If there is such thing as infinite stars, Rosario deserves them all! He is super knowledgeable, funny,, and flexible. It was like touring with a family member (to whom your are endeared). From the moment he picked us up, Rosario shared not only incredible information; but also his love of Etna itself. He is a true master of his craft and is a must not miss should you be on the Etna side of Sicily. Should we return to Sicily in the future, we will definitely take a tour with Rosario again! Bellissimo!
