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.

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.
