Hello!
I am hoping that someone on this forum can tell me if there are any requirements/regulations we need to plan for when traveling between Switzerland & Italy (i.e customs or required forms, etc).
We are from the US and will be traveling to Switzerland & Italy. After 2 weeks in Switzerland, we are thinking about taking the train from Interlaken to Milan and then taking a flight from Milan to Palermo. We will then return to Switzerland by flying from Palermo to Zurich. Since we are crossing borders, will we need to do anything special once we depart the train in Milan? Will we have to go through customs (or any type of formaliity) before we board our flight from Milan to Palermo? How about when we fly back to Zurich from Milan? Any information will be greatly appreciated!
