Before I do some in depth research, I was just looking for suggestions on where to spend those 5-6 nights. I'd like to spend at least one night in Lucerne, but my wife and I are more interested in seeing the mountains, and are looking for some easily accessible places with beautiful views and some cool things to do.
I've heard about places like Interlaken (mixed reviews), Murren, Wengen, Grindelwald, Lauterbrunnen Falls, and St. Beatus Caves. I would really appreciate any advice on which are the better options and how to maximize my 5-6 nights. Thanks for the help.
