German, French, English and Italian also.
SWITZERLAND is near France, Italy and Germany. For this reason there are a lot of languages.... Where do u want to go??bye bye

i was just there for spring break and the main language there is swiss-german. it's a very hard language to learn, although i found that everyone pretty much spoke english also.
goodluck

It really depends on where in Switzerland you are travelling.

I live in Geneva and people speak French (although there is a good grasp of English for touristy things). Once you get into the Swiss German areas, they speak more English then French (and of course the predominant language is German).

In Berne we found people spoke both French and German. We notice that in places slightly off the beaten track which are Swiss German that they speak no French but some English). Of course, Ticino they speak Italian ...

I've been to Switzerland many times and in larger cities or where many tourists visit almost everyone speaks English. I admire that you want to fit in and speak with the locals, so the first choice of language would be German. It's the most spoken language in the country, followed by French. Speak the language the canton has as a first language, for example, Zurich is German, Geneva is French, and if you go to Berner Oberland it's a bi-lingual canton. German and French are spoken the same amount.
