At the mountain station of the Eifelpark, the destination for families with children in Rhineland-Palatinate, you can find the softball shooting range right next to the summer toboggan run exit.
With a total of six air cannons, you can duel with each other using foam balls. Adults have apparently been seen here, too. Great fun for the whole family!
Location: On the mountain station at the exit of the summer toboggan run, diagonally opposite the puppet theatre.
