Did Switzerland and France last summer, would highly recommend Bernese Oberland area if you are a nature lover. Be a good amount of tourists but if you do any moderate walk up the mountain it thins out pretty quickly. We planned to do the tour du mont blanc but plans changed so we did our bases out of Chamonix, Zermatt and Grindelwald. Would love to go back and check out Italy next year and Austria.
Did not expect open pits of bears in Bern... that was a surprise. I guess a quick Google search would have been helpful.
