Kugelbahn (rolling ball tracks) in Luxembourg

Locations on Google maps: 📍 Kugelbahn Berdorf 📍 Kugelbahn Mullerthal

The photos above are from the second location, but the general concept is the same at both places: for €2, a child gets a wooden ball from a vending machine and then sends it rolling through a series of tracks with slopes, ramps, bells, spirals, mazes and all sorts of other obstacles.

Then a child collects the ball at the end, starts it again, and repeats the whole thing until they get bored, which takes a surprisingly long time.

And note that both bridges over the river are also part of the ball tracks 🔥💪
