Hi, and welcome to MySwissAlps!
>> I will be having a Swiss Travel Pass. I'm trying to get a total price on the following itinierary: Grindenwald-Mannlichen by Gondola, hike to Kleine Scheidegg, Train to Jungfraujoch, then back down to Lauterbrunnen. I've checked the Mannlichen website and it seems they have a price quote for 94 CHF with SwissPass, but I'm not certain. I'm wondering if anyone has information that can help?
That discount price doesn't seem quite right, as it is applying a 50% discount for the whole trip, which is not correct for people using the Swiss Travel Pass. (It is also for a return to Grindelwald Grund, rather than going down to Lauterbrunnen.)
Note that the gondola to Männlichen from the Grindelwald side goes from Grindelwald Grund, not Grindelwald. Unless you are walking to Grindelwald Grund, you will need to account for the fare from Grindelwald to Grindelwald Grund as well. It's not much.
Discounts with Swiss Travel Pass:
Grindelwald to Grindelwald Grund - train - 25%
Grindelwald Grund to Männlichen - gondola - 50%
Kleine Scheidegg to Jungfraujoch - train - 25%
Jungfraujoch to Wengen - train - 25%
Wengen to Lauterbrunnen - train - free
