Swiss half-fare or swiss pass?

Hi emeline, and welcome! Since you'll be traveling in May, you can use the current 2 for 1 offer on the 4 day Swiss Saver Pass. If you order a 4 day Swiss Saver Passe twice for the entire group, you can thus cover all 7 days of your stay. This offer is by far the most economical solution in your case and it will save you lots of money. More information on the Swiss Saver Pass and ordering options, including the 2 for 1 offer, can be found at the Swiss Pass page.

Does that answer your question?

Hello emeline! Both routes are entirely covered by your Swiss Saver Pass (please refer to the validity map we link to from the Swiss Pass page). Details on the trips can be found in the timetable. The shortest route is the first one via Grütschalp, and that's the one the timetable will display. If you want to see details on the route via Stechelberg, you have to fill out 'Stechelberg' as a via-station. Does that help you out?
