Early Years and Original Launch

When Action Park first opened in 1978, it promised an anything-goes water and amusement experience that drew thrill-seekers from across the region. The park quickly became known for daring rides, minimal safety protocols, and a party atmosphere that attracted both fans and critics. However, this early momentum also planted the seeds for ongoing legal battles and operational instability that would shape its future.

Operational Instability and Frequent Closures

Throughout the 1970s and 1980s, Action Park remained open for much of the season, yet it cycled through periods of abrupt closure and revival. Investigations, lawsuits, and public outcry over numerous injuries forced repeated shutdowns of specific attractions and entire seasons. The question of how long Action Park was open often depended on which year and under what conditions you were asking.

1990s Redesign and Brief Revival

In the early 1990s, new ownership attempted to reposition Action Park as a more controlled destination, rebranding parts of the property and limiting hours. These efforts brought short-lived increases in attendance, but underlying financial and safety challenges persisted. During this window, the park showed up on many itineraries as open, even as rumors of its demise grew louder.

Final Closure and Legacy in Vernon

By 1996, sustained legal pressure, mounting insurance costs, and a tarnished reputation led to the definitive closure of Action Park as a standalone attraction. The site later evolved into Mountain Creek, with many of the infamous slides and reckless features removed or toned down. Fans still debate how long Action Park was open in its original form and what that era truly meant for adventure tourism.
