Spiaggia Sotto Torre, Sand beach in Calasetta, Italy.
Spiaggia Sotto Torre is a sheltered sandy beach spanning roughly 700 meters along the southwestern edge of Sant'Antioco island. The shore has fine light sand and calm Mediterranean waters that slope gently into deeper areas.
This beach grew tied to tuna fishing practices that began centuries ago and shaped Calasetta's founding as a settlement. The maritime economy that developed here continues to influence the area, with fishing vessels still operating from the nearby port.
The name Calasetta refers to a small port, reflecting how fishing shaped the town's identity and daily rhythm. People gather at this beach as part of their connection to the sea and local maritime life.
Public parking areas are available near the beach, and the town center with shops and dining options sits within 500 meters walking distance. The wide shoreline makes it easy to find a quiet spot during the day, especially in early morning or late afternoon hours.
The waters here contain high mineral concentrations from ancient geological layers, creating a distinctive blue-green hue visible across the surface. This mineralization comes from underground geological processes that occurred beneath the island over millennia.
