On the east coast of Sicily, one step closer to the strait of Messina, you will find Mount Etna, the tallest active volcano in Europe.
Through the centuries, the eruptions have modified the volcano’s slopes, drawing a unique views of lava and ice, now protected by a big natural reserve, that you may visit walking through peaceful naturalistic trails.
Climbing to the top you will pass across different landscapes: from the fruitful countryside of sweet citrus plantations to the thick forests, from the bare landscapes, where the  broom perfume reigns, to the lunar landscape nearby the crater.
From the higher points, you may enjoy a spectacular view that extends until the island of Malta.
At night time during the eruption, the view of the river of lava, that slowly flows along the wall of the Etna, it's striking.
Of great interest is also the Bove Valley, a huge natural amphitheatre whose walls are carved from deep canyons and may reach the height of 1000 meters; there is  also the Ice Cave 'Grotta del Gelo', an imposing volcanic cavity where it took form the only exemplar of perpetual glacier at this latitude.
Another spot not to miss is the one of the "Gole dell'Alcantara", shaped  throughout the centuries, by the erosional action of the cold water of the homonymous river.
Etna being the symbol of the region, it is a fundamental stop for these who choose this land to spend their holidays and moreover during the winter, when the snow covers all the scenery, it becomes an ideal site for skiing.
