Choose by intent

Want rides? Go to the park. Want the haunt to be the point? Come to the Realm.

Six Flags Great America is one of the region's biggest entertainment destinations, and Fright Fest combines Halloween with the park's rides and entertainment. Realm of Terror is intentionally narrower: arrive, check in, enjoy the midway while you wait, go through the haunt, and stay for the rest of the event.
