You need to ask Sicilians which are the best beaches in Sicily. They change every year, not only because of who goes to them and how clean they are, but because nature works fast on this triangular island. There’s a beach near me that was twenty yards of soft sand last summer: this year its ten feet of pebbles.
Unlike your guide book, this website called “The most beautiful beaches in Sicily” is always up to date. Just follow the link below. Every beach on it is gorgeous, but Sicilians can constantly vote beaches up or down.
