Mystic What to do while booking tickets from Grindelwald to Jungfrau?
You can book tickets on this website or at the ticket office in Grindelwald. It is not recommended to buy them in advance, wait to know if the weather is good, it is very expensive to see only fog, rain or snow.

Mystic while booking from Zurich to Munich through SBB app
You need a ticket only from St. Margrethen SG to Munich. I suggest to make two transactions:
– Make only a seat reservation from Zurich to Munich on oebb.at or in the ÖBB app.
– Buy a ticket from St.Margrethen to Munich on the same ÖBB site or compare the prices and conditions with Bahn.de or the DB Navigator app. You may have other options for the Saver or Supersaver Tickets.
