We will have two days in Bernese Oberland area around October 22, possibly as two day trips from Lucerne, possibly with one overnight in between two days. Of the below, what do you think can be accomplished realistically at a relaxed pace? (I may have things mixed up so please feel free to correct me or make better suggestions to see that beautiful area as much as possible with the limited time.) TIA.
1) Lauterbrunnen to Murren via Grütschalp cable car then hike to Gimmelwald. Can eat at The Pension. Then back to Lauterbrunnen via gondola.
2) Panorama Trail-Lauterbrunnen to Wengen cable car to Mannlichen, walk to Kleine Scheidegg and then train back to Lauterbrunnen.
3) explore Lauterbrunnen and see Staubbachfall andTrummelbachfalls
(Can 1-3 be done in one day?)
4) Interlaken Ost to Harder Kulm via funicular. (Is this worth our time?)
5) Grindelwald First gondola/First cliff walk
6) Brienz Rothorn Bahn train from Lake Brienz up to summit
7) Thun from Lauterbrunnen.
8) Lake Brienz- take boat across the lake, stop at Iseltwald and hike to Giessbach Falls.
