Adventureland
Adventureland in Altoona, just outside Des Moines, has been open since 1974 and is Iowa's largest amusement park. Monster is the steel coaster with the beyond-vertical drop, Outlaw and Tornado are the wooden coasters, and Phoenix, Storm Chaser and Draken Falls add more variety, with a large section of family rides. In the autumn it runs Halloween haunts on select dates.
Summer weekends and the weeks around the Fourth of July are the busiest. Weekdays early and late in the season are usually much quieter. Check the live queue times before you go and use the crowd calendar to find a good day.

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.
