How to get Bernese Oberland Pass for more than 10 days?

1) yes, you will have to buy multiple passes. Or get the HFC and just buy tickets for some of your trips.

2) If you have a pass you do not need a ticket. So why are you trying to buy a ticket?

I always wished the BO Pass would offer even longer stays - even up to a month. Please take note that there are also critical route changes and additions to the BO Pass that started in 2015. So with that said, you have three options, and all involve the purchase of the Swiss Half Fare Card (SHFCard), which basically pays for the BO Pass via the discount received:

OPTION 1: For the first two days and the last two days, you only use the SHFCard and try to plan the sights and higher-cost gondola/train usage around this option. Then, on the core 10 days in between, you go for it and plan out the heavy BO Pass usage. The SBB train app is so cool and so easy to use for instant purchases once you get the hang of it.

OPTION 2: You purchase an additional amount of BO Pass days to cover the entire 14-day journey. NOTE the weird quirk that an 8 and 6-day BO Pass purchase is less expensive than a 10 and 4-day purchase ($ 91 dollars saved per adult over and above SHFCard savings).

OPTION 3: You split the passes up something like 8 days BO Pass and 6 days Jungfrau Pass and plan out the sights that are now not on the BO Pass that are on the Jungfrau Pass, like a train from Wengen to Kleine Sheidegg, First Gondola, Schynige Platte, Eiger Express Gondola. By the way, the total cost of this option is less than Option 2 above.

Hope this makes sense and helps.

We have done exactly that in the past: bought two sequential passes to cover our entire stay.

Last year in a 24 night stay I noodled out the benefits of the Unlimited Summer Jungfrau Pass https://www.jungfrau.ch/en-gb/unlimited-jungfrau-summer-pass/#2289 and determined along with our Half Fare Cards it was the way to go. In retrospect, I would probably do so for a 14 day stay as well.

The Unlimited Summer Jungfrau Pass (USJP) has a limited area of coverage so it depends on if you plan to frequently go beyond the Lauterbrunnen-Mürren-Wengen-Grindelwald-Interlaken area. For example, a day trip to Thun or Bern will require tickets using your HFC or possibly Saver tickets, which we used for our infrequent forays beyond the immediate area. The USJP also allows unlimited trips to the Jungfraujoch, if that is of interest. This pass does NOT cover the Golden Pass, however. Saver Day Passes may prove economical for that journey.

For the two of us, we saved about 500 CHF using the combo of USJP + HFC + Saver tickets. I recommend sketching out what you want to do in a spreadsheet for your own comfort. You have to buy the passes in person as they take your picture as a security measure.

I did not know about the unlimited Jungfrau summer pass. IMO, for us long-stay Jungfrau Region travelers, this is an incredible deal. We sometimes stay in that region for 6-8 weeks at a time. Swiss Half Fare might also make sense because it saves the $ 100 upfront per pass, and I can easily find another $ 20 in savings of other trips not covered by the Jungfrau Pass. Thanks for sharing that information, Laurel!

Typically for a traditional 14 day stay the Unlimited Pass doesn’t work all that well as a substitute for the BO pass. We live in Mürren for the summer so that’s what we get but it’s limited for a traditional tourist (no boats, Oeschinensee, Thun, Brienz, Bern, Montreux, etc) which I’m guessing is important to Carolyn if she’s choosing it over the Jungfrau Pass. It’s a great pass if you’re there long term and plan to stick to the Jungfrau though.

There is a new way that you can extend the BO pass from 10 days to 12 days for an extra 60 chf and will probably be best for you. Get the half fare card and plan out your use of the pass so that your 2 non pass says are at front/back or all front loaded for your least expensive trips. To get the 2 day add on you have to go to a train station on the last day of validity to add on the 2 days, there is no way to do it in advance (dumb, I know). If your plan is to take the Golden Pass Express on your 14th day, then you’ll just need to use your half fare card only on day 1 & 2. Depending on where you’re staying, just plan simple activities for those 2 days that don’t involve a ton of public transport and use your half fare card to get 50% off.

