Corkscrew coaster made its debut in 1978, making Geauga Lake the first amusement park in Ohio and one of the first amusement parks anywhere to have two looping coasters. Swimming in the lake continued to be a feature at the park, and in 1983, the park added Boardwalk Shores, which featured a paddleboat marina, a new bath house, a children's swimming pool area and water slides. A year later, The Wave, the only authentic tsunami wave pool in the Midwest at the time, opened to rave reviews.
