Squash in Switzerland is quite well organised which might have something to do with the president of Swiss Squash being English - Essex boy actually...
Around Zürich there are several clubs including Airgate and Vitis.
Airgate has no real interest in squash they simply inherited the courts and are therefore quite expensive.
Vitis is a specialist racket centre with several courts including a two wall glass court. They also have some dodgy flooring so watch out which courts you get if you like your knees.
Other clubs include Grasshoppers. They are out Zollikon way near Hirslanden stuck off the beaten track a bit and you will need a car or be fit to get there. They have a great English pro Mark Woodliffe and an English atmosphere.
And Swissair in Bassersdorf which is fine but a bit run down and a bit cliquey.
There is also one near Bülach but I was never there so no comment.
And then slightly further afield:
Frick great place this best courts in Switzerland and very friendly with a website of their own -
www.squashfricktal.ch - this is a pay for the year and use it as much as you want, when you want place
Langnau which is a la Vitis just a bit(lot) friendlier.
Wintherthur which is also quite friendly but dark and imposing -courts are fine though.
Any questions please ask and if you are any good lets organize a game - in Frick of course cost on me. If anyone wants to organize a (semi-)regular Sunday morning game let me know. I can provide the courts etc at a very good rate.
Mark am I being too commercial here!
