Travel pass in swiss and france ?

Question

Hello guys !!! i will be going to switzerland during winter for around 10 days. So i got some question to ask about transportation.
1) i will be going to paris for only a day is it worth it to buy the France-Switzerland pass or should i just buy the swiss pass only ?
2) Does the France-Switzerland pass allow me to travel free in zurich? And does it have discount when i taking mountain top ride such as Jungfraujoch ?
3) And how much is the round trip ticket through and fro paris from zurich ?
4) I will be visting Arc de Triomphe, Eiffel Tower anything to visit as i only have a day over at paris ?

THANKS A LOT !!!

Answer 1

If you're under 26, you can get a France/Switz youth pass for $258, but 26+ it's $368.
A round trip from Paris to Zurich is about $334. (US$)
The Swiss pass wouldn't include all the private railways and as for city trams, you might be able to pull it off. Read the details about the paritcular pass before you buy it.

has good info
If you get a France/Swiss pass, make sure your train doesn't pass through Germany, as that wouldn't be included.
One other thing to consider is a France pass, 3 days/2nd class for $237, Then buy separate tickets through Switzerland. But don't expect bargains!
You could possibly fly more cheaply.

Answer 2

Reconsider going to Paris for only one day.
There is a lot to see in Paris and you will not see much in a day, and it is quite a distance.

If you take the high speed train it takes 4 hour from the Swiss/French border to Paris, which will not be included in a rail pass. (Or at an extra fee.)

Search your preferred trains on these sites:

I can not judge whether a railpass will be worth it for Switzerland, specially as only part of the mountain trains are included. (I think that the JungfrauJoch was included up to the one but last station, while it is the last station you want to see. Been a long time, I do not know how the situation is now.)
I think you would get a discount, or free travel till the last station included on the pass, (but again I am not sure.)
I do not expect you to make enough use of the French railways to make a pass useful, but check the prices against a pass.
