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.
Adventureland live queue times Six Flags Frontier City
Frontier City sits in Oklahoma City and is the smallest of the Six Flags parks, themed around an Old West town. The coaster line-up includes Steel Lasso, Silver Bullet (a Vekoma corkscrew), Diamond Back (a shuttle-style coaster), Wildcat wooden coaster, and Mystery River Log Flume. A White Water Bay water park operates at a separate nearby site during summer.
Oklahoma school holidays, US summer weekends and the Fright Fest event drive Frontier City's peak crowds. Weekdays outside school breaks stay very quiet, often with walk-on queue times. Check live wait times on arrival and use our crowd calendar to pick a midweek visit - Frontier City pairs well with a road-trip stop rather than a destination-park holiday.
