Buy tickets and join the crowds at a game at UNI-Dome. If there's nothing on while you're there, you might like to check if there's a tour of the grounds.
This sporting facility is on the to-do lists of many travelers to Cedar Falls. But UNI-Dome isn't the area's only highlight. University of Northern Iowa, John Deere Tractor & Engine Museum, and Big Woods Lake Recreation Area are some other interesting attractions nearby.
