Week end clost to Zurich

Since when I moved to Zurich, I had no any summer sightseeing.

I would like to go on a charming place in the mountain with the simple requirements :-) :

- By car is more convenient for me, but not more than 1.5 hrs
- I do have a 2 years baby
- Don't want to get freeze :-)
- I would like to have the tipical Swiss scenario, caws, mountain small lakes

Could you kindly advice?

Thank you!
