Every year, it seems, this amusement park, at the eastern end of Île Ste-Hélène, adds some new and monstrous way to scare the living daylights (and maybe even your lunch) out of you. Vipère, a free-fly roller coaster, lifts you 107 feet up and subjects you to unexpected drops, vertical free falls, and 360-degree somersaults. Chaos is a single loop that takes you forward, backward, and upside down while sitting face-to-face with other riders. Titan, a giant swaying pendulum will have you—or the kids—soaring and spinning 148 feet above the park, traveling at speeds up to 70 mph. Demon, an extreme, high-speed ride, twists you, twirls you, and turns you upside down, then douses you with water jets. The park also aims to terrify with such stomach-turning champions as Endör, the Goliath, the Vampire, Monstre, and Vol Ultime. For the less daring, there are Ferris wheels, boat rides, and kiddie rides. The popular International Fireworks Competition is held here on Thursdays and Sundays in late June and July.
