Hi,
I know that feeling, but the great news is that a lot of people have hard time to que socialized in CH and therefore form their own international groups.....I have a group on my own from the Hiking and Outdoor Meetup Group. We have over 200 members, mostly young people signed up that are interested to get to know each other and by the side Switzerland as well through their own common hobby: Hiking.
The Meetup Group is from the internet platform http://hiking.meetup.com/287/. If your interested, check it out and participate in one of our events. No commitment whatsoever.

Cheers,
Sven
