This stretch of coast is renowned for its crystal clear water, golden sands and long beaches. It also has a lake system that forms a nature reserve
for rare avian species. Costa Rei is bordered by the bays of Sant'' Elmo
to the south, and to the north by Capo Ferrato, a nature reserve where no construction is allowed. Even a brief visit to Costa Rei is unforgettable thanks to its pine groves, a Roman staircase leading down to the sea, lovely maquis, strange and wonderful marine rock formations and Ferraxi’s sandy bays and offshore islands.
The loveliness of the beach
changes with the shifting light at various times of day. The sun rises over the flat and motionless sea, which glitters in an ethereal bluisy grey light. The colors of the sea are at their most intense at noon. The luminous hues vary from turquoise blue to emerald green in waters where the seabed 20 meters below the surface of the water is clearly visible. This fine sandy beach is dotted here and there with rock formations that give way to rocky bays at Sant'' Elmo
and Capo Ferrato and extend to Villasimius and the island of Serpentara, creating a captivating panorama.
