Sicilia is the largest island of the Mediterranean Sea, strategically located centrally between Gibilterra and Canale di Suez. The island is predominantly mountainous and hilly, with high coasts on the Tyrrhenian slope, lower and sometimes marshy on the Canale di Sicilia; Mixed on the Ionian Sea. The highest reliefs are in the northeast sector: here is the massive volcanic structure of Etna, the highest in Europe. In addition to Etna, there are active volcanoes Stromboli and Vulcano in the Isole Eolie. Along the coast of the south east end of the island, there are some coastal lakes and ponds.
Of remarkable importance is the city of Messina, which houses an important biosphere reserve as well as cultural heritage, the Isole Eolie, since the UNESCO World Heritage Site of 2000. The area is one of the richest in the island and it is part of two of Sicilia's most important tourist destinations: Taormina and Isole Eolie (Alicudi, Filicudi, Lipari, Panarea, Salina, Stromboli, Vulcano).
