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.

If you like sheep cheese, you are in the right place. Idiazabal is the headquarters of the shepherds' council that brings together the producers of the famous cheese of the same name. Here you can visit the Idiazabal cheese museum and learn much more about this dairy delicacy.

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.

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.
