A source of fear and wonder for millennia, Mount Etna is a mighty 10,900-foot (3,320m) active volcano on the east coast of Sicily. In fact, it’s one of the most active stratovolcanoes in the world, and centuries of lava flows have formed the dramatic landscapes that surround it: all cinder cones, summit craters and steep slopes. The 19,237-hectare uninhabited site around the volcano was named a UNESCO World Heritage Site in 2013 thanks to its global scientific importance.
