Welcome Stathis!!
Yes, you will find many other skiers here in Geneva. You can join ski groups, you can look in Things-To-Do and see if anyone is going skiing and has an extra spot in their car, etc. Lots of opportunity.
Since you have found glocals, it is SUPER EASY to find/meet people. Check out the groups above: join the ones that interest you and then join their events. Also, people post activities on Things-To-Do, so if you want to go see the new Thor movie, you can join a group who is going. Or, you can post an activity yourself and people will join you.
For me, I post weekly activities such as Mr. Pickwick Pub Quiz (Mondays), NFL Football (Sundays), and Tuesday Volleyball. I also join the Sunday Games Group sometimes.
There are also language exchange activities, movie nights, bowling, after-work drinks, and more.
You're sure to find something or someone...
