Train cost from Lauterbrunnen to Wengen

It is 13.60 CHF roundtrip. But if you are going to spend time in Switzerland, best learn to use the SBB website to find prices yourself.

Www.sbb.ch

https://www.sbb.ch/en/home.html (This is in English but not working right now).

Note that the website defaults to the price with Half Fare Card, so you have to double what it shows, unless you can get the "keine Ermassigung/no reduction" button to work (I never can).

On SBB, you now have to fill in passenger name and age before you use the No Discount button. That's obviously a hassle if you're just looking up a price.

For this particular region, this page of Jungfraubahn works the opposite way, defaulting to No Discount.

Also, if you have Rick's Switzerland book, the graphic on p. 129 displays prices for different legs within the Lauterbrunnen Valley.

Thanks for the information!
