Switzerland is stunningly beautiful. However, it is also incredibly expensive. There is a lot to do whether you visit a city or the countryside.
Walk around Zurich - it is a really unique town with amazing architecture and lots of churches as well as cute shops and restaurants
Lake Zurich - I walked along the lake for a bit and took a train along it as well. It is beautiful and right on the edge of town.
Zermatt - while I didn't visit this trip, a visit to Zermatt and the Matterhorn should be at the top of your list. It is such a cool thing to go up in a glacier and the town is very cute.
The official currency is the Swiss franc, but I had no problem paying by credit card as well.
I walked throughout my time in Switzerland. I took a train from Zurich HB to Zürich Flughafen.
I took a train from Luxembourg to Mulhouse Ville and from Mulhouse Ville to Zurich HB. I took a train from Zurich HB to Sargans and a bus from Sargans, Bahnhof to Vaduz, Post. I took a bus back from Vaduz, Post to Sargans, Banhof and a train from Sargans to Zurich HB. I flew Swiss Airlines from Zürich (ZRH) to Nice (NCE).
Switzerland has great food but it can be really expensive. 5CHF for a bottle of water was unfortunately common. I recommend that you stock up on cheaper water at a local grocery store. It is difficult to find inexpensive Fondue so I would only splurge if there are at least two people eating. A good substitute for one person is Raclette. I found relatively inexpensive Raclette at Raclette Factory in Zurich. I also had a spezial servelat sausage that was really tasty
PLUGS / ADAPTERS
Switzerland uses European plug types C and J.
None for U.S. citizens.
I felt very safe throughout my time in Switzerland.
SHOULD YOU VISIT?
Yes! Switzerland is a really expensive country so just be conscious of that. Travel is not too expensive, but food definitely is. It is possible to do Switzerland on a budget but it takes planning. It is an amazing country either way. Zermatt is a really cool town and I loved spending some time in Zurich this trip. I hope to go back in the future and visit Geneva.
