I will be visiting Lake Como on an upcoming trip. My itinerary takes me from Padua to Varenna via Milano Centrale. Later I’ll leave Varenna for Florence, again via Milan. My questions are these:
1) Do I buy a round trip ticket in Milan for the trip to and from Varenna?
2) While in Varenna I wish to day trip to Chiavenna beyond the north end of the lake. It is the same tracks, but is it the same train service?
3) And where do I get those tickets?
4) Is there a change of trains in Lecco between Milan and Varenna?
Thanks
