Up until 1940, minerals were mined and loaded onto ships here. Like an authentic open-air industrial museum, CalaDomestica, two kilometres south of Buggerru, still preserves the ruins of warehouses, deposits and tunnels dug by the miners. One of these to the right of the cala leads to a second, hidden, almost intimate cove known as La Caletta.
The larger cove is a deep and stunning inlet, almost a fjord, with a wide, sheltered beach with soft, compact sand that ranges from white to amber and gold. Small Mediterranean bushes dot the dunes behind the stretch of sand. In front, there is one of the most beautiful, turquoise and azure seas of Sardinia.
