Which rail pass?

Hi J! Which option is most economical, depends on your exact travel plans. If the trips you mention below are the only ones you'll be making, the calculation with 2nd class prices would look like this:

Geneva-Zurich-Geneva: CHF 166.00
Zurich-Jungfraujoch-Zurich: CHF 307.80
Zurich-Schaffhausen-Zurich: CHF 36.40
Total: CHF 510.20

A 4 day Swiss Saver Pass costs CHF 221.00 and allows free travelling in regular trains, boats and buses. The trip to the Jungfraujoch is discounted by 25% from Wengen/Grindelwald and adds another CHF 111.75, making a total of CHF 332.75 and saving you CHF 177.45. The only disadvantage of this pass is that it covers only 4 out of the 5 to 6 days you'll be travelling. This is no problem if either the first or last day(s) of your stay will be spent in Geneva and if not that much travelling is involved these days. If you'd want to cover all days, an 8 day Swiss Saver Pass of CHF 320.00 would still save you quite some money, as the total including the Jungfraujoch trip would be CHF 413.75.

A Swiss Half Fare Card costs CHF 99.00 and allows a 50% discount on all trips, making a total of CHF 354.10. A disadvantage of this pass is that it requires you to purchase discounted tickets for each trip and therefore doesn't offer the same ease of use as the Swiss Saver Pass.

I hope this helps you decide! Kind regards,
