Aiako Harria Natural Park


Tourism destinations


Oiartzun is located in the northeast of the historical territory of Gipuzkoa, a few kilometres from the sea, within the Oarsoaldea region, next to Lezo, Errenteria and Pasaia.

The river Oiartzun flows through the town. The town has one of the widest surface areas in Gipuzkoa, part of its lands belong to the Natural Park of Aiako Harria, formed by granite mountain range.

Six neighbourhoods constitute the area: Ergoien, Karrika, Altzibar, Iturriotz, Ugaldetxo y Arragua. The main urban area is situated in the Elizalde neighbourhood on the right bank of the river.

The old quarter and Arditurri Greenway

The old part of the town is home to many interesting buildings such as the parish church of San Esteban de Lartaun, with a retable from the 17th century declared cultural asset, and the basilica of San Juan Bautista, dating back to the 16th century. Another way to enjoy Oiartzun is to stroll along the Trail/Greenway known as "Arditurri Greenway" which departs from Pasai Antxo and Lezo, through Errenteria, and which only pedestrians and bicycle users can access.

Nowadays is linked with the San Sebastian Bike Route. The Arditurri Greenway takes us on a trip through the area's varied landscape and even brings us to two unique museums in Oiartzun: The Luberri- Geological Interpretive Centre and Soinuenea-Herri Musikaren Txokoa- Centre for Popular Music. The Greenway trail ends at the Arditurri Mining Reserve, where we have the chance to visit the mines that have been worked for 2,000 years.

The town achieves its most splendour at San Esteban's patron Saint festival from 2nd August to 6th.
