Toy marble run Ravensburger GraviTrax Junior Extension Desert 3 to 7 years

The Ravensburger GraviTrax Junior Extension Desert 3 to 7 years adds desert-themed components to the GraviTrax Junior system, expanding creative building and marble-run possibilities for young children. Designed for ages 3–7, the extension brings new textures and shapes that integrate with the base GraviTrax Junior set to create varied track layouts and novel marble behaviours. The set supports hands-on learning through trial and error, helping develop spatial reasoning and fine motor skills while maintaining safe play standards for preschool and early-school children.

Advantages

This extension set complements the core GraviTrax Junior collection by introducing desert-style elements that broaden design options and stimulate imaginative scenarios. Components are sized and shaped for young hands, enabling straightforward assembly and modification without complex connectors. The pieces are compatible with existing GraviTrax Junior elements, allowing progressive complexity as a child’s building skills develop. The set is made to meet relevant safety expectations for the indicated age range.

• Classroom or playgroup activities that encourage problem-solving and creativity
• Extending an existing GraviTrax Junior layout with themed components and new track options

Key specifications

How to use

Attach the extension pieces to an existing GraviTrax Junior base layout or integrate them into newly built tracks.
