Como Lake – Cernobbio
 

Milan is a good base for visiting the lakes and interesting smaller cities and towns of the Lombardy region, easily reached by public transportation. The Northern Lakes region can be easily reached from Milan by train. Lake Como can be reached in 50 minutes from Cadorna Station, and Lake Maggiore in 1 hour 20 minutes from Cadorna station. The City of Bergamo, with its medieval center located in the upper town (Bergamo Alta), can be reached in one hour from Milan Central Station. Turin and Venice are also reachable from Milan with normal train or fast “Freccia Rossa” trains. For those who might want to take a trip to the sea, the Ligurian Coast (Genova) can be reached by train in just over one hour.
