It has a spectacular reddish-colored landscape and strangely-shaped, clay-like mountains, where the Romans of Legio VII (in the first century) extracted gold using basic methods, mainly hydraulic energy. They took the water from the snow that accumulated in the mountains and launched it at great pressure take out the surface layers of land, leaving the precious gold nuggets in sight. When the gold was in deeper layers of the mountain, they caused cracks in the earth, forming caves that can still be seen.

The best place to see this landscape is from the Orellán viewpoint.
