The old, abandoned copper mines resemble a lunar landscape: a strange and fascinating stage, illuminated by the reflections of copper-hued lakes. A road cuts through the landscape, guiding you along dirt roads. Streams and wells glow in unlikely colors, from copper to green to deep black. Signs warn of the dangers of the water, but nothing prevents your gaze from losing itself in the dramatic and unsettling beauty of the place.
