Confused Australian ( don't laugh)

Hello Sparkle! Of course we won't laugh. Picking the right pass for your Swiss holidays can be quite confusing indeed! If your trips from Mürren are mainly within the Jungfrau Region (such as Schilthorn, Kleine Scheidegg, Jungfraujoch, Männlichen, and so on), a Swiss Half Fare Card will most probably be cheaper than one of the other Swiss rail passes. The Swiss Card and Swiss Transfer Ticket aren't economical, as your inbound and outbound journeys are relatively short and inexpensive. Both the Swiss Pass and the Swiss Flexi Pass would prove to be quite expensive for your rather short stay, which seems to include short regional trips from Mürren. Moreover, the free travelling allowed with a Swiss (Flexi) Pass doesn't apply to mountain transportation, so you wouldn't really profit from such a pass when visiting peaks from Mürren. Only exact calculations would provide a definite answer, but if you don't manage to figure it out, all you can do is make a reasonable guess.

I hope this helps you getting less confused...

Hi Sparkle. With a Swiss Half Fare Card, you have to purchase 50% discounted tickets for each trip. These can be bought right before boarding, from ticketing machines or ticket offices at the railway station. You can pay either in cash or, in some cases, by credit card. The Swiss Half Fare Card can be purchased online, but in your case (Swiss Half Fare Cards for Australian travellers) this is currently more expensive due to shipping rates. It can be bought at Swiss railway stations as well.
