A route through the Santa Ana hill in Puertollano where we can enjoy exceptional views of the city and the valleys of the Ojailén and Tirteafuera rivers. We will also see the entire Puertollano coal basin with its open-pit mines. Along this magical hill, we can see the Chimenea Cuadrá (Square Chimney), an old telegraph tower, the Natural Bridge with its cave paintings, the cistern of sour water, the Guerrero cave, and the walls of the medieval fortress.
