Come play Knockerball Fridays through Mondays, from noon - 8:30pm all summer long at Seminary Park in downtown Lake Geneva. It's a physically fun, energetic activity that will have you smiling and laughing from the moment you put one of our big inflatable balls on to the time you take it off. Enjoy the thrill of hitting others or just partake in rolling somersaults and back flips if that's more your thing. Whatever you do you're sure to have fun and make memories that will last a lifetime! $5 per person.
