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.

This spectacular path through the beech forest is just a small sample of the incredible beauty of Aralar. The path runs pristine under the forest and, in some sections, looks out like a balcony from the cliffs.

Spring and autumn are generally the most pleasant seasons for mountaineering in Ataun, offering mild temperatures and vibrant landscapes.
