Thread: Travel in Switzerland

Hi to "Fly without reservation" and everyone else on the forum,
This is my first real post and am hoping for lots of help on planning. (My first post was very "terse" because I had been having GREAT difficulty getting any message to post and I was tired of typing the same stuff over and over... )
SO - here's my story. My husband (retired AA) and I will be traveling DFW-ZRH the first week of July and plan to stay about 7 days. All I know is I want to "ride trains and see mountains." Other than that, we don't know much about where to go or what to do. We are reasonably healthy for retirees, but not interested in snow sports, extreme or strenuous hikes, or nightlife - more into historical sites, shopping, etc. On flat land we could probably walk people half our age right into the ground! I have read lots about Zermatt and the Glacier Express, but I am open to any and all "don't miss" sightseeing. I have been thinking about going from Zurich to St. Moritz by train, then to Zermatt, then to Montreux, and end in Geneva. What do you recommend?
Thanks in advance.
