We will be in Switzerland for 4 nights at the end of this month. (I know that's the worst time to go. We had planned it for September but have to go now or never.) We are planning on staying the entire time in the Interlaken area, but I wonder if there's enough to do there this time of year, or if we should spend two nights there and two nights somewhere else. (We don't want to stay anywhere for less than two nights.)
I figure we could spend a day exploring the Lauterbrunnen valley, and we will go visit the Aare Gorge. I had hoped to go to Kandersteg and Oeschinensee, Murren, Wengen, etc, but there will probably be too much snow and mud. Maybe Grindelwald will be ok though. We aren't doing the Jungfraujoch, and depending on weather it might not be worth it to do any of the lifts. We could do a day trip to Zermatt, although it's a long one. I didn't want to plan a trip specifically around Zermatt as if the weather's bad there's no point, but it would be nice to have that option. There are of course the lakes, and Bern and Luzern, although we're not so much into cities.
Is it worth staying there that long, or should we spend a couple days somewhere else like St. Moritz or Appenzell? And we are heading to Stuttgart after so don't really want to go too far southwest. Another option is to go up to Colmar and the Black Forest instead, but I hate to short change myself on Switzerland.
Thanks. A little discouraged; a lot depends on weather which is unpredictable.
