Hi drpsp and welcome to MySwissAlps!
None of the Swiss rail passes will cover train trips outside of Switzerland. You will need to buy a ticket from Paris to the Swiss border town (this will depend on your first destination in Switzerland) and then another ticket from a Swiss border town at the end of your trip to Austria.
Deciding on if buying a rail pass for Switzerland – like the Swiss Travel Pass, is worth it, depends on how much train, boat, bus and gondola trips you are planning on making while here (and the areas of the country you are visiting).
If you need help planning your trip in Switzerland look at our pages on:
Once you know your rough itinerary we can give you feedback on what the best rail pass might be.
Also, be sure to read through our page on How to choose the best rail pass.
