Someone has built the ultimate Hot Wheels track that's 12ft tall and packed with waterslides and elevators

Someone has built a Hot Wheels track that feels wildly out of proportion to the toy it carries.

This one doesn’t sit neatly on a floor or clip onto a coffee table.

It stretches upward, spills through water, and runs across an entire backyard.

And somehow, a single tiny car makes it all the way through.

Inside the backyard track packed with water slides and lifts

The build comes from Backyard Racing, and it was constructed in a residential backyard using the house itself as part of the layout. 

The track begins on the roof, immediately setting the scale before diving down into a maze of bright orange Hot Wheels pieces and homemade additions below.

From there, the structure spreads through the yard using ladders and a central tower that rises almost as high as the roofline. 

A standard Hot Wheels orange track forms the base of the build, but much of it is extended with homemade additions. 

A popsicle-stick bridge spans one gap, while drilled pipes, rain gutters, and hoses guide the car and water through other sections.

But the water isn’t just there for drama. 

Hundreds of gallons circulate through the track, pushed around by 12 sump pumps. 

Early in the run, the car shoots through a long tube waterslide and drops into a pool before being funneled into an orange bucket. 

From there, water drains through a small opening, feeding the car neatly back onto the track.

However, reaching ground level doesn’t mean the ride is over. 

A magnet-assisted pulley system hauls the car back upward, rollercoaster-style, restoring height without any manual reset. 

Later, a separate water-powered bucket lift raises the car nearly 12 feet straight up. 

The bucket holds it in place during the climb, then tips forward to release it back onto the track.

The final stretch mixes curves, water-fed speed, and elevation changes before ending with a jump into a bucket already filled with other Hot Wheels cars.

What makes this Hot Wheels track unusually complex compared to a normal build?

Most Hot Wheels tracks rely on a single gravity-powered drop. 

This one doesn’t. 

Water actively moves the car through multiple sections, while pools and buckets act as controlled transition points instead of dead ends.

The sump pumps keep the system alive, constantly recirculating water so nothing stalls. 

Lift mechanisms are built into the layout itself, not added as afterthoughts. 

Magnet-assisted pulleys return the car to height, while the water-powered bucket lift replaces the usual stop-and-restart approach entirely.

All of it works together as one coordinated system. 

A simple Hot Wheels car enters at the top and doesn’t need to be touched again until the very end.

It’s still a toy track. 

It just happens to behave like a miniature backyard ride.
