February 13, 2026, Climb from Asteasu

I confirm how pleasant that route is, and you can even extend it by going up to Eernio.

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.

A few meters before we have a bar-restaurant at the foot of the road. At this point we also have a water source.

The Mirandaola park is a haven of the history of Basque iron. It is home to the old traditional forge where you can see how iron was worked in the 19th century. In addition, there are various buildings and structures where iron is the protagonist.
