Enjoy a breathtaking hike from Francavilla di Sicilia through the uncontaminated nature of the Alcantara Gorge. Following a pick-up at your accommodation, admire the beauty of this canyon of volcanic origin carved by the incessant flow of the river. Start making your way towards Gurne, a series of natural lakes formed as a result of volcanic phenomena. Along the way, see the archaeological excavations of a Greek settlement dating back to the 5th century BC. Next, come across the ruins of the ancient Norman castle of Francavilla di Sicilia. Admire the Saje, a system of innovative pipelines introduced by the Arab people that made agriculture prosperous. Towards the end of the hike, see the Ciappa Mill where the first attempt to produce hydroelectric energy was made in the 17th century. The mill played a key role in making Francavilla and Castiglione the first villages in Italy to have electricity. Conclude the day by returning to Catania.
