We drive to El Estrecho de San Gines. It is a town linked to the mining exploitation of these mountains, historically
abandoned and forgotten. At present time seems to have stopped here. The ancestors of these people worked hard to extract minerals from these mountains.
From the northern part of the town there are several trails that go up the hill, and allow to see the remains of mining activity. You have to be careful because some mines are not covered and you run the risk of falling inside. It is convenient to follow the trails.
