Hi, well when I went to Switzerland… you should definitely check out the Mt. Jungfroujoch. It is known as the Top of Europe; it’s the tallest mountain in Europe. When I went up there, it was absolutely gorgeous, it’s …fantastic, I don’t know what word to use it’s just worth checking out. However, if you are okay with it, there is a fee which I’m not sure how much it was exactly, but it was a little over 100(in swiss francs) with a discount. You purchase your ticket for “The Goodmorning Train” that leaves at 6am to the top. It takes 2 hours to get up there. When you get up there, you will see panoramic views, an ice cave, a sky resort, and little towns. If you love to snowboard or ski (like me) definitely snowboard here.
When are you going? When I went, I went during January and they closed the very top for skiing/snowboarding, but then they reopen it in summer.

There’s another mountain that’s near there, it’s not the highest, but there’s a rotating 360 degrees restaurant where one of James Bond movies were film. I haven’t visited there, but I heard that it’s even a better view.

After you check those places, there’s really only one main street with all the shops and restaurants. Have some great fondue.

Other than that, enjoy visiting Interlaken!
