How do you go from Bern to Lauterbrunnen by coach?

Answer 1

The timetable is basically exactly the same on all days of every week and throughout summer and winter. You first need to catch the train from Berne to Interlaken Ost (do not get off at Interlaken West which you stop at before Interlaken Ost). Trains on this line run about every half hour from early morning to late at night and journey takes 2 hours 3 minutes via Thun and Spiez.

On arrival at Interlaken Ost trains from there leave every half hour for Lauterbrunnen via Wilderswll and Zwellutschinen, and this journey takes 22 minutes.

As an example say you get the train departing from Berneat 0906 that will arrive at Interlaken Ost at 1003. You then can catch the next train from Interlaken Ost which departs at 1020 and you arrive at Lauterbrunnen at 1040.

Answer 2

I don't think there is a coach.

It is much easier to go by train, Bern - Interlaken and Interlaken - Lauterbrünnen. One train per hour.
