Yes! I was there in September, but I never was in Zermatt. I was all over most of the rest of the Swiss German part of the country, however. The country is easily the most beautiful place I’ve ever been. For example, my Facebook cover photo is an iPhone image I shot while hiking near Jungfrau.
The only tip: Be. On. Time. If you’re even 30 seconds late to anything, Swiss people call you out on it.
