The first time you see Mt. Etna, whether she's trailing clouds of smoke or emitting fiery streaks of lava, is certain to be unforgettable. The best-known symbol of Sicily and one of the world's major active volcanoes, Etna is the largest and highest volcano in Europe—the cone of the crater rises 10,902 feet above sea level. Though you'll get wonderful vantage points of Etna from Taormina, Castelmola, and Catania in particular, it also makes a rewarding day trip to see the mountain up close with a hike or climb; you can find routes suitable to every fitness level.
