Swiss Travel Pass Question

If you haven’t yet bought your train ticket for Bern to Paris, then you likely should get the Swiss Travel Pass because Bern to Paris can run anywhere from $100-$180. With the Pass your train travel is covered within all of Switzerland, except for private railways. This also is the case with the Swiss Flex-Pass The TGV train ticket from Geneva to Paris can cost as little as $46 if you buy it now.

Aside from accessing Wengen—If you’ll be wanting to take the Jungfraujoch or the gondolas/cogtrains up to the Schilthorn or Grindelwald First — then you’ll want to see if the Berner Oberland Pass pencils out.
First Glacier is a spectacular hike. So is the simple Gimmelwald to Murren flat hike looking directly across the Lauterbrunnen Valley towad the Eiger Monch and Jungfrau mountain peaks.

With the Pass your train travel is covered within all of Switzerland, except for private railways.

That is not correct. Many railways in Switzerland are private companies and they all take the Swiss Travel Pass. The rule is that the pass is only valid to inhabited towns and villages. So it is valid to Wengen, an inhabited village, but only gives a 25% discount from Wengen to Kleine Scheidegg because Kleine Scheidegg is a largely uninhabited location for hiking and skiing. The railroad from Interlaken Ost to Wengen, Kleine Scheidegg and the Jungfraujoch is all privately owned by the Jungfraubahn Holding Company.

The Berner Oberland Pass is only valid on the route from Domodossola to Interlaken Ost using the older route via Kandersteg, since that is privately owned by the BLS Railway, a private company, while both that route and the route via the Loetschberg Base Tunnel are valid with the Swiss Travel Pass.

Yes, it can be complicated figuring out the ideal pass strategy, especially now that the Berner Oberland Pass coverage area has changed this year. It is no longer valid to Grindelwald First, and covers Wengen to Kleine Scheidegg and the Jungraujoch at 50%.

Sam, Thank you for the correction on private trains.
I’m thinking since the Swiss Pass covers 50% of the Grindelwald to First Cable Car, 25% of the Jungfraujoch train and the train to/from Grindelwald & Lauterbrunnen, along with the train to Geneva— the Swiss Travel Pass is the way to go.
What do you think?

Maybe look at the Jungfrau Travel Pass, which covers the Firstbahn, as well as all the lifts and rails between Wengen and Grindelwald, including Kleine Scheidegg and Maennlichen. For the Jungraujoch, the Connecting Ticket gives a round trip from Eigergletcher for 75 CHF. You get a discount on the Jungfrau Travel Pass with the Swiss Travel Pass.

If i do the Jungfrau Travel Pass, and combine it with the Swiss Half Fare, I am thinking that the savings i get from getting the expensive trains up to Jungfraujoch and Grindelwald First might offset the trains in and out of the Jungfrau region.

However, when reading the JTP site, it says that "Eigergletscher - Jungfraujoch return at the special price of just CHF 63/CHF 75"

What does this mean?

Is it possible to get up to these two locations for free on this pass?

It is 63 CHF in the off-season and 75 CHF June 1 to Aug 31 from Eigergletcher to Jungfraujoch. It is free to Eigergletcher.
