Travel from zurich to interlaken with swiss pass

Hi kumars. The type of train doesn't matter, you can enter them all with your Swiss Pass. (Only special panoramic trains would require additional seat reservations, but that's not the case here.) Platform numbers can often be found in the timetable. If not, don't worry. At the railway station many digital information boards will provide direct guidance as to where your train leaves. 6 minutes for a change should be enough, unless you're with a large group or need to carry a whole lot of luggage. If you miss out on your train it's no problem though, you can simply wait for the next one.

Hi kumars. No problem, there are lockers at the railway station of Spiez. You can plan your boat trip to Beatenbucht and the rest of the trip through the BLS website and the timetable I provided.
