Hello! I will be staying with my family of 4 in Interlaken this July. We will all have an Interrail pass (1st). I’m sure I read before about passes being used to get boat trips Lake Thun and Interlaken. Does anyone know if this is the case and if you need to book in advance or how you go about this? Any recommendations much appreciated!!

The Ferry on lake Thun and lake Brienz is fully included. You just add it like all the other trains and activate the journey.

@Scottish Sarah 

It is not necessary to book in advance. If you have a flexi pass, you will need a travel day.1st class is on the upper desk, but seats are not always better as in 2nd class.

@Scottish Sarah If it fits into your Schedule i recommend taking one of the historic ferrys.

I think they run 2 times a day in summer.

Thank you for those details. I have the 10 days in 2 months pass, so I would have to use a travel day? 

Also, any recommendations of which lake might be more enjoyable - Thun or Brienz?

Where do they depart from?

Thanks in advance 👍🏽

Yes you need an active travel day to take the ferries on lake Thun and Brienz. 

The ferries start directly at the train stations Interlaken Ost and West (depending on which lake you want to do)

They also stop close to the train stations in Brienz and Thun.

No need. You can not even reserve in advance. You just add it like any reservation free train to your pass and are good to go.

If you are in that are and have an active travel day, you can also take the cable car(Lauterbrunnen ->Grütschalp) + train to Mürren (I just noticed that it is closed from 13. April until 10. July 2026) It is also included like normal trains. Starting from Interlake Ost it takes arround 45min to get to Mürren.

Thank you. Is Lauterbrunnen in Interlaken, or we have to catch a train there? Is the cable car like the ferry - you have to use a travel day? Could we do both in 1 day using the same travel day? (I only have 1 travel day free! 😄)

Yes its like the ferry, and of course you can do both on the same day. The 45min were from Interlaken. Its a short train to Lauterbrunnen, then the cable car and then another short train ride.

@Scottish Sarah I would choose Brienz. You could also make one way by boat (80 minutes) and one way by train (20 minutes). You would have more time to visit Lauterbrunnen and Mürren with the same travel day.
