Looking for a nice day trip (by train) outside of Milano to see countryside. Suggestions appreciated.
Certosa di Pavia or Bergamo would do it for me; or, Como and the lake.
I would be heading north to Lake Comp and/or Lugano
Another vote for Lake Como or Lake Maggiore.
You can take the train to Varenna on Lake Como or to Stresa on Lake Maggiore. Travel time will be an hour each way for either of these destinations.
Enjoy!
