Mario holds a degree in Agricultural Science from the University of Catania. After many years working as an agronomist, he decided to transform his passion for nature and trekking into his full-time job and became a licensed naturalistic guide in 2004. Since then, he has gained extensive knowledge and experience, and none of Sicily's natural beauties of Sicily is unknown to him, including, of course, Mount Etna, the Madonie and Nebrodi mountain areas. Throughout the winter, he dedicates himself to skiing and snowshoes hiking on Mount Etna.

Alessio holds an advanced degree from the Institute Montana Zugerberg in Switzerland. He lived in the Swiss mountains for many years, where he developed his love and passion for nature. Upon his return to Sicily, his homeland, he began studying the Etna, practiced climbing, and attended various training courses BLS and BLSD. Alessio is also a certified sommelier from the prestigious Associazione Italiana Sommelier.

A Taormina native, Guglielmo is a professional guide certified AIGAE (Associazione Italiana Guide Ambientali Escursionistiche). An off-road instructor with a NCC driver license, Guglielmo is also a fine photographer. His passion for photography leads him to continuously explore new facets of Etna and other areas of Sicily, and this feeds his inspiration to explore and share unknown or little-known hikes with travelers.
