This is the complete list of the Swiss clubs. However, be aware that in
Switzerland, gliding is done mostly on a club basis. Which often means
weekend only operation and limited access to double seaters and instructors.

If you're looking for a granted weekdays operation and want to get an
introduction to the art of mountain gliding, try
http://www.schaenissoaring.ch/. This is one of the few full time
operations in Switzerland and very well situated for gliding in the
Alps. The convenience comes at a price, though.
