The primary lake that straddles the border between Italy (near Milan) and Switzerland is Lake Lugano (Lago di Lugano). While Lake Como is closer to Milan and Lake Maggiore also sits on the border, Lake Lugano is uniquely "entwined" with both countries, with about 63% of its surface in Switzerland and 37% in Italy. The lake is famous for its "glacial" finger-like shape and the stunning town of Lugano on the Swiss side, which is a major financial hub. Another significant lake in this region is Lake Maggiore, which is the second-largest in Italy; its northern tip reaches into the Swiss canton of Ticino (specifically the town of Locarno), while its southern shores are easily accessible from Milan via a one-hour train ride. For travelers in 2026, these lakes are often visited as part of the "Grand Tour of Switzerland" or as day trips from Milan. Lake Lugano, in particular, offers a unique blend of Italian "dolce vita" culture and Swiss efficiency, making it a favorite for those who want to experience two countries in a single afternoon boat ride.
