Running the 25km length of the Costa del Sud, this panoramic road – known more prosaically as the SP71 – snakes along the spectacular coastline between Porto di Teulada and Chia. It's a stunning drive whichever way you do it, with jaw-dropping views at every turn and a succession of bays capped by Spanish-era watchtowers.
Starting in Porto di Teulada, the first stretch twists past several coves as it rises to the high point of Capo Malfatano. Along the way, Spiaggia Piscinni is a great place for a dip with incredible azure waters.
Beyond the cape, the popular Cala Teuradda beach boasts vivid emerald-green waters, summer snack bars and a conveniently situated bus stop.
From here the road climbs inland away from the water. For great coastal views, turn off along the narrow side road at Porto Campana and follow the dirt track to the lighthouse at Capo Spartivento. From here a series of beaches stretch north – watch out for signposts off the main coastal road to Cala Cipolla (a gorgeous spot backed by pine and juniper trees), Spiaggia Su Giudeu and Porto Campana.
At the end of this stretch you'll see another Spanish watchtower presiding over Chia, the small resort that marks the end of the road.
