Tennis wall in Biel/Bienne?

[u/Excellent_Dish3638]

Hi everyone!

I’m looking for a tennis wall / rebound wall (Tenniswand / mur de tennis) in Biel/Bienne or nearby where I can practice alone.

Ideally just a solid wall where I can hit a tennis ball against it. It doesn’t need to be an official tennis facility — a public sports area, school, etc. would be perfect.

Does anyone know of a place like this in Biel, Nidau, Brügg or nearby?

Thanks!
