Behemoth is a steel roller coaster located at Canada's Wonderland in Vaughan, Ontario. Designed and developed by Swiss manufacturer Bolliger & Mabillard (B&M), Behemoth opened to the public in May 2008 as the tallest and fastest roller coaster in Canada, a claim it held until 2012 when Leviathan opened at the same park. Behemoth is similar to Diamondback (Kings Island), Intimidator (Carowinds), Goliath (La Ronde) and Nitro (Six Flags Great Adventure).
With its high speeds, tall heights and rapid changes in both direction and elevation, Behemoth is one of the most aggressive thrill rides in the park. It is also one of the park's most efficient, able to maintain a high hourly passenger capacity.The ride features a prototype seating arrangement to ensure an unobstructed view for every rider – a first for a roller coaster of this type. The ride lasts for approximately three minutes and subjects the rider to a maximum speed of 124 km/h (77 mph), achieved in less than 3.9 seconds. It features five air-time hills, a hammerhead turn and two helixes.
