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.

Beautiful town nestled in the Guipuzcoan valley of Alto Urola. The name of the town comes from Basque and means 'place of the elm'. The Urola River runs through the town and separates it from the municipality of Urretxu. Zumárraga is also the end point of the Urola greenway, a cycle route that runs through a beautiful rural landscape. A destination with a lot of charm and personality.
