i need to book a train from venice to wengen in june. what train should i take?
At minumum, your talking 4 train changes and 7 to 8 hours. Change in Milan, Spiez, Interlaken Ost, and Lauterbrunnen.
Ditto Sam. Your routing will be Venice/Milan/Spiez/Interlaken Ost/Lauterbrunnen/Wengen. You will change trains at each location. On some runs, you may have an extra train change at Brig. Only the Swiss can sell you the entire ticket. The Italian Trenitalia can't see Lauterbrunnen or Wengen on their screens. Interlaken Ost is as far as they can see.
