Don't forget to bring lights to cross the numerous tunnels in this valley!! Not to see but to be seen.

Small and charming fishing village located between the Gipuzkoan coast, the mountain of the Pagoeta Natural Park and the mouth of the Oria river. This beautiful villa has a beautiful historic center, better known as Goiko Kale. An authentic labyrinth of streets dating from the 12th century. Among its main attractions is the baroque church of San Nicolás de Bari and the hermitage of San Martín de Tours.
