A pleasant walk on the shores of Lake Lugano allows to explore the peninsula of Caslano, a typical Ticino village, dominated by a hill of 500 meters. The natural scenery is fascinating because it offers, on a limited territory, a significant amount of botanical varieties representative of Ticino. Specifically for this reason this area is protected by the Swiss Confederation. Also from a geological point of view this strip of land between Lugano and Ponte Tresa is of particular interest, as it presents different types of very old rocks from different eras.
