This area is one of singular beauty from different viewpoints; from the geological viewpoint, with its remains of marine animal fossils, more than 300 million years old, from the botanical viewpoint, with its extension of beech and oak trees in the basins of the rivers that cross it, from the historical viewpoint, due to the remains that have been preserved from the main historical events and from the leisure viewpoint, due to the recreational areas and walks.
We take the concrete track that begins next to the information booth and, after about 30 meters, we walk on the dirt track that goes to the right.
Along this path, which runs parallel to the road, we pass through a recreational area set in an old beech tree nursery and arrive at the Gorostardi car park. At the beginning of the track that starts on the left of the road, there is a signpost.
Following the direction of “San Anton” we continue to the next signpost located at the crossroads of Erroiarriko lepoa.
From here, we can optionally climb up to Erroiarri crest (be careful when passing by the electric tower. DO NOT TOUCH!) from where we can enjoy magnificent views of Endara valley, Aiako Harria and the surrounding mountains. Following the marked route, from the crossroads take the track on the left towards Erlaitz. The path passes through sections of mature oak woods and open areas where new trees have been planted to regenerate the forest.
We will cross several streams bordered with alders. After crossing a small pine grove we get to a concrete track. We take this track to the right, cross a small car park next to a farmhouse and take the dirt track on the left.
We continue along this track until we reach the ridge that descends to Endarlaza. Here we turn left and go uphill along the path that goes up to Pagogaina meadows. We continue between pastures and bushes. Sheep, cows and mares graze freely in these open areas and it is easy to observe vultures and other birds of prey. We cross a small larch grove and pass by the ruins of Pagogaina Fort (19th century).
The path descends until it reaches the starting point again, where the milestone of “La Pena de Vida” (The death penalty) is located. It was placed in the 17th century as a warning: “From here, desertion leads to death penalty”.
