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.

The route connects again with the PR-NA 201 at the milestone where the Vertical Kilometer appears on the right, continuing straight through the panoramic mountain meadow to the popular hermitage of San Donato. Part of the sanctuary is converted into a mountain refuge and is delicious when there is a blizzard or bad weather, as was the case the day we did the route. The geodesic vertex of Beriain is next door, on the rocky tip of a cliff that concentrates the kingdom of abysses and cliffs that float above the towns of the Sakana.

The Lareo reservoir is located in the Aralar Natural Park, near the border with Navarra. It is a small swamp and is surrounded by beech and larch trees, which take on bright colors in the fall. The tour starts from the Parketxe de Lizarrusti interpretation center.

The Labeo dolmen is located near Lareoko urtegia, and Malkorburu. Of religious or funerary origin, it belongs to the Neolithic, Chalcolithic-Eneolithic and Bronze periods.
