A spectacular full day combining the Phoenician-Roman ruins of Tharros on a dramatic sea peninsula with the extraordinary quartz beaches of the Sinis Peninsula, including Is Arutas, Mari Ermi, and San Giovanni di Sinis. The area is part of a Marine Protected Area with some of the clearest water in Sardinia.
The Sinis Peninsula on Sardinia's west coast pairs ancient ruins with some of the island's most unusual beaches, and a car is essential to link them; the area lies about 100 km northwest of Cagliari and only 20 km from Oristano. The headland is part of a Marine Protected Area, which keeps the water exceptionally clear and the development low. Tharros, on a narrow spit at the southern tip of the peninsula, was founded by the Phoenicians around 730 BC and grew into a Roman town; its excavated streets, Punic tophet, Roman baths, and standing columns spread over a hillside above the sea, with the Spanish-era Torre di San Giovanni crowning the ridge for wide views. Entry is around €5. Nearby, the village of San Giovanni di Sinis preserves one of Sardinia's oldest churches, a small early-Christian basilica. The peninsula's beaches are the other half of the day. Is Arutas is famous for its sand of tiny quartz grains, smooth and rounded like rice, ranging from white to pale pink and green; Mari Ermi and Maimoni nearby share the same clear, shallow water. Collecting the quartz sand is forbidden and fined, to protect a resource that took millennia to form. A sensible plan tackles Tharros in the cooler morning, when the shadeless ruins are most bearable and the light is good for photography, then moves to the beaches for swimming and lunch in the afternoon. Adding the Civic Museum in nearby Cabras is worthwhile to see the Giganti di Mont'e Prama, the remarkable larger-than-life Nuragic stone statues. The Cabras lagoons on the way are a good place to spot flamingos, and the town is known for its bottarga, the cured grey-mullet roe served over pasta in local restaurants. The beaches are at their best from May to October, while Tharros can be visited year-round. There is little shade anywhere on the peninsula, so a hat, sunscreen, and water are needed, and the quartz beaches have few facilities, making it wise to bring supplies.

When to visit
The quartz beaches are best from May to October, while Tharros is open year-round. Mornings suit the exposed ruins, leaving the warmer afternoon for the sea; shade is scarce throughout, so sun protection is essential.
