GraviTrax Junior: Desert Starter Set introduces kids ages 3+ to marble run building with chunky wooden tracks, desert themed décor, and animal friends. This beginner friendly set has all you need to build simple runs and create a warm, sandy play world.
GraviTrax Junior: Desert Starter Set is a first step into marble runs for younger builders. The box includes large, easy to handle track pieces plus desert themed decorations and figures, so kids can build a basic course and then turn it into their own sunny landscape. As they roll marbles through curves and slopes, they explore cause and effect, spatial thinking, and gentle storytelling in one activity, with room to grow later by adding other GraviTrax Junior sets.
