Swiss pass or Half-fare card?

Hi fussytassy. These are relatively short journeys, so if the trips you mention here are the only ones you plan to make, the Swiss Half Fare Card would be an economical deal. You do have to buy 50% discounted tickets for each trip though; these don't have to be pre-booked, you can just arrange for them at the manned desks or ticketing machines at the railway stations.

If you'll be doing more side trips than you listed here, and prefer not having to buy additional tickets for each trip, a 4 day Swiss Saver Pass for the adults and 4 day Swiss Youth Passes for the youths would more convenient. This would also grant free boat trips over lakes of Thun, Brienz, Lucerne and Zurich, but I don't know whether you've planned such a thing. Please find details, including purchase options and links to validity network maps, at the Swiss Half Fare Card and Swiss Pass pages. I hope this helps you decide!
