Vortex, Steel roller coaster in Canada's Wonderland, Ontario, Canada

Vortex is a suspended steel roller coaster at Canada's Wonderland in Vaughan, Ontario, built by Arrow Dynamics. Its trains hang beneath a red track supported by dark blue-gray columns, climbing a 30-metre lift hill up Wonder Mountain before diving past the river, where the cars swing just above the water.

Vortex opened at Canada's Wonderland on 12 May 1991, built by Arrow Dynamics as a suspended coaster. Its track was laid out to follow the park's Wonder Mountain and the river below, making it a terrain coaster. In the 2005 season its trains ran with five cars instead of the usual six.

Vortex was built by Arrow Dynamics as a Suspended Coaster model, and its six-car trains seat four riders each in two rows of two, held by shoulder restraints. The cars swing out sideways through the curves and the drop, and the swinging continues even after the train stops in the brake run. In the 2005 season the trains ran with only five cars.

Riders must be at least 122 centimeters tall to board; height requirements are clearly posted at the entrance. Wait times can build on warm weekends, so visiting early in the day or during quieter periods works best.

Vortex's layout is nearly identical to The Bat at Kings Island, built in 1993, but Vortex runs six cars of four riders each, 24 per train, while The Bat carries 28. In the 2005 season Vortex's trains ran with only five cars. Its swinging cars keep rocking even after the train halts in the brake run.
