Zurich to Lauterbrunnen for 3 nights then Italy

Hi, We are travelling from Australia,flying into Zurich.We need to catch a train to Lauterbrunnen where we have booked 3 nights. We will then travel to Italy by train. We would like to go up to Jungfrauch or Stilthorn from Lauterbrunnen. What would be the best pass for us ( married couple).
We will be buying a Eurail pass for Italy as we will be travelling by train.
Please help as im confused.

Thanks , When we leave Lauterbrunnen we are headed straight to Lake Garda via Milan NOT back to Zurich so would this pass still be ok?
We are looking at a Eurail Select pass to include Switzerland which I thought included travel in Switzerland but then we would have to still purchase tickets for the mountain trips?
Its sounds like no matter where you go in Switzerland you need one of these passes???

Hi Dianne,

Yes, you can use the Swiss Card to travel to/from the airport or the Swiss border (Domodossola in your case). The inbound and outbound leg do not need to be the same. All Swiss Card details & prices can be found on the Swiss Card page.
You do indeed need a pass as mountain trips without a pass are quite expensive. A Eurail Select Pass includes at least 3 countries and offers less discount on the Jungfraujoch. It's most probably more expensive than the Swiss Card.

Ok thank you for your help.As Im unsure if our flight will arrive on time from Australia will I need to book the train trip to Lauterbrunnen or can we just turn up and get on the next one ??
Counting down the day to see your amazing country.Thanks again.

Hi Dianne,

Swiss trains don't need to be booked. You can just board with your pass. Here's more information.

I see the Swiss card has a big difference in price between 1st and 2nd class. IS there much difference between the two.
As we are first timers to Europe we wont know the difference anyway?? Thank you for your help.

Hello Dianne,

The difference is explained here.
