There's an open golf course not far away from Baden (i.e. you don't have to be a member - and golf memberships are fairly expensive in Switzerland). It's owned by one of Switzerland's largest supermarket chains.
Here's the link (German only I am afraid):

And you need to pass a test in order to get access to the greens (Platzreife).
Having played golf (very badly) in Japan where anyone can play (however bad you are), it was disappointing to find this restriction, although I can understand it given the limited number of courses here.
What is my handicap? My game.....
