Beaches and sea
The approximately 13 km of Castiadas coastline begin south of Costa Rei, with the secluded Santa Giusta beach in the Santa Giusta plain, best known for the massive turtle-shaped rock overlooking its waters, known as “Peppino’s Rock.”
Continuing along the coast, past a holiday resort, the hill of Monte Turnu protects the stunning Cala Sant’Elmo, made up of alternating rocks and small sandy inlets. Immediately to the south, you’ll find Cannisoni beach, where the deserted countryside behind it maintains a strong and evocative environmental character, and the golden San Pietro beach (Cala della Marina). A little further south is Cala Sìnzias, a magnificent beach at the foot of a brush-covered group of lonely coastal hills.
Continuing further south towards Villasimius, you reach the beautiful Cala Pira; the beach features white sand and transparent waters where a flat valley meets the sea. On the promontory, the well-restored 18th-century Cala Pira tower overlooks the coast. Among the beaches in the area, we must certainly mention:
Cala Pira beach 400 m long, this is an enchanting cove overlooked by the Spanish tower of the same name. It is surrounded by a pine forest and embellished by surfacing rocks that face a crystal-clear sea. The fine sand is mixed with smooth white pebbles.
