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.

Nice segment that is part of the beautiful 37-kilometre route along the old railway line that linked Pamplona with San Sebastián. The path stretches through the green valleys of northern Navarra and offers stunning views of the Pyrenees and the Basque coast. Ideal for a family outing.

Tolosa is a jewel of the Basque Country that stands out for its historical, cultural and gastronomic heritage. Its old town, the Plaza Nueva, the medieval bridge and the Parque de Aranzazu are some of its main attractions. Tolosa is also an excellent starting point to explore the surrounding nature, with beautiful mountains and trails.
