Parque natural de las Peñas de Aya
Peñas de Aya is one of the oldest mountain ranges in Guipúzcoa, within the Peñas de Aya Natural Park. It is found between the towns of Oyarzun, Irún and Lesaca (Navarra). They are mountains with very special characteristics, because they were not created by orogeny but by granite intrusion. From this massif you can enjoy magnificent views, which is why the area was classified as a natural park, along with Mount Urdaburu. Google Maps
