BA-4

On the road from Lekumberri to Uitzi. At km 2.7 a track branches off to the right. Going along it and past an iron gate, about 100 metres from the road, another track branches off to the right. We go up it until we come to the ruins of what was once an old miners' lodging. From there we continue towards the mine and, without reaching it, on the right, on the slope, we see a wall at the edge of a small depression.
