Although you have to make a slight detour, it is worth visiting this bridge and taking a photo on it if you want.

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.

The beautiful building of the old Urola de Azcoitia train station is currently used as a library. One of its rooms is decorated with old railway sleepers. In the back there is a bike mechanic and washing station.
