See what you discover when you pass through the Adventure Tunnel! You can’t quite see through the darkness to work out what’s on the other side, but there’s only one way forward – straight through the middle!

Adventure awaits: The Adventure Tunnel has four "real world" sound effects that are automatically triggered when a train passes through it, creating fun and exciting play scenarios. You can also activate the sounds by pressing the button on top of the mountain. High upon the top of the mountain, a wobbly rope bridge awaits brave adventures to take the risk and walk across!

Realistic design: Shaped and colored like a real mountain railway tunnel, this sturdy plastic and wooden toy is finished with a realistic stone-effect surface and colorful flowers, making it easily recognizable for children versus the real world.

Part of the BRIO World: The Adventure Tunnel is fully compatible with other BRIO World toys via the wooden track that passes through its center, making it a great addition to any BRIO World railway layout.
