3day swisspass ( valid for a month) have discounts for 8 days cablecars or lakes in interlaken?

Looks like you want the 3 day flexipass with the half-fare adder. That would be 239 chf plus 60 chf for a total of 299 chf per person. Swiss Rail has discontinued the Saver Pass, so you need to buy 2 adult passes.
Since the 8 day Swiss Pass is 363 chf, and it only gives 50% discount on mountain railways, your first option may be the best.

If you are doing that little train travel in Switzerland, it probably isn't worth getting a Swiss Pass. Paris to Interlaken Ost and Bern to Paris can both be bought as one ticket, you do not have to get different tickets at the border. Interlaken Ost to Bern costs 28 Franks.

But, as you say you will not be sitting in Interlaken all the time. You could get a Berner Oberland Pass (click here) for CHF 340 for 8 days which gives free travel on all those routes out of Interlaken which you listed, and extends to Bern, and some more.

I mean all I can do in interlaken, all travels cable cars , lakes.... is a part of my BONOUSES or not? If so , I can buy 3 days flexi pass and use it's bonuses.My 3 days will be first, end day and a day travel to bern. Use bonouses in between.

There are no cable cars in Interlaken, they are all some distance outside.
The map showing what your 3-day Swiss Pass is valid on is here: http://www.sbb.ch/content/dam/sbb/de/pdf/freizeit-ferien/ferien-kurztrips-schweiz/internationale-gaeste/sts-geltungsbereich.pdf
As you can see, it is valid on trains from Interlaken to get you to the bottom of the mountain (Lauterbrunnen, Mürren and Grindelwald for example). Thereafter, if you want to get to the top of the mountains on the cable cars or mountain railways, you get a 25% or 50% reduction. You still have to pay the rest.

The bonus is that you get a 50% reduction on all tickets on other days if you pay CHF 60 extra. You still have to pay ½ price. Details are here.

The Berner Oberland Pass (map here) includes most of the mountain railways, except the Jungfraubahn for which it gives a 50% discount.

I mixed up alittle.at last we must buy 3daysflexi pass or 8 days, if we want to travel ti interlaken, enjoy 8 days there , and come back. 3 days flexi will cover my otherdays between?

sorry, I find your post a little hard to understand.

Can you clarify it a bit, and maybe spend a few words explaining exactly what you wish to do on that part of the trip, and if you want us read a previous post can you say what forum you posted it in and what the name is, please?

ehsanemrani, The 3-day flexi pass only covers the days in between at half price.
Full details are here: http://www.sbb.ch/en/leisure-holidays/holidays--short-breaks-in-switzerland/swisstravelsystem/swiss-travel-pass.html

This is the correct information from Swiss Railways, who sell the card, not what "someone" told you.

Thank you all
Dear Nigel, I have a post in this forum about my travel at 24/07, few weeks ago, with my name:ehsanemrani, Itinerary help.

Dear Chris, as I got, it is better for me to buy a 8 days swiss flexi pass saviour( we are 2), for better coverege .Or forget travels outside bern oberland and buy 8 days bern oberland pass.Am I right?

ehsanemrani,
"it is better for me to buy a 8 days swiss flexi pass saviour( we are 2), for better coverege .Or forget travels outside bern oberland and buy 8 days bern oberland pass.Am I right?" - YES. The Berner Oberland Pass gets you some extra mountain railways and cablecars which are not covered by the Swiss Pass.

I understood you would be buying the pass in person in Switzerland, due to online credit card restrictions, so you should plan to re-confirm the discount offer there at the station.

[Edited] Part of your Flex pass confusion may be due to the fact that the rules changed in January, 2015. Chris and Sam have both mentioned the 60-CHF "Half-Fare Combi" add-on, which allows you to get discounts in between the 3 counted travel days on the Flex pass you are considering. You must buy this at the train station, otherwise, you won't get any discounts in between the counted days of a Flex pass.

Rather than try to do all the math to make detailed comparisons for all the side trips you mentioned in your last thread, you may still decide a bigger pass is more convenient, for 8 consecutive days.

Thanks.I think it's better to buy 8 days flexi saver ( we are 2) ( in saver i pay less than 2 swisspass?).Or forgot first and last days ( Basel to interlaken and Bern to Paris), and buy 8 days bern oberland pass( where? in Basel? ).I dont know it has an option for two people travel together ( saver ) or not.I dont want to use math ,don't take it hard, gimme an advice with the minimum of math.
I didn't get reconfirm discount offer at station, you mean they have some discounts depends on day?

SBB replied to confirm that the 60 CHF Combo is still for sale in stations there, to use together with a Swiss Travel Pass Flex, although it's not online.

• There is no saver discount this year; each adult pays the same price that you have been quoted.
• I and others have recommended that you buy the direct TGV train ticket from Paris to Interlaken on the train that departs Paris at 18:23. Is it on your calendar for August 25?
• Have you made a plan for the return to Paris on Sept. 4, based on the previous thread/discussion? The options discussed for departing from Geneve or Lausanne did not need to use a Swiss pass on that date.
• You will only be in Switzerland for basically 8 consecutive days and only need a pass for 8 consecutive days, probably to use 8/26-9/4. You don't need a Flex pass for $50 more. You can choose the Swiss Travel Pass for 363 CHF or the Berner Oberland Pass for 340 CHF, which gives more coverage in that area, but not covering the portion of your later trip from Bern to Lausanne or Geneve (50 CHF).

Forget this. But if you have any more questions about Swiss Passes, you should ask them in Switzerland.

Thank you Laura.Yes we will arrive aug 25th , depart sep 4th.we forget Lausanne for next , like lucerne . Our plan is 8 nights in interlaken and 2 nights in bern,. Many people talk about saverpass
and I am disappointed that there is no saver pass.With your suggestion We must buy our pass in interlaken at first day.
I read this :
The Swiss Half Fare Card Combi entitles the owner to the purchase of an unlimited number of tickets at the Swiss Half Fare Card terms, between the first and last day of the associated valid Swiss Travel Pass Flex/Swiss Transfer Ticket (max. 1 month) only.
So I thought I can order 3 days flexi with half fair card combi by 299 CHF each.instead of 340 CHF bernese oberland each for 8 consecutive days. Difference will be 82 CHF, but I think this way ( 3days with half fair combi)cover us less than bernese oberland pass.worth or not I dont know.
In bernese oberland pass I found 2 prices ,340 and 255 reduction swiss travel system.what is it.

We will be 11 days in Switzerland, from the day we enter border (aug 25) till day we leave.I pay a big amount ( bernese oberland or swiss pass...?) Just to cover 8 days, and forget 3 days. NO other way?day we arrive and depart have some distance in france, i know .and we must forget a day in bern...we plan to see 2 museum.
And, at last, first or second class, I am handicapped , is it a good benefit for me, seat reservation or anything like that

Seat reservations are not used in Switzerland except on some special tourist railways.

For normal travel seating is first come, first pick.

If your disability includes stairs you should know that many trains in Switzerland are double decker.
