If I go from Grindelwald to Jungfraujoch (one way), with Swiss Travel Pass (I am international guest), then I should get a 25% discount, right?
Then when I down the hill from Jungfraujoch to Lauterbrunnen , with Swiss Travel Pass, should I buy a ticket also with a 25% discount? Because I cannot find such an option item in the ticket box on your website.
