This area was a mining complex, the Mutiloa mining district, from the late 19th century. In 1911, 162 miners worked there, and in 1912, 34,500 tons of iron ore were stored and washed. After being transported by rail to Ormaiztegi, it was shipped to European steelworks. (https://www.mutiloakomeatzaritza.eus/es/la-via-verde/)

The Ormaiztegi Viaduct (inaugurated on August 15, 1864) is the town's most emblematic symbol. Designed by engineer Alexander Lavalley, a predecessor of Gustave Eiffel, it stands in a beautiful landscape overlooking the Eztanda River. It is the most important structure on the Madrid-Paris railway line, spanning 289 meters in length and 34 meters in height. Its 18,000 tons are supported by four pillars. The double track was installed in 1912 and electrified in 1928. It is currently disused and forms part of the Basque Country's cultural heritage.

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.

Great tour always along the river and through countless tunnels. Also recommended in hot weather. Bring light if possible.

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.