Eddie - we live in Mürren for the summer and get the year long half fare card + Unlimited JP since the month long isn’t long enough. The Unlimited JP started out during COVID as the “Corona Pass” and since locals/long term visitors loved it so much they kept it. It’s been a game changer for us in what we spend on transportation for the summer.

Wandereg,
So you purchase the summer-long Jungfrau Pass and the Swiss Half Fare Card and stay in Murren the entire time? Makes sense to me - wow. Are there any issues with the train conductors checking the 3-month long summer JP pass with the one-month validity of the Swiss Half Fare Card?
Staying in Murren as you do, the only things not covered with the summer JP pass are the Allmendhubl funicular, the Gondolas to Gimmelwald/Stechelberg, and, let's say, some buses down in the valley. But those things are so inexpensive, so should I assume you simply purchase those when needed? I am so glad I found out about this summer JP pass. I owe all of you a $ 50 hamburger/french fry/drink meal at Flavours Cafe in Lauterbrunnen (yes a joke about food costs in the area - ha).

Are there any issues with the train conductors checking the 3-month long summer JP pass with the one-month validity of the Swiss Half Fare Card?

Yes, they watch for that. We were in-country over 30 days and had to buy a second HFC.

Just to be clear, the USJP covers these. The regular Jungfrau Pass does not. In case anyone reading this thread is confused.

Thank you for suggesting all these options! I should have said we are staying in Wengen for the 14 nights so expect to use that train a lot in both directions to get to hiking trails - that's what we are mainly doing, so I know we can also hike from Wengen to some places, so having some non train days might work...

We are taking the Golden Pass on our way to the Bernese Oberland, but just taking the regular trains back through Lausanne and on to Paris - maybe should consider the Golden Pass both ways since it is free with BOP.

You would have been better off buying the year long HFC then. Since you are basically behaving as locals. You do not have to be Swiss to buy that. All you need is an address where they can send the little red card (confusingly called "Swiss Pass") to.

Yes, you are correct, Eddie. We spend our summers living in Murren and get the year long HFC + unlimited summer pass. It was a bit of a hassle to get our year long HFC the first time, as they don't make it very intuitive to get it as an American and we ended up having to do an online chat with an SBB employee for them to manually override the issues we were having with it. But now that we're in the system it just automatically renews every year.

The Unlimited Jungfrau Pass is different than the Jungfrau Pass with different validity (see map here - www.jungfrau.ch/en-gb/unlimited-jungfrau-summer-pass/) . It includes the Schilthorn, Jungfraujoch, Gimmelwald, etc. all at 100% - it’s really meant for locals, as it’s the only pass in existence that completely covers Jungfraujoch, etc. (not that I use it for that, I stay away from Jungfraujoch at all costs, haha!)

In regards to the Half Fare Card - they are only concerned that you currently have a valid half fare card on that day when they are checking your pass, there is no requirement to show one that covers the entire summer (it's day by day validity), but for some reason they literally never check our half fare cards with our summer pass. My guess is because it’s more of a locals pass that isn’t geared towards tourists, they know that you have what you need for it. If you do decide to get it, you can purchase online, you'll get an email and then you go to a local train station to pick up your physical card (it will have your photo ID attached to it in their system).

We do take trips beyond the validity zone from time to time (Thun, etc.) and then just pay half fare for those trips, not a big deal. But 95% of your time is spent hiking and just living in the areas around Murren, so the pass covers us for pretty much everything we do, including our big grocery hauls in Interlaken.

I'll take you up on an expensive burger anytime! Haha! Our favorite is the local mountain burger at the Alpenblick in Murren :)

They actually occasionally ask me to show the HFC with the Summer Pass. However you also get the reduction if you previously had a ski pass, and so in theory I could dispense with the HFC as I get a ski pass (for a reduce price, as I am a local :-) ) every year as well.,

But I travel enough around Switzerland that I get the HFC. In

There are about 3150000 people with the HFC in Switzerland. There are also about 500000 with a GA. Which shows how popular public transport usage is in Switzerland.
