Swiss Pass/Mont-Blanc expr. repl. bus to Chamonix

The Swiss Flexi Pass is listed as valid on the Mont-Blanc Express train from Martigny to Chamonix (France).

But the SBB site says the train isn't running and lists a bus to Chamonix as alternative (as shown below).
1) Would the Swiss Pass be valid on this bus to Chamonix too?
2) Is this bus journey worth it? I heard the Mont-Blanc train ride is very scenic. Would the bus ride also be that scenic?

Hi nytraveler! Yes, the Swiss Flexi Pass should offer the same benefits for the replacing bus. I don't know the exact bus route, but since it stops at the railway stations along the train line between Martigny and Chamonix, it covers roughly the same route and should be scenic too.

Have a great trip!

Thanks a lot.
I just returned from my trip.
The pass was valid and the route was very scenic!

You're welcome nytraveler. Good to hear that you liked that route!

Hi, Nytraveler.
Thanks for updating your question with your experience.
I once again seek your advise. My wife & me will visit swiss in first week of May 2012. We have already purchased Swiss Flexi Pass 2 for1. Please confirm that I can travel from Montreux to Mont- Blanc via Martigny. Do I need reservation or separate ticket, in addition to flexi pass as I will be moving out of Swiss.

Hello jogijsr,

Do you mind if I try to answer your question? First I would like to draw your attention to this topic (about busses replacing trains on the leg Vallorcine - Chamonix-Mont Blanc).

You will travel for free with your Swiss Flexi Pass as long as you take care that you use your last free day for this journey (last free day, as you will be leaving Switzerland). Reservations or separate tickets are not necessary.

Hope this helps.

Wishing you a lovely stay!
