In a magical environment, made of rock and fantasy, you become a child again. The grottoes of Is Zuddas, in the territory of Santadi, open up 236 metres below sea level in the cambrian limestone, dating back to 530 million years ago, of Monte Meana. They extend over a total of 1650 metres, while the visitable tourist itinerary is half a kilometre long. Each of the rooms stands out for its size and the variety of concretions covering cavities and walls: from stalactites, stalagmites, flows and tubular formations to aragonites, symbol of the caves, the formation of which is still a mystery and is the object of research.
