About Six Flags St Louis

Six Flags St. Louis sits in Eureka, Missouri, 30 minutes south-west of downtown St. Louis. The coaster line-up includes Mr. Freeze: Reverse Blast, Boss (a large wooden coaster), Superman: Tower of Power drop tower, American Thunder wooden coaster, and Batman: The Ride. A Hurricane Harbor water park is included with admission during summer.

Missouri school holidays, Fright Fest and Holiday in the Park events drive Six Flags St. Louis's peak crowds. Weekdays in May, September and October stay much calmer, with queue times on most rides dropping into single digits. Check live wait times for Boss and Mr. Freeze first thing on arrival, and use our crowd calendar to pick a quieter midweek date for marathon coaster sessions.

About Six Flags St Louis Ride Reliability

Which rides at Six Flags St Louis break down the most?

The Reliability table above ranks every ride at Six Flags St Louis by uptime percentage, total downtime minutes and number of separate closures in the selected month. Rides with higher downtime are usually older, more mechanically complex, or subject to weather-related closures.

What counts as a ride "closure" in these stats?

Any period where the ride's status flipped from operating to closed for more than a couple of minutes counts as a closure. Brief resets and scheduled early morning tests are excluded. A ride with 10+ closures in a month is almost certainly unreliable, not just temporarily out of service.

How do you calculate Six Flags St Louis ride uptime?

We track each ride's open/closed status every few minutes throughout the park's operating hours. Uptime percentage = minutes the ride was open divided by the park's total operating minutes. A ride that ran all day shows 100%, one closed half the day shows 50%.

Are some rides at Six Flags St Louis more reliable than others?

Almost always. Newer coasters typically have higher uptime in their first year, then stabilise. Classic flat rides and family rides tend to be the most reliable. Intense thrill coasters and water rides often sit toward the bottom of the uptime table because they're more complex and weather-sensitive.

How can I avoid riding something that keeps breaking down?

Check this page before your visit. If a ride you care about has under 80% uptime this month, prioritise it early in the day when reliability is best. Also check live queue times - if a ride shows "Closed" or hasn't moved in 45+ minutes, it's probably down for the afternoon.

Does rain or weather affect Six Flags St Louis reliability?

Yes - water rides close automatically in heavy rain, and exposed coasters may close in lightning, high winds or very cold temperatures. Our uptime figures reflect actual operations including weather closures, which is why uptime varies seasonally.
