Wonder Mountain's Guardian, Interactive steel roller coaster at Canada's Wonderland, Vaughan, Canada.

Wonder Mountain's Guardian is a steel roller coaster and interactive dark ride at Canada's Wonderland in Vaughan, Ontario. Its 305-metre track climbs an 18-metre lift hill, crosses Vortex's first drop, and enters the artificial mountain. Outside, grey tubular columns support the track, and a red rail runs above it; inside, track and supports are black.

Canada's Wonderland introduced this coaster in May 2014 after a decade of development and planning. The opening marked a shift in the park's entertainment direction toward interactive technology-driven experiences.

The ride tells the story of King Adelsten searching for his crown, stolen by the dragon Ormaar living within the mountain. Visitors follow this quest as they travel through different scenes that bring the legend to life.

Riders receive laser blasters to aim at digital targets throughout the ride and accumulate points as they travel. It helps to familiarize yourself with the controls before departure so you can fully enjoy the interactive gameplay experience.

The drop track falls 9.1 metres, one of the largest in the world, and the ride holds the record for the longest interactive 3D screen at 150 metres long and 4 metres high. The track runs about 305 metres in total, reaching 18.3 metres at the top of the lift hill.
