There are two of us, who are staying in Grindelwald for 3 nights in early July. We plan to arrive at Grindelwald at the first night from Zurich. The second day is to travel around the Jungfrau region, provided that the weather is fine. (Grindelwald > Kl. Scheidegg > Jungfraujoch > Kl. Scheidegg > Wengen > Lauterbrunnen > Interlaken > Grindelwald) Is this travelling order correct by trains? Would time be too limited to walk around all these cities (Wengen, Lauterbrunnen and Interlaken) with just 1 day? We are buying Swiss Passes and I’m quite confused by its coverage. Which parts of the above journey needs tickets? Should the tickets be bought one night before travel? If so, where and when should we buy in Grindelwald? We wanna know this in order to figure out the suitable time of our train from Zurich to Grindelwald.
The third day is to visit Lake Bachalpsee by cable car to First. (Again is purchase of ticket required one night before?) We walk to Faulhorn then and have lunch in that hotel (expensive or not?), followed by going to Bussalp and getting post bus back to Grindelwald. Is this plan feasible and is hiking in this way suitable for those who are healthy but lack experience?
Sorry for sooooo many questions but I desperately want to eliminate my doubts and have a nice trip there. Hope to see your answers and your help would be greatly appreciated!!!
