Hi Regina,
You have a few options. Go along to the swiss alpine club on a Friday night to see what courses they are running. I know there will be an Alpine climbing course coming up - I did this last year and it was great. There is also an indoor climbing gym in St Legier - it seems quite good and you may be able to find someone who needs a climbing partner or meet a group of climbers there.
Another option is to come along to the Lausanne social nights and meet a few of the guys - I think a few of them went climbing last weekend, thats if Paul got over his hangover from last thursday

Although you may get talked into cycling trips if Chris gets a hold of you
Cheers
Kathy
