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 Discovery Kingdom sits in Vallejo, California, on San Francisco Bay's northern edge. The park combines a theme park with a marine-animal section, running coasters like Medusa (the West Coast's first floorless), Kong (an inverted coaster), Superman: Ultimate Flight, Joker 4-D Free Fly Coaster, and the newer DC Stunt Coaster. Dolphin, sea lion and bird shows run throughout the day.
Bay Area weekend visits, California school holidays, and the Fright Fest event drive Discovery Kingdom's peak crowds. Weekdays in April, September and October are dramatically quieter, with queue times on most rides staying short. Check live wait times for Medusa and Superman on arrival, and use our crowd calendar to pick a midweek date for shorter waits. The bayside setting makes for pleasant walking even on quieter days.
