GraviTrax Junior Starter Set L Jungle – Sustainable Marble Run

Introduce young builders to construction play with Ravensburger’s GraviTrax Junior Starter Set L Jungle. Specifically designed for children ages 3–7, this open-ended marble run system encourages imagination, discovery and hands-on learning.

The set includes 100 easy-to-handle components, featuring six hexagonal baseplates, 34 stackable height tiles, straight tracks, ramps and curves, plus interactive elements like a hammer and seesaw. Three marbles bring motion to the build, while themed decorations—jungle animals, plants and scenery—add immersive storytelling appeal.

With parts made from sustainable wood-bioplastic and oversized for toddler-friendly use, the system is easy to build without adult assistance. Illustrated instructions and modular templates guide early STEM learning through trial and creativity. Children explore cause and effect, spatial layouts and problem-solving in every build.
