Explore these parks with caution: incidents that shocked visitors over the years.

Theme parks promise thrills, fun, and unforgettable memories, but some have darker histories that are far from entertaining. From malfunctioning rides to unexpected tragedies, incidents at these attractions serve as reminders of the risks that come with adventure.
Here’s a look at 11 theme parks around the world that have experienced dangerous incidents, showcasing how even the happiest places can face troubling moments.
1. Action Park earned its infamous nickname, “Accident Park.”

Action Park in New Jersey became notorious for its poorly designed rides and lack of safety protocols. Visitors often encountered injuries ranging from minor scrapes to broken bones. Water slides, particularly the Cannonball Loop, were so dangerous they became legendary.
Multiple fatalities occurred in the park during the 1980s, including drownings and electrocutions. Despite attempts at improving safety, the park’s reputation as a hazardous hotspot grew, cementing its place in theme park history as both a thrilling and perilous destination.
2. Disneyland has seen accidents despite its “Happiest Place on Earth” reputation.

Other notable incidents include injuries caused by ride malfunctions and a death on the Rivers of America. Despite these events, Disneyland has worked diligently to improve safety measures, maintaining its iconic status while learning from its past mistakes.
3. Six Flags New Jersey faced tragedy on its Haunted Castle attraction.

In 1984, a fire broke out in Six Flags Great Adventure’s Haunted Castle, resulting in the tragic deaths of eight teenagers who were unable to escape. The attraction lacked adequate fire safety systems, which led to swift changes in theme park regulations nationwide.
