3Mount Etna, Italy

Mount Etna, located on the island of Sicily, is one of the most active volcanoes in the world. Standing at over 11,000 feet (3,329 meters), this UNESCO World Heritage site regularly erupts, spewing lava and ash into the sky. Despite its volatility, Mount Etna is also a popular tourist destination, offering visitors the chance to witness the power of an active volcano up close.

Hiking around Mount Etna’s craters and lava fields provides a unique opportunity to experience the raw power of geological forces. The contrast between the fertile soil, which supports vineyards and orchards, and the barren lava landscapes is a testament to the duality of nature’s destructive and creative forces.
