Hello everyone,
If I have a Swiss Travel Pass Flex, do I need to buy anything more if I want to go from Interlaken to Grindelwald? Can I just go to the Interlaken Ost station and take the train to Grindelwald? And then to go to Jungfraujoch from Grindelwald that same day, I do need to buy a separate ticket, yes, for that part of the trip. Or can I still just use my Swiss Travel pass to get to Jungfraujoch without buying an extra ticket.
