The Italian boot is fringed with nearly 5,000 miles of coastline – from the sandy beaches of the Adriatic Sea to the sinuous gulfs and dizzying cliffs of the Tyrrhenian. Add to that more than 400 islands, and you have a beach lover’s paradise. This portfolio of hotels includes historic monasteries and Belle Époque villas, exotic masserie and cliff-top resorts with private beaches and thermal pools. On the mainland coasts or the Mediterranean islands, all are in spellbinding settings. From Sardinia to Sicily and Positano to Puglia, here are the best beach hotels in Italy.
