The Planetenweg, or Planet Trail, is a hiking route that functions as a physical scale model of our solar system. Stretching between the Uetliberg and Felsenegg, the path uses a ratio of one to one billion, where each meter you cover on the ground represents one million kilometers in space. You can identify the stations by the boulders placed along the trail, each bearing a model of a planet and a plaque with technical information.
