Roar, Wooden roller coaster at Six Flags Discovery Kingdom, US

Roar was a wooden roller coaster at Six Flags Discovery Kingdom featuring steep drops and sharp turns built from timber and steel support structures. The ride delivered rapid acceleration and sudden direction changes that created an intense experience for visitors.

The coaster was built in 1999 by Great Coasters International as an early project for the company in California. It operated for more than a decade before being transformed into a different attraction on the same site.

Roar was the first coaster fitted with Great Coasters International's Millennium Flyer trains, whose articulated design let the twelve-car trains negotiate the ride's tight curves. The name echoed the roar of the wooden structure and the trains. An estimated 11 million visitors rode it between its 1999 debut and its 2015 closure.

Roar operated in the Sky animal-themed area of Six Flags Discovery Kingdom from its opening on May 14, 1999 until its closure on August 16, 2015. Riders boarded two Millennium Flyer trains of twelve cars, two people per row, secured by seat belts and lap bars. The 1,003 m circuit included 22 crossings and a 61 m covered tunnel.

The coaster attracted millions of riders throughout its years before undergoing a complete redesign at the park. This transformation was notable because it marked the first time a wooden coaster from this manufacturer was so drastically reimagined.
