Outdoor Activity · Hidden Gem
Aiako Harria in Basque or Peñas de Aya in Spanish, is a massif east of the town of Oiartzun in the Basque Country. The river Oiartzun rises on its north-western face.

The range is very popular with the inhabitants of the area. Other neighbouring towns are Irun on the north and Lesaka on the east. The massif comprises three summits extending 4-odd kilometres north to south in a row, namely Irumugarrieta (806 m), Txurrumurru (821 m) and Erroilbide (837 m). Its characteristic shape can be made out approximately from as far as Bayonne (north), the massif being dubbed the "face of Napoleon" on account of its similar outline, while its actual French name is Les Trois Couronnes. At its western foot, the mountain holds the site Arditurri related to ancient Oiasso with a network of mine corridors carved in the rock and put down to Romans. Some notable mountains around are Bianditz (827 m) on the south, Jaizkibel (547 m) on the west and Larrun (905 m) on the north-east.

  • From the top of Penas de Aya, one dominates all the bay of Hendaye-Hondarrabia- Irun. It is quite easy to find, as it is indicated on the road signs in Irun. There are several trails, a lot of options available. Better to have the gps or a good map. On a fine day the views are gorgeous. To reach the very top is quite technical and requires a bit of climbing; most of the hikers just go around. For a shorter hike, one can drive to Elurretxe gap then only 300m elevation remains.
  • Absolute Saturday hike. 3-4 circled tour with basic climbing required. 20-30 min from San Sebastian.
