Starting at the northernmost point of Sicily, this route primarily follows the island's entire east coast, passing some of the most breathtaking historic cities, mountain crossings, majestic cliffsides, both white and black sandy beaches, and prominent structures originally erected by the ancient Greeks thousands of years ago. And then there's Mt. Etna, Europe's most active volcano, visible for much of the route. You can literally watch as smoke billows from the top all throughout your attempt.
