Cerka-Firka Playground hides on top of Gellért Hill. We can easily approach it from Móricz Zsigmond Square with bus number 27. Not only children, but adults too can feel tiny among the huge, colorful pencils, which mostly function as a jungle gym. A few more of our favorite elements are the giant pencil sharpener, which is actually a treadwheel, and the in-ground trampoline. There are also roundabout, swings, and a Useful Waste Path (Hasznos Hulladék út). While walking through this, children can learn how composting works, for example. Once we are around this playground, it is worth dropping by the Citadel, as well.
