The costal road from Cagliari to Villasimius (about 50 km) is one of the favorite routes for bikers. It is a sequence of marvelous curves overlooking the sea that accompany bays, inlets and ravines beyond obviously beautiful beaches and a sea so crystal clear and transparent to take your breath away. The localities of Mari Pintau, Kala and Moru, Torre delle Stelle, Solanas, Porto sa Ruxi, Capo Boi deserve particular attention.
Once in Villasimius you can visit the beaches of Porto Giunco and Campulongu and, continuing on the coast, the beaches of Punta is Molentis, Cala Pira, Costa Rei and Cala Sinzias.
