Omnimax Theater

The OMNIMAX Theater at the Saint Louis Science Center features a five-story domed screen that fills the entire field of vision — a genuinely different film experience than a standard movie theater or even a regular IMAX. When the camera pans across an ocean floor or launches into the night sky, you don't feel like you're watching; you feel like you're there.

The film selection focuses on natural history, science, and exploration documentaries — subjects like deep ocean ecosystems, ancient civilizations, space missions, and natural wonders. The format elevates these subjects dramatically: a film about the Grand Canyon on a five-story dome is a completely different experience than the same content on a television. For kids who are curious about how the world works, the OMNIMAX is one of the most effective learning experiences available in St.

Louis.

The theater is located inside the Science Center's main building, connected to the McDonnell Planetarium by a pedestrian bridge. Because general admission to the Science Center is free, your total cost is just the OMNIMAX ticket (~$10–$14/person), making it one of the better-value premium experiences in St. Louis.

A Science Center membership typically includes OMNIMAX benefits, which is worth considering if you plan to visit more than twice in a year.

For young children: the scale of the dome can be overwhelming for kids under 5, and films with motion-heavy sequences can feel physically intense. Preview the current film's content on the website before bringing very young or motion-sensitive children. For kids ages 5 and up, the experience is usually thrilling rather than distressing, and it creates strong memories.
