Hi Rawabia7, thanks for your enquiry. It is possible for people with disabilities to use our funicular. If the person is unable to walk the few steps into the first cabin, there is a separate entrance, where one can drive to (first road to the left from the Harder station onwards). You must however inform the staff beforehand as well as get your tickets. Let me know if you need more information. Regards, Teiger

Yes, you can

You don´t need a Swiss Pass.

You can either buy it online(sbb.ch) or at any kiosk at the train stations/airports. I would recommend going to a SBB outlet and getting their suggestions depending on your itinerary.

The train leaves early in the morning if you want to spend reasonable time in the top of Jungfrau. Recommend buying tickets at least the day before, just checking the weather forecast. For Harder Kulm, no need to buy tickets in advance as it is close to Interlaken, you can get the tickets as & when you decide to go. Easy. Jungfrau is 3 trains to get there & buying tickets ahead of time essential if you want to guarantee going on a certain day. This is a very popular trip. Still very worth doing, a real highlight.

sorry - I didn't understand your question completely - but if you are asking whether you need to buy separate tickets for return? well - you can buy to and fro tickets at the base when you board the furnicular to interlaken to harder klum. You also have the option to buy a one way ticket - you can either hike up or down or both ways - it takes about 1 : 45 mins usually for a hike up!
