Zurich to Lauterbrunnen to Venice

I just went to www.sbb.ch/en and put in Lauterbrunnen to Venezia S. Lucia and got a solution (among others) at 7:32 which got me to Venice at 2:24 pm for 85 CHF on June 5. That is a train specific nonrefundable ticket.

Do you want scenic or fast? The SBB website referred to you earlier will show you the most efficient. For scenic I would go Lauterbrunnen - Chur - Bernina Express - Tirano - Milan - Venice. This can't be done in one day, however, and requires an overnight stop in Chur. It was worth it to ride the Bernina Express. https://www.seat61.com/BerninaExpress.htm

The easiest thing for you to do is go to the ticket counter in Zurich (airport or main station downtown) and ask for tickets to Lauterbrunnen. You can either buy your tickets also from Lauterbrunnen to Venice while at the ticket counter in Zurich...or just wait until you are in Lauterbrunnen and then to the ticket counter there and purchase your tickets. It's as easy as easy can be if you do it that way.

Thanks for the info! So these are individual train tickets you're recommending? Not a fast pass? If we want to take the train in Lauterbrunnen a few times, will it still be a better idea to buy individual tickets?

I'm not familiar with Swiss rail passes, so can't advise whether point-to-point or passes are better. I can say that the Bernina route would be covered by a Swiss pass as far as Tirano (after that, you're on the Italian rail system). If you already have a pass (or a ticket), then all you need from Bernina Express is the EUR 10 reservation fee for the Chur-Tirano leg.
