Tips from the Community

January 2, 2026, Ormaiztegi Viaduct

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.

From the port of Mandubia, located 532 meters high, there are magnificent views of the Arriarán reservoir surrounded by green mountains. There is a restaurant right next door.

The lords of Igartza built this service center in the 16th century and increased their wealth. This magnificently preserved monumental complex, in addition to the palace-house of the lords, has: a hermitage, a mill, a forge, an apple press, a dovecote, the shoemaker's house and the blacksmith's house, among others. The visit is worth it.

The historic center of Ordizia is very well preserved and has several buildings that have earned it the declaration of a historical-monumental complex. In addition, its market of typical products has been celebrated since the 11th-12th centuries and its spring Idiazabal cheese market is highly recognized.

The Lareo reservoir is a small reservoir in a beautiful environment. The sheet of water creates a beautiful visual game with the dense forest that surrounds it.
