Ready to conquer a fear of heights? SheiKra, North America’s first dive coaster, will take you 200 feet up to the edge of a 90 degree drop—and that's just the beginning. Floorless cars give riders an unobstructed view of darkness matched with the 70 mph rush through an Immelmann loop, a second, vertical drop into an underground tunnel and a water feature finale, all packed into a half-mile of steel track.
