Binoculars recommended for Switzerland?

I've never taken binoculars to Switzerland. Those mountains are pretty big. :-)

Also, i have a decent zoom on my iphone.

I often wish I had them but I am not willing to schlep that weight.

I was on the Switzerland tour last year. The only time I would have wanted binoculars was when we were milling around after an activity and some cows were coming down a neighboring mountain. We could hear them, but they were tiny. The rest of the time binoculars would have been a waste of space. I got a decent view through the zoom on my camera.

Thanks for the replies! I will not take them.
