Spiaggia di Santa Giusta, Sandy beach in Costa Rei, Sardinia, Italy

Spiaggia di Santa Giusta is a beach in the Costa Rei area of Sardinia, in the province of Cagliari. It lies on the island's south-western coast, about 400 km from Rome. The climate is mild, with an average temperature of 18 °C and rainfall of about 801 mm per year.

The coastal area served as a natural anchorage point in ancient times and held importance for early settlements. Archaeological findings confirm human activity dating back to prehistoric periods, showing the long connection between this shore and human habitation.

The beach takes its name from the nearby church of Santa Giusta, a landmark of the Costa Rei stretch. In summer it fills with Italian families who arrive with umbrellas and coolers and stay through the afternoon, while the shallow entry makes it a common first swimming spot for children.

Parking spaces are available near the beach entrance and rental services for umbrellas and lounge chairs operate from several points along the shore. A restaurant is located at the facility, and the wide, flat sand makes it easy to walk and find comfortable spots.

A whale-shaped rock formation called Scoglio di Peppino sits at the northern end, accessible through shallow water for those wanting to explore. The formation creates natural swimming pools and draws attention from visitors looking for something beyond the usual sandy beach.
