It is located in a wide river bend of the Flumendosa, the Sardinian river with the greatest flow of water and, along with its tributary, Stanali, it characterizes the hilly landscape, covered in forests of cork oaks, holm oaks and Mediterranean scrub. Ballao is a village with 800 inhabitants in the historical region of Gerrei, on the border between southern Sardinia and Barbagia. The river landscape is its great attraction: between unusually shaped rocks and enchanting natural pools, in a setting of rich vegetation, you can observe grey herons, pheasants, mallards, European bee-eaters and, in the river waters, turtles and eels. Near the village, you can visit the Cortirosas mine, now a symbol of industrial archaeology and part of the Geo-mining park of Sardinia. Antimony was once extracted here, while today you will see the ruins of the washing area, flotation system and electrical generator.
