If you have a car then it's very convenient to go to the beaches of
Sicily. Public
transportation is little bit hard but you can rent a car. Marina di Ragusa in one of the less crowded beach and the other one is Donnalucata. The most crowded periods are Easter and Christmas, normally July and August are the less crowded time in recent years. Marina de Regusa is also a lovely quiet beach, but very windy. My favourite beach is Vendicari, Pachino, one of most beautiful beaches of Sicily. It's a wonderful natural oasis in the Siracusa province and hope you will also enjoy this place.
