The geological aspect, formed above all by schist, granite, limestone and volcanic trachyte, has determined the variety of coasts. We pass quickly from a high coast with cliffs on the sea to a coast with "rias", full of bays and promontories that delimit wonderful beaches.
How could we forget
Cala Coticcio in
Caprera, Cala Corsara and
Cala Granara on the island of Spargi, the Pink beach on
Budelli island or Porto Madonna, a piece of turquoise sea enclosed by the islands of Budelli, Santa Maria and
Razzoli, with its lily-white
Spiaggia del Cavaliere.
Beauty does not end here but continues in
Costa Smeralda with 55 km of coast exploited by
Aga Khan. Tourist pressure does not affect much the clearness and beauty of the sea during the months of July and August. The sea regains its beauty during the other months of the year thanks to currents and a strong North West wind (known as Maestrale) that sweep away all impurities and give oxygen to the waters. Going South from
Olbia, after the wild promontory of
Capo Ceraso we reach
Coda Cavallo that stretches towards the islands of
Tavolara and
Molara, the heart of the homonymous natural sea park. From here in the distance we can see the beaches of Brandinchi and Lu Impostu and from there carry on to
S. Teodoro and reach the fantastic beach of
La Cinta.
