Okay this "sport" has completely taken the US by storm.
It's combination of badminton, pingpong and tennis... It is beyond fun to play and anyone can pick it up (especially ping pong players, badminton players, squash and tennis players). But actually, most can pick up this sport. As a reference, I come from a pretty athletic family and my sister never played any sport growing up, but she took up Pickleball during COVID and she is good! Shocking but true
There is a venue in Zurich (Kusnacht Goldbach) and this such a fun sport. Here is the link to the website:

They play Wednesday afternoons from 2- 4:30 pm as well as Tuesday evenings.
If interested, click on the website and enter your contact details. The administrator will send a doodle link. It is only CHF 5.05 each time one plays.
I highly recommend as it is so much fun and would suit almost anyone. Great exercise, lots of fun and good practice for those like me trying to learn Swiss German. (We have a few English speakers but the majority are Swiss

)
Give it a try if you can
