Give me your advise
 

Will be in Switzerland area for 4 weeks. Gone to Italy and France already. What would you recommend doing during this time.?

Climb every mountain, ford every stream, follow every rainbow, etc., etc.

Why did you choose Switzerland?

lol, fra.

Take yodeling and schwinger"ing" lessons.

Or is that schwingening ?

logos - Schwingening is correct!!

4 weeks is a long time & Switzerland is a small country. I would simply purchase some kind of Swiss train pass, get some maps, and a guidebook.
