In the 1980s, Action Park in Vernon, New Jersey wasn’t just a waterpark - it was a rite of passage. Known nationwide as “Class Action Park,” this North Jersey amusement park pushed the limits with rides like the Alpine Slide, Cannonball Loop, and the freezing cold Tarzan Swing. Teenagers from across New Jersey packed into Vernon Township every summer for a day of chaos, thrills, and stories they still tell decades later. If you grew up in NJ, you already know.
