Arkù indicates the arched shape of the summit that, when seen from Piscinas and Scivu, looks like a dolomitic tower. The mighty Monte Arcuentu, a popular trekking destination, is part of a mountain range that runs parallel for eight kilometres to the beaches of the wild and wonderful Costa Verde. It is part of the territory of Arbus, which is eleven kilometres away, and it is near the Montevecchio mines, once the economic reference point of the area and today an open air museum of industrial archaeology. From the summit of Arcuentu, the horizon disappears before your eyes: you will admire landscapes of the nearby mountains of Arci and Linas, from the gulf of Oristano to the Costa Verde and from the valley of Campidano to the peaks of Montiferru, Sette Fratelli and Gennargentu.
